DC 12V/2000mAh Lithium Polymer Rechargeable Battery Pack (Portable Charger External Li-ion Power Bank) with AC/DC Charger for LED Strip, Tape Light, CCTV Camera and most 12V Devices

I use it for LED lighting away from home. Lasts 2 hours on 80-100% brightness on a generic 13 foot roll of white leds. Between the two things it's $30 for a better mobile lighting solution than I have found anywhere.Just FYI in case you're new, use common sense with these battery packs, I opened up mine to see whats inside the case... yea they are cheap. LiPo batteries are not like AA batteries so read up a lil about proper care, so they don't overheat. some examples areDO NOT OVER CHARGE (the charger says when it's done not sure if it stops though),While charging, treat it like a lit candle: don't leave it unattended while charging or up against a wall or under a cabinet. (Couple friends I know had lipo batteries overheat during a charge and it burned up their garages a bit)Do what the included instructions say about first use and cycling it through a charge or whatever.Don't store it fully charged - that's a new one for me too. I guess you're supposed to let run down a bunch if you're not using it.

Not impressed. I purchased several of these power supplies. Half are working fine and the other half appear to take a charge but won't power on. I've already had the seller send a replacement only for that one to do the same thing and now I see they are Currently Not Available. I recommend finding a more reliable power source. Disappointed.

Consist output, Small compact, about the size of a deck of cards or so. It ran my diy LED 12V 3w light for hours without any issues. Definitely grabbing a second. Charging and discharging are from the same dc jack with power on. Will not charge if switch is in the off position. Also found out it is short/surge protected just cycle switch like a power strip.

Great little power pack. I have used it to power a desk air cooler and my DSL modem. It worked so well I'm thinking of getting another. I gave it a 4 because the instructions are unclear. It jumps between battery and AC power plug.

I love how small this thing is for the power I built a lantern with it for camping it works great. I was worried that it had no charge regulation chips in it, but I got it apart to check and it does so that's a plus in my book. I wish the seller was alot more clear with the specifications on here.

Great converter. Easy on/off switch and power recharge.

This is a wonderful mini 12v power supply. I Have used this for a month without any issues.

Works good for LED strip light. But the one I received did not have the "led indicator light" as decribed and pictured, it had the simple O/I markings.
