Lavolta 12V DC 3500mAh Rechargeable Battery Pack for LED Light Strip - 45Wh Lithium Polymer Power Bank Portable Supply with Y-form Splitter Cable - Works for Home LED RGB String Lights & CCTV Camera

This thing is a peice of junk..... It only held one charge! I used this till it was too low on power to run a 2ft rgb led strip.... I charged it and it never worked again..... Save the 20$ and buy something else!

I bought this because of the dimension in the description, when it arrived, it was not to the dimensions listed. It was bigger and didn't fit in the space I needed it to go.

Doesn’t hold its charge. I’ve only attempted to use this a handful of times for a 5ft long LED light strip. I have left it on for less than 10 min, turn it off and the next day there’s no juice.... junk box

Battery lasted for almost 25 cycles and now doesn't hold a charge for more than 2 min. DO NOT BUY THIS ONE.

A good idea, adequately implemented.
