Bests & Worsts Reviews from Amazon

Tired of trying to figure out which backup battery to get? Well, I'm here to save you some trouble and disappointment. I've bought a number of batteries, and ended up being an inadvertent battery tester. FORGET any battery that claims to be more than 30,000mAh- it would have to be the size of a cement block to be the 500,000 that some sellers claim. The ROMOSS 30 is the best BY FAR of 7 that I tested, including an AUKEY. How well does it work? It runs the iPad Pro 12.9" for over 12 hours of drawing in Procreate (which eats batteries) without using any internal iPad battery power. OH YEAH. I do love stuff that works! (The 30 is a thick, hefty battery, and if you're familiar with Lipo batteries, it's what you'd expect for that amount of mAh's (that's mili-amp hours)
