Yes, that's exactly how it works. You can plug any regular appliance A/C cord into the unit and it will run it as long as the appliance is not too energy hungry (i.e. < 100 watts). This is a great portable unit and I highly recommend it.
1996381
Yes. But consider what you are charging. It isn't powerful enough to charge my MacBook Pro. It's more for phones/ipads/e-readers.
1996382
It should, but I would check the wattage to make sure the charger doesn't damage the battery.

I also would not recommend doing that. On a 2 bank charger there are 4 connections 2 pos. and 2 neg. connecting all 4 to 1 battery would not be possible. If your device calls for 1 battery purchase a 1 bank charger.

Hi, I believe you'll need to figure out what the amperage is of the power supplies that what you want to run and if anything else is running on the same circuit. I read in the reviews and elsewhere that you should use this accessory with a 15A or less fuse, so I have it on a circuit with 15A in my travel trailer. My laptop 12v power supply uses 3.5A, the Coleman 12v cooler uses 5A, the phone charger uses 1.5A I think. I have run the cooler and a charger at the same time without it melting or blowing a fuse. I did fry the last dual power outlet (different make, felt cheaper) with the same usage (Caveat: I am not an electrician and am just sharing my experience.)

the batteries are not a problem. Some AC chargers for recharging batteries will work and some will not. Let me know the wall charger you are using and I will let you know. Most wall chargers will work. They need to be switching type that most are and less than 10 watts. Ken

Yes you can but, if you are using a wall charger to charge the portable, you should probably use the wall charger to charge your unit instead because it would be faster. And it wouldn't drain the life of the portable battery either.

Yes, you will be able to use this as if it is plugged directly into the wall. It will not only power it but also charge it slowly while you are using it.

I think you'd need an adapter to use it on 220 volts. Electricity is not my area of expertise, but I plug mine into the U.S. standard 120 V outlet; I know that when I travel to countries that have 220 V, I have to use an adapter on typical appliances. I would assume it's the same with this charger. Update: I just looked on the part you plug into the wall, and it states "Input: 120--240V" --so perhaps this device will handle 220V! Good luck!!

now i don't think sow , it's not really 2 power something , it's more like a battery charger , but it is good quality, try 2 put a battery between it , than it might work .

I would recommend researching the power converting to ensure it meets your needs. I would not want to answer incorrectly and mislead you since I am not a technical expert on the converter. I had purchased it to use for a China trip. If I don't sell it, I will most likely keep it for upcoming travel. The reviews I have read have all mentioned it being a great converter in many different countries.

You can use both. The item only comes with a USB cord but, if you have one of the wall chargers that accept usb you can charge it that way. Like this one: http://www.amazon.com/Cable-Wireless-Travel-Charger-Adapter/dp/B00CTTD10Q/ref=sr_1_2?ie=UTF8&qid=1385925090&sr=8-2&keywords=usb+wall+charger

I'm not sure I understand your question but it seems to me you're asking 1) Can this unit charge your laptop battery via a USB port on the laptop? I don't think any laptop allows you to charge its battery via a USB port.2)If you are asking whether or not you will able to charge the batteries of other devices by routing power through the laptop's USB port into the WASABI charger's USB port then I don't think so because the USB port on the charger is listed as an output port.

Yes it will work. You just need to unplug the USB end from the wall plug and use the USB portion only. I haven't tried a full charge but it definitely gets you through in a pinch. It is a very handy device to carry with you at all times, I even use it to charge my cameras. That has been a real lifesaver for those special moments you don't want to miss because of a dead battery. Give it a try I think you will agree it comes in handy just when you need it most. TC

Do not quite understand the question you ask. however, the device can be plugged in from another source provided that delivers the voltage and amperage specified charger with the same original plug. The main problem is that it requires 2 amps to work.

That is a good question. Do you mean a plug into the wall type of charger that is used for charging cell phone batteries? If your answer is yes, then as long as the battery fits in the charger properly, there is now reason that it shouldn't work.

I use a usb charge stick. The kind you would use to charge your cell phone or tablet when away from a wall outlet.
1074883
yes you can, but I have only done it on USB 2.0 or a usb wall charger of at least 1.0 amps.

It is not a function of this portable charger whether you can use 240V or 120V to refill the charge. That 120/240V wall plug is not part of this device. Basically, you need to buy a high power USB wall plug that can plug in the wall of 120V or 240V. Then you plug the USB cable which provide with this device to the USB wall plug to get the charge refilled. You can use any USB port to recharge this this portable charger (battery). Some are faster and other is slow. Computer USB port is among the slowest. Buy a wall USB 120V/240V plug that delivery 3A of capacity is what you looking for.
