My Device needs 750mA Max power output but from the description above I read the output currents of the the battery bank are 1000mA and 2100mA .so how can it works with my device? the higher output current doesn't damage my device? please clarify me...

This isn't a car battery with straight wires shoving into your phone like Frankenstein. I don't know what kind of "device" you have but I'm pretty sure it won't have a problem charging with this

Hello there - I am doing my own search for external power for an ASUS slider, which has the same issue of requiring 15V input. I am looking into multi-output battery pack / laptop battery packs. They are more expensive and larger than the others I have (Newtrent, powerGen), and do NOT have the 15V USB out so would need some type of conversion cable. Will let you know what I end up with and if it works. I am contacting a few of the laptop brands to see if they will work with ASUS tablet. Good Luck!RJ

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.

They are probably overrated, but 1000 mha is 1amp for 1 hour. that is how long the battery will provide 1 amp worth of energy. I would consider this rating useless as there is no energy draw stated for most electronics.

I did and I am not having any issues. The mAh capacity only affects total charging capacity of the batteries. The higher the mAh, the higher the total charge of the battery (the battery will take longer to drain out). I am not a pro, but that's what it was explained to me a long time ago. I hope it helps.

This is acute little charger. It says the maximum current output is 500 ma. That's probably at 6 volts which means the max at 12volts will be about 250 ma. Not really powerful but if you are not in a hurry and you have small lead acid batteries this works well. Hope this helps.

Yes. The amperage is also referred to as "drain". The battery will only deliver as many mA's as the device requires. A higher rating simply means it will work with higher drain devices.

Not sure about the 7000mAh. I know it doesn't do a good job on charging the 2100mAh standard. It only charged the standard battery to about 88-90%. I ended up getting my account reimbursed.

Charging voltage i beleive it depends on the QI Charger you are using. As for the output, it is 640mA. Best

The charge output is very dependent on your charger & cable. I get anywhere from 400mA to 1900mA using my old chargers and old cables. I do own 3 of these cradles because they are very good.

yes but..... The current is the max you can draw. A device that uses say 500mA will be fine on a transformer that can deliver at least that amount, so using an 800mA transformer will be fine harder the other way around if device draws more power

Nope, 5 volts output at all times. Devices are usually designed to swap to a trickle charge once the battery reaches a certain level. Also with lithium and metal oxide batteries memory affect is not that big of a concern.

Hi William: If you need stable 12V power, you may consider our BP160 battery, which has 12V and 5V USB port. However, BP160 5V USB port maximum output is only 1A. Best regards. BiXNet

The answer to your question depends on the output voltage...however from the back of the device it says 70WH (watt hours) max so you can calculate MAH from that.

I believe the charging circuit monitors the voltage and as the voltage reaches the maximum for that type battery the charging stops. The lights turn from red (Charging) to green when fully charged. It is recommended to take the batteries out once charged and use them. If its not a device I have to have I just take the dead batteries out and charge them and put them back in. They charge quite rapidly. If the battery is bad it won't charge them. I love it, especially the dual usb chargers on the front. I can quick charge my phone with the 2 amp or leave it on all night with the 1 amp. Per your question no, I don't believe it will overcharge a battery.

It does 5v through the USB connections. It does 9v or 12v (selectable through a toggle) for the round output port. The 10000mAh is the amount of power it stores. My phone (The Note 3) has a 3200mAh battery and I have tested it can charge it from low battery (Any where from 1% to 5%) to full about 3 times before it needs it own charge. On a side note it charges what's connected faster than it charges itself from the wall. So two 5v devices will drain it quickly and without being plugged in it won't charge two 5v device it shuts off.

The specs on this device calls for 5V 1.5A power input. As long as the supply you have is also 5V, you can use anything capable of producing at LEAST 1.5A. Charging with a supply greater than 1.5A capacity will not hurt your device. I hope this answers your question. For an analogy, think about car batteries... More Cold Cranking Amps (CCA) will not hurt your car's starter motor. It's more capacity that may never get used.
