Review on TalentCell Rechargeable 6000MAh 12V DC Portable Li-Ion Battery Pack With AC/DC Charger For LED Strip, CCTV Camera - Black by Daniel Icyblue

I bought two of these, one for my bike and one for a glow-fur vest. The vest has over 5 meters of RGB SMD5050 LEDs in it, 60 LEDs/M, and one of these packs ran it for several hours in color changing mode. Be aware that it has a max output of about 3 amps, and if you overdraw that it will shut off. If I run all my LEDs on white for more than a few seconds, the amperage protection will kick in and cut power. Two of them in parallel (and they conveniently come with an adapter to do that) has no problems whatsoever.On my bike, one of these packs runs 5M of 120/M blue SMD3528 LEDs, for several hours at full brightness with no trouble whatsoever.One of my two packs has a slightly dodgy switch, which won't kick on about one time in 5, and I'm worried it will fail altogether soon. Other than that, I'd give this unit 5 stars.
