I saw this on Banggood and thought "wow, a charger that can do 2 packs, and it's like £20 !!" So I asked Banggood to send me one for a review and through the door it popped.
It wasn't quite the charger I expected - it's really basic, but seems to do one task ok - which may be of interest to mini quad flyers. Here's my video

So, if you want to charge up a bunch of 1300 4s's in a hurry, this may be something for you - if you are cheap, or don't want to spend big money on a proper charger. You could, of course, use parallel charging on a single proper charger - but I've had my own bad experiences with that.
So, not what I hoped, but y'know - it's ok for a specific purpose.
It looks like it has its place.
How well did it leave the packs balanced at the end of the charge ? Was it balancing well or were you finding inconsistencies ?
Well, nowhere in the instructions (what there was of them) did it actually say it balance charges, but at the end of the charges I did, all the cells were at 4.20v... but that said, I also charged them all from storage. I don't know if the same could be said if I tried some that were already out of balance. Next time I go out with a mini quad, I'll split some lipos between this and my normal charger to see if they are balanced at the end by fluke or design.
Cool will be interesting to see how it copes :)
