Well it arrived today! However, I did NOT receive what was pictured on Tmart's website! (Does this surprise you?) Here is what I received:
It's not a "YiboYuan" branded charger, and it's only rated 350mA! Doesn't look so great inside, but I'm no electronics guru so I need some of you to chime in and tell me if these internals look acceptable or not. In that last photo, the AC prongs are in the top center with black wires attached, and the output wires are going off the photo on the right side. I have not powered it up or anything. So does this look usable? Or does it look unsafe or untrustworthy?
This is the same one I have and it works well, just charges slow. Terminates at 4.35 like a champ.
I bring up the cells to 4.20 on another charger, then top off with this one.
Runs cool, no problems.
HTH
I have yiboyuan universal version, and it is very good.
I can charge any cell phone battery, it is adjustable.
I got it from DX, which is the same one on this link
Well today I received my two new YiboYuan chargers I ordered on Ebay (see post#26 above). Came from a US Warehouse, not extremely fast, but not terribly slow either (faster than Tmart!). I did in fact receive YiboYuan chargers, HOWEVER I received two model AC-11's and not AC-10 (it was only the photos in the Ebay listing that showed AC-10, it wasn't stated anywhere in the listing). I don't think this is a big deal though since I can't spot any difference between an AC-10 and an AC-11. Both are 4.35v @ 600mA charge rate with a USB output as well.
In any case, here are some pics:
The internals don't look as sophisticated as the first charger. My first question is, where is the AC -> DC circuitry (i.e. the 4 way bridge rectifier circuit)? So how does this one look? Does it look safe?
Thanks HKJ. Well I won't ever use it on 230V AC. So you think it's safe for 120V AC use? And what is controlling the charge termination? I don't see an IC like I would expect.
So it seems the first chargers I received from T-Mart would be better suited to use than this second set. I would definitely charge up to 4.2v on another charger first due to the slow 350mA charge rate on that first charger. Ugh - thought I had a good solution going.
