This one...the miller just like any of the other single cell portable power banks have 2 separate circuits, one for charge of the Li Ion battery in the pack, then one for the boost output for 5vdc, this one both are contained in one chip, 1A both directions (probably less due to inefficiencies and heat loss)
Unless they have new miller chargers that have something similar...
I was tempted to order one of each of 6 colors from BIC. At $2 each, even just the cell holder portion is worth it.
However, I resisted the urge and only ordered 1 each of black, white and pink.
See, I CAN control my addictions
I had 10 in the basket and hovering over the buy button then remembered my wife put the kabosh on my spending till payday, already bought 4 at $1.00 more expensive at banggood
I have a BUNCH of panasonic laptop pulls (thanks 18sixfifty) and itching to try em out, I have two super cheapo tube ones that just can’t hack it and end up going dead because they leave a draw on the battery all the time (plus the batteries suck anyway!)
Just imagine a "mod" and putting this on a 4x parallel 18650 battery pack!
Initially I had over a dozen in my cart with the intention of gifting these all out but then I thought -> “I’d better order just one to start out.”
Being one handed I’m not sure how much trouble I might have getting this thing open. Better to just try one out now. I can always order a bunch later if it’s a go.
Thanx for the review. I have bought 10 of these and am very satisfied with the performance of each. I use unprotected Sanyo 2600mAh cells and they’re good for at least one charge cycle for my family’s gadgets.
