Can i connect 2 of these to one battery at once with no ill effects? I want one to be used as a tender, and the other to connect to a USB adapter on

You can connect two of these to your battery but I don't recommend charging the battery and using the USB at the same time.

I don't see where it would hurt to connect a dozen, so long as only one is connected to the charger.

You can connect 2 of these. However, this will increase resistance at the terminal. We also carry a USB adapter that can connect to this which you can unplug when you need to charge the battery. http://www.impactbattery.com/catalogsearch/result/?q=mbusb&x;=0&y;=0

Yes, you can connect two of them, it should not matter but I would not run both at the same time.

I see no problem with both being connected at the same time. Small charge is delivered as needed to keep battery charged. USB adapter would never notice.

I tried charging two at once and it didn't work. I think what was really intended is the one mini/micro whatever it is connection on the face is the only charging connection... On the positives, its a neat little device and I do mean little, the power adapter is much bigger than the hub.. I would still recommend buying it just based off its overall size and portability, I just kind of like the thing... Sorry no I dont think its capable of charging two devices at once.

No, not recommended. If the required load to maintain the two batteries (assuming they are wired in parallel) is unbalanced, this can damage the charger. These are cheap chargers, save yourself some grief and buy two.

You cannot charge and use it simultaneously. If it's on when it's charging, the battery will become damaged.

When you connect them like this, they operating in parallel - same as if you had wired the batteries in parallel yourself. Each battery will receive the same charging voltage. For some batteries, this this will be the correct charging voltage, However, the other batteries could be over-charged or under-charged.

No. The charger would be damaged if your device needed 2 amps and the charger only provided 1 amp. The 2 amp rating means it could charge 2, 1 amp devices at the same time. I've used it many times without issue on a variety of devices.

I don't think you should try using adapters and more battery than this supposed to take 1.5 volts each adding to many 1.5 volts can break it and they will not last as long d is a lot of power just use the d I say

Depends if you connect the controller to the panel then you could connect it to each battery but not both at the same time.

Yes you can sharge 2 lipos at the same time, or 1 lipo and 1 NiMh, as I ofter do. Brands of batteries don"t matter, just type, and size. Charger works great!

there is no way to charge 2 NiMH batteries at once? adapter board such as the one for lipo? is there a dual charger designed to charge 2 NiMH batteries at once?

Sorry for the lateness of the reply.,But in answer to your question... Yes you can use two batteries at the same time...Hope this helps good luck...

You could connect both sets of leads to one battery and get 10 Amps but you might confuse the charger. Each set of leads receives 5 Amps. I recommend talking to the manufacturer to see if that application will work correctly.

Yes but they have to be charged via the camera. That means you can charge one battery at a time while it is connected to the camera unless you buy a separate charger. So...if you are hoping to charge one battery and use the 2nd battery on the camera while the first one charges your out of luck.

Yes, two of these could be connected together. However, you may need to be concerned about voltage drop due to the added resistance. You should determine what you current requirement (amps) will be, and if it it more than 0.25 A then I would be concerned.

Supplied amperage would the question. You could charge both at the same time but it would take much longer.

This is what this device is designed for - 2 USB ports give extra power to 1 device.
