Can it charge the batteries inside or do you have to charge the battteries on a seperate charger?

If you're referring to the AA batteries, this device doesn't charge them at all. It just basically transfers power from AA batteries you buy at CVS or wherever to your phone's battery

AA batteries provide the power to recharge your cell phones. The number of recharges depend on the capacity of the batteries in the charger. But it works in an emergency situation. I use it when my cell phone gets low on charge and I'm away from another means of charging.

There should be a voltage regulator to try to regulate the voltage to 5 V (from a possible 6 V total if we put alkaline batteries into it) so I don't think it's a good idea to try to charge the batteries without removing the batteries from the compartment. Therefore, I always charge the batteries on a separate quick charger. Since I use it only as an emergency backup charger for my phone, I only take out my Energizer NiMH batteries every few months just to replenish the leaked charge if I haven't used it for a long time. Sometimes, when I am short of four AA batteries for my other devices, such as my TV remote control, I just pop these 4 out to temporarily use them for my other devices before I have a chance to buy new alkaline batteries for my other low-drain devices.

No, the charger is included and charges the internal batteries by pressing the charge switch on the keypad. Manual does a good job describing this.

You have to hook up battery's in a series. It will charge 6 / 12 volts at a time.

It can charge batteries. There is an included AA and AAA charger. But it is cheeply made. They charge from the 12 volt rail. You can go online and find multiple 12v battery chargers for what ever you need.

I did try doing just what you described because that sounded like a really nice feature if it would work. UNfortunately, no you cannot use a charged battery in the charger to power another device.

This only charges the battery placed inside. It has a slot where you can place the phone and use it as a stand but it won't charge the phone. I find that it charges the extra battery quickly.

As far as I know you can power it with a USB but not charge the batteries. I occasionally use a stand alone, rechargeable power source for mine.

No-It appears to work by an automatic switch. When plugged in battiers off-[unless you have rechargeable batteries-then they are charging]-other wise the regular batteries are bypassed when it is plugged in. Michael Barnes

I don't have a seperate charger for mine, I just use the laptop to charge the battery. I don't know if they make a seperate charger just for the battery.

Batteries don't really work that way. The charger will fill the batteries to whatever level the batteries are capable of holding. The charger will not bring batteries back from the dead, as dead batteries will not hold a charge very well or long.

You can charge 2 or 4 batteries, but they must be charged in pairs. You cannot charge 1 or 3.

There is no separate charger. The lithium ion battery is inside the unit and all you use to charge it--is the power cord. I hope this answered your question.

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.

Not sure I understand the question, but if you mean can it charge two batteries at the same time, the answer is no. That said, it charges quickly and it has not been a problem doing them one-at-a-time. Great charger!

No, it charges with the usb cord. I bought a separate charger and two batteries for $18.00 on E-Bay.

There is not a separate battery charger, but there is a usb cable that plugs into a computer that charges it.

The charger is designed to charge both aa and aaa batteries, in multiples of two. I don't know for sure if you can comingle aa and aaa batteries for charging at the same time.
