Does this battery only charge via direct current? What does "Input: DC 5V/ 2A" mean and what type of power adapter is this?

The input is a 2A micro-usb to charge. It comes with one, but the iPad 3 wall blocks and computer USB ports work too. It has two outputs, one 2.1A USB (for tablets and Raspberry Pi and high-current devices, the other 1A USB for phones and smaller devices.

Yes it has to be charged only by a direct current transformer which is provided. DC 5V/2A, means that the input voltage, to recharge the battery is 5 volts of direct current. 2A is the amount of amperage that is suggested to recharge the battery. This dose not mean that a transformer of lesser amperage won't charge it it would just take longe. Think of amperage as a pipe the larger than amperage the bigger the pipe.

According to the enclosed booklet that comes with the charger the output voltage is "5 volts DC"and the input voltage is "5 volts DC, max 1 amp" hope that helps you out.

It's actually the DC output to the device from the AC adapter that you want. It is 5V at 600mA. The plug-in tip polarity is positive inside, negative outside.

The output voltage on the charger I have is 2.8 amps DC (nom 2.8 A---) whatever that means. I have a 12 volt battery and so far it's working fine for me. It is a 1 hour battery charger. Hope this helps, Duane

I would look on your original charger's electrical specs and make sure the numbers match. With most chargers I've ordered, they have worked if I did that. This charger, however, was mis-advertised. It says it is a DC 5V 2A, but it was in reality a DC 5V 1500mA, which didn't work on my Android tablet, so I had to return it.

From the spec sheet...USB Output: DC 5.2V 2AmpUSB Input: AC 125V 50/60Hz 350mA

Let me start by saying that so far, I've only connected this power supply long enough to verify it wasn't DOA. However, I'm an electronic engineering technician by trade, and have done some DC power supply design and prototyping. Generally, whatever voltage the battery or other DC power source provides is further regulated and conditioned before being passed along to more sensitive, delicate circuitry. So putting out 0.4V more, or having a bit of 60Hz ripple is very unlikely to have any effect at all on the camera. Solid state electronics usually operate on 5.v, 3.3V, 2.V, or 1.8V, each with a tolerance of 5% or more. Typical lithium cells seem to be nominally around 3.6V (or 7.2V for two in series). The charging of all lithium cells is carefully managed by elaborate controller chips, so I wouldn't worry.

Well, all I can say is that I use it with an Anker battery pack, which says 1.5A input current.As far as I know these new chargers, which output via a USB connector, establish sort of connection with a device being charged. And the device itself will only take whatever it is capable of.So it's not like the charger will shove those 2Amps down the device's USB connector.Your device is supposed to support whatever current is listed on the device. Otherwise it will just use as much as it is capable of.That's what I've been told.Hope this helps.

My unit was shipped with a 12V DC 2A power supply. Power connection is a 5.5mm jack. Mains input on this power supply is 100V-240V 50/60Hz with American 2 flat pin connectors.

I do not own a DC adapter for it at all. I have been using solely battery power. Thanks

What is the output voltage of the charger? Is it ac or dc. I suspect it is 12vdc, pin + but we have miss placed our charger and would like to get a new one. Thank you.

I had the same problem. So, I tested the battery with a multi meter and it tested at 4 volts dc. That was the condition it arrived to me in. I tossed it in the trash and bought an equivalent from RADIO SHACK. It tested at 12.3 dc volts. I hope this helps.

I have no idea. I have only charged the battery using the charger that is plugged into a 110 Volt outlet.

Its battery is charged by AC adapter. Disappointingly, its AC adapter is for 110V only.

This battery is rated at 4.5 amps according to the description. Generally, matching voltages is more important than matching amperages, but laptops chargers are pretty versatile. My laptop takes 19v/4.5a but it will charge with a 16v/3.5a, though more slowly. Your laptop would most likely work fine with this battery. I haven't seen any external batteries that offer 4.7 amps - 3, 3.5, and 4.5 amps appears to be standard.

I did not notice that either... my best educated guess would be that it can charge up to 8.4v, but will also be able to handle the 7.2v by automatically charging at a lower voltage... i could be completely wrong though... i bought this kit a few months ago for a sony handycam that i bought to record my engagement. the charge on the batteries lasts a long time! even if the charge hasn't been topped off recently. i charged both batteries when i first bought this and really only used and recharged 1 so far. i decided to pull the 2nd one out of my bag pocket and it still had full charge. it had only been like 2 months since it was charged last, but it was still fully charged... hope this helps.

your original charger works. the ac adapter connects to your computer, not the battery pack, unless you have some kind of external charge dock for the battery that i've not heard of..
