Does the output voltage automatically adjust to the input voltage required by the device you are charging?

Yes, within reason. for example, an iPod, iPad, and IPhone all have somewhat different input voltages, yet may all be properly charged by the RavPower Xtreme. Not sure it could charge a power drill.

Both USB ports are 5V, one at 1.0 A for iPods and phone, e.g., and one at 2.5 A, for tablets, e.g. The DC port output is variable, at 9, 12, 16, 19, and 21 Volts. Select whichever your notebook requires. If it falls between two #'s, choose the higher. The manual has good documentation.

No. You need to find the voltage output on the charger for your device. Then you will have to adjust the output on portable charger by holding down the power button for a very long time, and then adjust it to the appropriate output. The instructions are in the manual.

I just checked my charger and it has the input at 120V NOT 120V-220V. So I would say no, unless you use a transformer.

no, just the rate of charge-then drops into a fully automatic maint mode-a really nice charger

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.

The unit I got was preset to 11.99 volts output. I used a voltmeter to set it to 12V output. The input accepts a range of voltage and does not need to be set. I connected my 20V and then 12V rechargeable batteries and the output voltage did not waiver.

No. When you plug it on it is automatically on. There is no adjustment either.

Looking at the charger now it's specs read output 5.7v. 800mA. And yes USA plug config.

I agree with Cpk voltages will change constantly, but I would still confer with the manufacture when possible. My charger charges at 4.2 volts with no problem.

yes, but you will need to purchase a voltage transformer or another charging cable.

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.

Make sure you're using the input USB. Should charge automatically. You only have to turn the power on to use the device for charging purposes.

My guess is no, but we will see if anyone answers my similar question. I cannot currently get the device to charge and discharge at the same time. I plugged it into my phone when I got it, and I think it might have drawn power FROM my phone.

I believe it will. It's rated at 20 watts and will adjust to which ever device is being charged.
505955
Yes it does. The power supply can automatically handle different voltage sources

All 4 of my chargers are set for 4.2v.I have had NO problems at that setting But, always charge new batteries as soon as you get them.I charge all my batteries, any size in it.The charger is automatic , stops charging at the correct voltage.George

Yes that's the neat part of this device there's a tiny gold screw you can either adjust to go up or down in voltage just hook it up to a multimeter and set it to the voltage you want.

I'm changing my answer. The answer is YES! Mine is charging now after I put the power switch in the correct position. Sorry for previous response.
