Oh even better! Darn good price!
I’m thinking at ordering this or Miller 102 V5 mainly for backup power for my phone and 3DS. Which one has better circuitry?
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...
Like this one (the latest V5 Miller charger)

- Single TP4056 IC for battery charging
- Single PT1301 IC for charging devices
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!
looks good.
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.
Thanks for the nice review on this!

Order two of them to try out. Thanks for the review on these.
They do come with lid open so it’s not an issue…
So V5 is using 2 separate ICs while this one using the same IC for both tasks?
Can anyone recommend some good batteries to put in these? Ideally something under $6? Thanks!
Yes, per the data sheet, it eliminates two separate channels worth of electronics and soldering
I am planning on using laptop pull panasonics (or sony [the red ones])
Decent enough and can handle 1A charge and has enough mAh to actually be worth it
Panasonic laptop pulls? Link?
That is great 411. The coast looks clear to order more then…
thanks!

Excellent review, what can we buy if we only have protected cells, like the 3400 Panasonic?
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. 
They are Sanyo laptop pulls…sorry
It’s cheap. But I didn’t see it with a brand li-on battery. Don’t know how long it would last compared to these:

Ordered 5, no pink tho 
It comes with no battery at all. But I guess if you put 3000 mAh cell of quality brand you will get similar runtime to the RAV power (If the later indeed has 3000 mAh battery inside)
