Ultrafire WF 188

Anyone else having issues with this POS? It's not my main charger but this thing is pretty much useless. I've tried to charge several different types of batteries on it and every time I have to jiggle the batteries around to make contact and even then if there is the slightest vibration, it stops charging. I bought this because it had the option of choosing the mAh but it's so poorly designed that I'd rather just chuck the thing in the trash...
No point really to this post, just venting. I'll stick with my Ultrafire TR 001

I have one on the way for a backup charger, I hope thats not the case They have gotten pretty good reviews on various forums perhaps there is something wrong with yours?

I have one and have had no issues with it. BTW it is the only charger that I know of that can charge a 26650.

It very well could be that I have a bad one, but I just can't get it to charge. It's hard to explain but I have to put the batteries at an angle to even get the LEDs to change from green to red. I'm not even sure if it's even charging the batteries

That's odd.

I have one but have no problems with it. The build quality is not that great but its OK for China and it does do the Job.

The only thing that I have observed is that the moving terminal on the rail sometimes sticks . Spraying it with some contact cleaner could help.

The positive contacts can be a bit of a pain because the nipple of the battery can slide off. One solution is to use magnets. I have no problems holding the nipple in place with a couple rare earth magnets.

That's a very good idea trogg, I'll give that a try. Thanks!
