Charging volts/mah etc?

[SIC08869]

So I have my usb charger, the original that comes with the kit and am thinking of plugging it into a blackberry wall charger that has the usb adapter plugin.

The specs on the wall charger are:
- "No Load Power consumption" 4-STAR rating
- Input: 100-240V 200mAh 50-60HZ 11-17 VA
- Output: 5V-750mAh


Is this too much/ too little power to charge:

King Logo autos
King Logo manuals
Diamond autos

Really don't want to burn anything up but I am finding that the standard wall charger that comes with the kit is going green and saying the battery is charged but the life of the battery is not the same as going through the usb charger. Last but not least, I know this sounds stupid but I just don't have enough available usb ports all the time.

the question is what are the volts and mah output on both chargers ?

 

[SIC08869]

so the v4l charger is 4.2 v 200 mah
electricity has never been my thing..

but the supplied usb connection is only 4.2 v and 200 ma

will the charger push too much load through the usb adapter?

Do you know the mah of the batteries you are trying to charge?

Rule of thumb, you don't want your charger to exceed the batteries
I have 3 sets of 14500 batts at 900mah I wouldn't use a charger rated for 1000mah

SIC0 sir that will power the usb charger without issue. All usb ports run at 5v, the ma rating otoh will vary. The standard for usb 2.0 is 500ma, for 3.0 900ma. They can be rated for higher depending on the mobo manufacturer. With a wall adapter you want to make sure it has the same or more ma than what the charger requires. The usb charger will still output 4.2v @ 200ma to the batt regardless of what it's plugged into. I won't suggest using the usb charger on the king diamond and stealth series though (especially the manuals), or leaving any battery connected for too long to it. They have the highest potential for overcharge which can shorten the life of a batt to outright killing it depending on how long it was left on.

Thanks Gents, looks like I am going to need to get one of the slim chargers. This also sounds like no charging overnight. Do the batteries continue to lose power rapidly when off the charger? I am guessing so if they are like normal batteries. Does anyone know if they do lose power what type of standby time do we get on a brand new fully charged battery?

No problem sir.
