Voltaic Systems USB Touchlight - Waterproof LED Light with 3 Brightness Levels

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!

Haven't used yet but when I go camping I will I plugged them in to make sure they worked for such a small light it is very bright and dimmable by tapping the light itself very kool

The brightness is continuously variable from full brightness down to a level more dim than you would probably ever need. I like that this light source is compact, and can be deployed in a variety of situations. Operation from USB greatly helps the versatility. My only misgiving is that the color temperature is fairly cold. This makes it useful for a task or utility light, but not as soothing to the eyes when reading, or generally relaxing in the evening. My suggestion for future products would be a version of this with a much warmer light. This is the only reason I am giving it a 4 star review. Otherwise, it seems to be a quality product.

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.
