How fast or what amperage does it charge AAs when connected to a USB port, say, that pumps out 2A?

The Guide 10 Plus charges the 4 AA cells at about 600mA, when connected to an USB port. It does not matter if the USB port is rated 1A or 2A.

I do not know if it can measure 2.4A, but I have pushed it to 2.24A peak, charging my Galaxy Tab 3 via solar. USB ports were never meant to deliver that much anyway... The physical contacts are really taking a beating at this amperage. It actually sparks when unplugging.

The output rating on this is 1.5 amps. Manufacturer notes, "Charge up to 2 small USB compatible electronic devices".

Generally amperage output for USB 3.0 is 0.5-0.9 mA for standard and up to 5 mA for charging devices. This may drop a bit if you have multiple devices plugged in.

The USB port outputs 5V DC, the Amps it can provide is 1A making the Wattage 5.

Yes but a bit slow, 2amp is the best and max suggested rate for most small SLA's. Any higher fast chargers will do that but reduce overall life.

I would check with Wagan to be sure, but as near as I know the output from any port is standard USB at 2.1 amps. I hear some Samsung devices have problems due to their proprietary wiring of USB.

It should be similar to your charger. If you use a two amp port it might be quicker if the device allows it. I have never timed it versus my charger.

I think this was 5V/1A output. Its a little slower than plugging it into Wall. Yes it will take longer for phone to charge on 0.5A than a 1A. There are a few chargers like Alpatronix which have 2.1A output as well.

No, the first two (5 and 10) are Watts, not amps. At 2.1A, this provides about the same power as the 10W iPad charger (multiply by 5V, which is USB standard). I have this outlet and it does seem to charge at full rate.

Most PC's and chargers limit the current to about a 1/2 amp. That's due to the USB 2 spec. There are a few, such as Apple, Kindle, and others, that charge at higher currents. I would have no reservations using this extension at 2.1 A. Go for it.

This hub is underpowered by almost 45%. USB 2.0 ports should be able to pull 500mA, so with 7 ports the AC adapter should supply 3.5 Amps. It only delivers 2. Almost every powered hub on the market seems to be similarly underpowered.

do you have anything that has more amps? im more sorta looking for a faster charger

Should be rated at 2.1 amp. Charges as fast as my Belkin charger rated at 2.1

Not positive on the exact amperage but I know it is less than 15 and plugs into a regular receptacle.

Yes, I've used a 1A and also a 2A USB charger plugged to an AC outlet. I think you can use pretty much any USB chargers, and not just charging by the computer. The speed of charge will be determined by the current passed through the device.

I plugged this into a 12V (3-cell LiPo) battery and measured current draw. It was taking 75Watts at 11.7Volts, so about 6.4Amps. In a running car the air pump will draw slightly more current, but not enough to overwhelm your charging system. If you have a smaller engine just turn off the headlights, it'll be fine.
