I Tested And Reviewed 10 Best Battery Backup For Power Outage (2023)

After reading multiple reviews about this bulb, it seems that there are mixed experiences with its functionality. Some users have reported that the bulb stays on even when the lamp is turned off, while others have had no issues. Upon further analysis, it appears that this discrepancy may be due to following the instructions provided or possibly receiving defective bulbs.

The instructions recommend leaving the bulb on for 10 hours upon initial use. Although this may seem excessive for a small battery, it is likely that the bulb is using this time to calibrate and determine the characteristics of the wiring it is connected to, such as resistance or capacitance. Once this calibration is complete, the bulb can differentiate between a lamp cord or light switch and a power failure.

In my own experience, after charging the bulb for 10 hours, it behaved as expected. When I turned off the lamp, the bulb went out. When I turned it back on and unplugged the lamp, the bulb also went out. However, when I turned it back on and flipped the circuit breaker, it remained on, simulating a power failure. Therefore, based on my personal experience, I believe that this bulb will function correctly for most users.

One minor issue that may affect some individuals is that the illuminated portion of the bulb is positioned closer to the top than usual. This can result in a concentrated light dispersion across half of the lamp rather than an even distribution. I have attached photos illustrating this issue. If the bulb is oriented vertically, this should not be a problem. It is important to note this aspect for those who may be concerned about the aesthetic appearance of the light.

I recently purchased these bulbs for my bathroom light, and I must say, they have proven to be incredibly useful. Last year, we experienced several power outages, and relying on a flashlight to light up the bathroom was quite challenging, as it provided more of a spotlight effect. However, with these bulbs, I can now easily illuminate the entire bathroom during a blackout.

One aspect that stood out to me is the color temperature of these bulbs. They emit a 6500k light, which is much whiter than the regular daylight that typically runs at 5000k. This bright white color is perfect for bathrooms and the garage. For bedrooms and living rooms, however, I prefer a warmer color.

What I found particularly cool about these bulbs is that they come with a tiny socket switch. This feature allows me to have some fun with my kids by tricking them with the lights. I simply rub my socks on the carpet and use the switch to surprise them. It adds a playful element to these bulbs.

Having purchased these bulbs multiple times, I have learned a few things about using solar lights. Firstly, it is crucial to keep them charged to ensure optimal performance. While they can function as standard LED bulbs, they truly shine during power outages. When the power goes out, simply turn the switch to the on position, and they will provide reliable light. If the LED glows dimly when the switch is turned off, it may indicate that the bulb electronics are deteriorating. Typically, these bulbs last around three years before this happens. I recommend keeping fresh bulbs on hand to replace any that go bad. If you receive a faulty bulb in your order, reach out to the company directly for a replacement or credit, rather than contacting Amazon.

These bulbs have proven to be effective in providing light during power outages. After charging them, I tested one and it provided approximately 4.5 hours of light. As for their longevity, only time will tell. However, I did encounter an issue with using these bulbs alongside smart devices in my home. When the power goes out, they do not remain lit if the lamp is connected to a smart plug. To overcome this, I had to unplug the lamp from the smart plug and directly connect it to the wall. Once I did this, the bulb illuminated. Therefore, if you rely on smart plugs for your lamps and experience a power outage, you may need to make this adjustment.

These bulbs are a great addition to any study area or space without overhead lighting. They have a quick charging time of only 2 hours in a lamp and can easily be hung above a desk. The bulbs stay at maximum brightness for 3-4 hours and then gradually fade, but they continue to provide light for more than a day. What's even better is that they can be charged and stored, holding the 3-4 hours of brightness for days until needed. Made from sturdy plastic, they are portable and can be thrown into a backpack without worry.

A previous purchase of similar bulbs proved to be useful, but this set of 4 bulbs is even better. They are much brighter, resembling daylight rather than dusk. The difference is amazing and has left the reviewer very happy with the product. They highly recommend these bulbs to everyone, as it's better to have them and not need them than to be in the dark regretting not getting them earlier.

Another customer purchased these bulbs to send to their family in Cuba to use during power outages. They are extremely bright, have long-lasting battery life, and are practical and easy to use. The reviewer highly recommends them, giving them a 100% rating.

Living in a rural area with frequent power outages, one customer came across these bulbs while looking for something else. They purchased a set for their neighbor and found them to work fantastically. The bulbs can be easily installed in fixtures and lamps, and during power outages, they last for 5-6 hours. This is a much better alternative to using propane lanterns and candles. The bulbs also come with adapters and hanging hooks, making them portable as well.

For another customer, these bulbs proved to be a great investment. They purchased a set earlier in the year and were able to effectively use them during a hurricane. The bulbs lasted all night long, providing much-needed light. This second set was purchased to share with a friend, highlighting the high recommendation for this product.

I recently discovered the existence of products like this, and I must say, I am impressed. I needed a power source for my outdoor performances as a street musician in Atlanta. This unit exceeded my expectations by far. I was able to power my 200 watt EV speaker, guitar pedal board, and mixer for a 2-hour gig, and the battery only used up 20% of its capacity. This means I could have done 5 shows before needing to recharge.

I accidentally dropped the battery on concrete, and to my surprise, there was barely a scratch, and it continued to work flawlessly. The durability of this product is impressive. I also appreciate the option to charge the unit with both the AC adapter and the USB C port simultaneously, as it speeds up the charging time by about 30 minutes.

The versatility of this unit is another highlight. It can be used with any device that has a USB or regular plug, and it can even charge other batteries and phones. With three light modes, it is also useful for camping and blackouts. Considering its functionality, the price is very reasonable.

I purchased this unit for a fishing trip to Canada where there was no AC electric available. I also bought a solar panel to recharge it. It was able to power my CPAP machine all night with 25% battery power remaining in the morning. This product truly was a lifesaver and worth every penny.

The 80Ah unit offers great value for its price. The 10 watt wireless charging, faster charging with type C and the 70 watt AC charger are all impressive features. I also appreciate the ruggedness of the unit, allowing me to charge it in my vehicle through DC. It is lightweight and compact with two outlets, making it convenient to use. The fan operates quietly, and the unit charges in just 5.4 hours with the AC adapter alone.

One downside is that it does not come with a case for accessories, and it lacks a wattage display, only showing the percentage of charge. Additionally, it does not have a built-in DC port, but an external DC plug is provided for 12V devices. It cannot charge 12V batteries, but it can power 12V devices. It is important to note that the unit should not be left turned on when not in use.

Update: I may have been mistaken about its ability to charge a dead 12V battery. I will test it and provide an update on its performance in this regard.

The Duracell portable power station is a surprisingly lightweight and compact device that is perfect for RVs or cars. It holds a charge well and is powerful enough to accommodate multiple devices.

This power station is incredibly versatile and well-made. I have used it to run power tools remotely and even powered appliances during power outages. I was even able to use it for a unique wedding proposal in the woods, where it powered several thousand Christmas lights. The design of the power station is user-friendly and the charging time is impressively short considering the amount of runtime it provides. Additionally, the included solar panel is a fantastic feature for camping and other outdoor activities. It folds up easily for convenient storage.

One of the main reasons I purchased this power station was for emergency situations, as power outages are a constant threat in California. I can confidently say that this battery is awesome. It is easy to use and can power or charge most of the devices we need during an emergency. It provides a sense of safety and security for my family. The solar panels are a great addition, as they ensure we have power even if we lose electricity for a couple of days. But the added benefit is that our family loves going camping and spending time outdoors. This power station and solar panels have made our outdoor movie nights much more enjoyable, as we can take the speaker and projector anywhere with us.

During a recent power outage caused by a storm, I plugged my refrigerator into this power station and it kept it running all night until the power came back on.

The power station arrived well-packed and was already 65% charged out of the box. It only took 3 1/2 hours to reach 100% charge when plugged into a wall outlet. I tested it with a large shop vac, and it powered it without any issues for 2 hours. I then plugged in a battery tender for an ATV, and it showed 40 hours of power reserve while in charge mode. I expect it to last even longer in trickle mode. Lastly, I plugged in a shop radio, and it showed 103 hours of power reserve.

While this power station may not be able to power larger devices like compressors or circular saws, it is incredibly convenient for powering up smaller toys and tools in the shed or driveway without the need for multiple extension cords.

The listing for these bulbs may have been poorly written, but don't let that deter you. These bulbs are a great choice, especially if you live in an area prone to power outages like the coastal mountains of California.

What sets these bulbs apart is their versatility. They function as regular LED light bulbs that can be used in any standard North American light socket. However, they also have an internal battery and a built-in processor, allowing them to operate even when there is no electricity. The internal battery can be charged by simply placing the bulb in a lamp and turning it on.

Controlling these bulbs is easy. They come with two mounting bases that have a push button switch. You can simply push the button to turn the bulbs on and off. In case you misplace the bases, you can still operate the bulbs by completing the circuit on the base of the bulb using a piece of wire, your hand (if held correctly), or even a wet cloth (which surprisingly works). The bulbs also come with two rectangular sockets that can be used to connect the bulbs to electrical plugs, allowing you to use them as emergency lights when the power goes out.

In terms of brightness, these bulbs have two settings. The first time you turn them on, they are on the "bright" setting. If you turn them off and then on again, they switch to a dimmer setting.

While these bulbs are impressive, there are a couple of unknowns. The type of batteries used in them is not specified, so it's unclear how long they will hold their charge. Additionally, the longevity of the bulbs in terms of producing light is also uncertain. Time will tell.

One reassuring aspect is that these bulbs are UL listed, meaning they have been tested by a North American laboratory and deemed safe. This is an important factor to consider when purchasing products like this.

On the downside, the hanger on the included base is made of thin plastic, which may not be very durable. Additionally, using these bulbs as flashlights may not be ideal as they are bright but not directional like traditional flashlights.

In a real-world scenario, these bulbs have proven to be a great solution during power outages. They can be easily set up in a lamp base with an on-off switch on the cord, placed on top of a refrigerator for better illumination. The light bounces off the ceiling, providing sufficient lighting for the kitchen. The bulbs last for hours, and when the generator is running, they can be charged. Switching to battery power is simple, just unplug the lights from the generator feed and use the included rectangular plug to close the circuit. The switch on the lamp base cord can then be used to turn the bulb on and off.

Given their performance, it's highly recommended to consider purchasing more of these bulbs to ensure you have sufficient lighting during power outages.

The emergency lightbulbs that I purchased have been an absolute lifesaver. Living in an area prone to power outages, I have experienced numerous instances where I was left in the dark. However, since I installed these lightbulbs, I no longer have to worry about being without light during emergencies.

One of the standout features of these bulbs is their ability to function without electricity. They work just like regular lightbulbs, fitting into the same socket, but they have the added benefit of charging up while the power is on. This means that when the power goes out, these bulbs remain lit up, providing much-needed illumination.

I particularly appreciate the convenience and peace of mind that these bulbs offer. They have come in handy during natural disasters such as earthquakes and storms, as well as unexpected power outages. I no longer have to fumble around in the dark or rely on candles for light. It's a simple yet effective solution that has made a significant difference in my household.

It's important to note that these bulbs are not suitable for all fixtures. They rely on the completion of a circuit, so they may not work in every type of lighting setup. For example, free-standing lamps can trick them into staying on all the time. However, they work perfectly in recessed cans and other appropriate fixtures.

Additionally, it is worth mentioning that not all bulbs have the same lumens, so mixing these bulbs with others from different manufacturers may not be possible. However, this can easily be overcome by replacing all the bulbs in a room with these emergency lightbulbs or using them in areas where they won't be mixed with other bulbs.

I recently purchased these LED bulbs and I have to say, they have exceeded my expectations. While there was initially a bit of a learning curve in understanding how to properly use them, once I got the hang of it, they proved to be amazing.

One important thing to note is that these bulbs need to be kept in a closed circuit in order to function properly. If you simply unplug the lamp without connecting the prongs of the plug with a wet cloth, the bulb won't work. However, if you keep the plug inside the wall outlet, the bulb stays in a closed circuit and will work as expected when you turn on the switch. A simple way to test this is by connecting the tip and the threads of the base of the bulb with your fingers – the bulb will light up.

I actually bought these bulbs right before a planned power outage and I must say, we were excited about it for the first time ever. We weren't sure if the bulbs were fully charged, so we kept them on for about 10 hours in the lamp to ensure they were charged. When the power outage finally came, we were thrilled to see that the bulbs worked as soon as we flipped the switch.

In terms of performance, these bulbs are just like regular-sized LED bulbs. They provide good brightness and work great for energy-saving purposes on a daily basis. When the power is out, they can operate on battery for approximately 4 hours. Additionally, there are some other cool ways to use them, such as lighting them up with your fingers to show a magic trick, or using them as a lantern by attaching a cook cap.

I must also mention that during Hurricane Zeta, these bulbs proved to be a lifesaver. When the power went out, the bulbs immediately turned on since they had been on for 8 hours prior. They provided ample illumination and allowed me to grab my other long-term emergency lighting and power stations. In the darkness of a hurricane at night, these lights were incredibly bright and reliable.

Since then, I have been using these bulbs regularly and they continue to impress me. They are bright, do not get warm, and are as energy-efficient as the regular LED bulbs they replaced. I have been so pleased with the results that I even purchased two more for my bathroom ceiling light and as a spare.

The pack of 2 rechargeable light bulbs has proven to be an essential addition to any household. These bulbs are not only useful during power outages but also for various other situations. The convenience and versatility they offer make them a smart purchase.

One of the most significant advantages of these rechargeable light bulbs is their usefulness during power outages. It's always reassuring to have a backup light source in case of emergencies, and these bulbs provide just that. With a battery backup using a built-in 2200mAh battery, they can last for about 6-7 hours at the highest brightness level. This makes them perfect for use during night-time power outages.

These bulbs are also ideal for camping trips. The hook attachment allows for easy hanging in tents or other shelters, providing much-needed illumination in dark environments. Additionally, the bulbs offer three levels of brightness, giving users the flexibility to adjust the lighting according to their specific needs.

Another situation where these light bulbs prove to be helpful is when a work light is required. With their high brightness and convenient hook attachment, they can be easily hung up wherever needed, providing ample illumination for various tasks.

Furthermore, the fact that these bulbs are rechargeable eliminates the need for constantly replacing batteries. This not only saves money but also contributes to a more sustainable and environmentally friendly lifestyle.

I recently had the misfortune of experiencing a power outage in my town due to a hurricane. With no electricity for nine days, I was desperate to find a reliable source of light. A friend recommended these emergency light bulbs, and I must say, they exceeded my expectations.

What sets these bulbs apart is their ability to function just like regular bulbs when the power is on. However, when the power goes out, they continue to provide illumination, ensuring that you're never left in complete darkness. This feature alone has been a game-changer for me.

I've been using these bulbs for about a month now, and I'm genuinely impressed. In terms of longevity, I've decided to test a couple of them as regular light bulbs to see how long they last. I will update my review accordingly. So far, the only noticeable difference is that the bulb continues to work even when removed from the socket. This versatility is a major plus.

Not only do these emergency bulbs perform exceptionally well, but they are also incredibly easy to use. Upon receiving them, I attached the provided hanger attachment, and they immediately lit up, emitting the same brightness as a 60-watt bulb. However, it's important to note that these bulbs are not compatible with fixtures that accommodate multiple bulbs. In such cases, you'll need to keep the bulbs charged and hang one up in a safe place, ready for when the power goes out.

Some people may find this setup a bit inconvenient, but I believe it's a small price to pay for the benefits these bulbs offer. Compared to battery-operated lanterns that require ongoing battery replacements or the potential fire hazard of lighting candles all over your house, these emergency bulbs are a much safer and affordable solution.

One of the standout features of these bulbs is their impressive battery life. They can stay charged for up to 50 days and only require a few hours to recharge. This makes them perfect for both regular use and emergencies when the power goes out.
