Voltaic Systems Emergency USB Led Light - Waterproof, Dimmable Brightness Levels & Touch Control, for Camping, Patio, Tool Shed or Cabin, Emergency Kit

Very useful for lighting a space. I use mine with a power bank. I like the stepless brightness control, and the memory turn on feature. It comes on with the same light level from when it went off. I bought two!

What is a little emergency light. The one off switch is a little weird but the light is great. Thank you very quick shipping.

This thing is awesome. Its small enough to carry in a pocket and still puts out an amazing amount of light. It was in the rain and worked perfect. Seems very well built and durable. You can use it as a reading light, a work light, or a light in the tent. Lots of uses. Doesn't draw a lot of power which is a huge plus. Great value for the money.

When I bought this I was expecting a light that was about the size of a mason jar lid from the pics. When I received it I would guess it’s maybe the size of a silver dollar at most. I was going to return it but after I figured out how to turn it on I was amazed at how bright this little thing was. Although I won’t be able to use it for what I was hoping I’m still keeping it as an emergency light and camping. It will be perfect hanging in a tent. You can use a portable phone charger to power it. To save someone else the frustration I went through you hold your finger on the glass to turn it on and cycle through brightness and to turn it off. If using a portable charger I recommend keeping it on low as much as possible because it drains your power much faster on high but omg it is bright. I was looking at it when I finally figured out how to turn it on and I seen spots for hours. If this review helped you in any way please upvote it really helps. Thx

It's a cool little light

I used this with one of my solar generators. It draws 1-2 watts on high and on the lowest setting, it doesn’t even register a draw. On high, a 250wh power station (think ecoflow river) will power this for days and days. With only intermittent use at night for a couple hours camping or during an outage, the draw is so negligible it hardly impacts the power source. It can be run from usb power packs or a wall wart. For its size and very minimal draw, I’m thoroughly impressed with the brightness and long run time. It gets a little toasty on high but it dissipates heat well.

Just a handy, great responsive light. Barely touch the light to turn on/off. Hold to brighten, hold to dim, touch again to turn it off. I have mine wrapped around my bed/phone holder. The arm comes out far enough that when I’m lying bed, if I need a light, that is my first go-to. I would buy again but I like a “bright white” bulb, and this is a yellower light. Great sturdy light. So handy to travel with, read a map, keep in your car, up on your visor ready for a tap. Keep in your purse, mom’s, just in case.

I already had a couple of Voltaic Power Banks, so this was a no brainer. The light is a bit smaller than it appears in the photos but sure is bright. I needed a battery powered light for my van for very early morning surf trips. I get to the beach at dark and need a light to help getting on my wetsuit and getting other stuff ready. I did not like running my van to power the dome lights or just using the van battery and running the battery down. This is perfect for my use. I like the long cord and that it detaches from the light, makes it easy to run the power cord through nooks and crannies for a sanitary install. Plenty of light for reading or rolling joints. East to turn off and on as well as adjust brightness. Great light, small but bright, not cheap but very well designed and well made.
