Another interesting charger that may be useful. Interested in how it would perform charging LiFePO4 and Lithium Ion cells.

Quite cheap one cell simple-charger, even cheaper than the Lii-100
It will most likely be junk like most *fire chargers. It’s not worth the time, really.
I have ordered one. It will go in the low priority queue, i.e. it can be a long time before I publish a review.
There is a big risk it is a bad charger, UltraFire often is.

I found this while searching for a small but >1A charging circuit
This thing is interesting, because you can choose 4.2 or 8.2V - I think the charging current drops to 1A at 8.4V
also, the input-voltage can be pretty high.
If you are bored (lol)… 
I have ordered one, but it will probably be a very long time before I get time to look at it.
Hi HKJ, there’s the new 4-slot charger Liitokala Lii-402:
http://www.liitokala.com.cn/productView.asp?id=47
It would be cool if you can lay your hands on one of these when they are available 
I expect to test it, but I do not have any in queue and will very soon have a lot of other chargers in queue (DHL was supposed to deliver them today, but it looks like they where a bit too optimistic).
Sofirn, again - very cheap 8-slot charger.
But does it trickle charge and hurt LSD cells? Can’t tell.
Got a guess on this one?
I recall some chargers were wired so badly that they could put line voltage on the outside metal frame of cell phones.
Bad thing to take into a bathtub.
And there they are: cell phone charger hot voltage outside hand risk problem electrocution - Google Search
That is a major risk with any charger that get two skulls in my list: Index of tested and reviewed USB power supplies/chargers
Shouldn’t they installed RCD/RCCB on the breaker especially for bathroom in the US?
Probably only when they change an installation or make a new installation.
have you test this charger seems like an okay price for a 2A charging. Really lacking information, if its charging 2A at all slots that would be good.
AWT C4 charger
No, but it looks interesting. With the amount of chargers I have in queue just now, I will not order new chargers for test.
At a later day I expect to check this thread for interesting chargers.
I remember for that later day also a Nitecore SC4 . 
I have made a memo in the second post of the thread.
10 amps....... O_O
