Can it charge both batteries at once?

No. One at a time. But you can charge one with your GoPro via USB while the other is charging on this device.

No. It charges one battery at a time. It's pretty basic, and I am very very happy with it. The included cigarette lighter adapter is nice too. I've had mine for about a year and all is good so far.

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?

yes you can charge one at a time. just be careful when you put it in, it can fall out easily.

Yes, it can charge one AAA, one AA, one C, and one D if you want at the same time. If you just have one battery that needs recharging, you can do that also. I love this charger. I've had it for about a year and it been great.

Yes and you could charge an 18650 and an 18350 at the same time with both ports. I've done this dozens of times.

Hi. It charges two batteries at once but they must be the same type (AA or AAA). It won't charge with just one battery in. Hope this helps.

Yes it can...Amazon sells the two battery set with charger. I bought one and it works great.

Because two batteries charge at close to the same rate, and are not identical in their depletion, the charger stops charging the first battery that's full, charging only the one battery that's left. Sounds like it should be able to do only one.

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!

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.

Not when the pocket port is completely dead but once it has at least 1 bar of power then yes you can charge both at the same time.

Yes, but you can't charge both at the same time. The device only comes with one lighting adapter. I think you can order more.

yes, the two batteries are linked together with a jumper. Both batteries are charged at the same time, very cool.....

Yes, it can charge both devices at the same time. I don't have any information, though, about charging rates in that situation.

Yes - Connect the batteries to the charger in parallel. [The plus (+) from both batteries will land on the load + terminal. The negative (-) from both batteries will land on the output load minus terminal.]This is a very common configuration. You can put as many batteries together as you like in this pattern.Doug Wingfield

You can charge two batteries at one time. The picture is very misleading. The picture appears that the four batteries are actually connected to the charger but what you are seeing in the picture are the four batteries touching the side of the battery charger.

Yes. It does. You better have some darn bright sun if you plan to charge two devices at once. My advice, just charge one device, then the other. You will be a much happier camper.
