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

Bought this about a year ago. Used as a portable power source for portable digital audio recorders (Marantz 670, Tascam DR680 and Zoom F8) for location recording. Works great in that capacity. Decently light weight and portable.But -- I can't turn it off. The ON/OFF switch doesn't work. After a full charge, the LEDs stay on regardless of switch position. So, after about a week, I have to put it on the charger or just leave it on the charger all the time. It would be nice to just pack it in the bag with the recorder ready for the next gig, but I can't trust it to be ready, willing and able to run the machine at a moment's notice without slapping it on the charger for several hours to freshen it up.Inconvenient, but not insurmountable. I could get inside and re-wire the switch, but it should have been wired correctly during assembly.I'd probably buy another one if I could be assured it was wired correctly.
