Review on Rechargeable 12V 11000MAh 9V 14500MAh 5V 26400MAh DC Output Lithium-Ion Battery Pack For LED Strip, CCTV Camera, Portable Li-Ion Power Bank With AC/DC Charger - Black by Jacob Richmond

This thing is great. I actually bought it for an audiophile function , to power my Analog-to-digital and digital-to-analog converter. it separates my converter from the mains helps remove noise etc. It supplies super clean 12v power to my LYNX HILO Reference AD/DA Converter for extended 8+ hour listening sessions.a whole day's listening .without any issue whatsoever; I plug it in and charge it at night. worked so well I bought a second one. We use that one as a portable power source. We recently used it on a long trip to keep our phones and tablets charged .it worked flawlessly. I was able to recharge my phone, my wife's phone , and our 2 tablets .3 times a piece each, and it still had charge left in it. It is pretty nice to know that no matter where you go, with this thing fully charged, you'll always have power. It also holds charge reliably for a very long time as well. Fully charged it sat for 12 days, until I used it.didnt miss a step.
