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

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.

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!

This is such a handy useful USB LED light! As others have already said. I use it in conjunction with my NESTOUT Elecom power bank, simultaneously with my NESTOUT lamp. During a recent power outage I used this light and was able to have light where ever I wanted it, close-by, or separated from my other lamp light source. Use it as a remote powered trouble light in tight places, use case is pretty amazing. It's just COOL!

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

This is amazing, sturdy and versatile. The long cord gives flexibility to use indoors and outdoors. The light is very powerful, and does get hot with extended use. I use it to illuminate areas that don’t require extended use. I’ve purchased another one to use in the field hooked up to a battery pack.
