Will it charge a VeryKool S401?

As long as you have a cord that plugs into a standard USB port, I am sure it will. Just FYI, the charging port (micro-usb) on my delaminated after about six months and I had to tear it apart to fix it. Without that it still charged by solar, but wasn't as functional as I like.

Not sure what a VeryKool S401 is, but you can charge the batteries by your computer, but do not expect to charge the batteries via the solar panel.

At 40 volts DC I am unsure of. I can assure you of 30 Volts DC it will work well with. Incoming voltage (DC) is supposed to be higher for charging.

It will charge anything that plugs in via a USB, so as long as you have your charging cable then yes it will.

I brought it to use with my Samsung s2 .. s3 and 4 and it would not charge none of them. I am going to send this back

Yes. I checked the number on our 40-volt batteries and it is the same. We have used it to charge both the 36 and the 40 volt.

Looking at my charger that came with my S4 it looks just like this. Looks aside, it is printed on the charger that came with the S4 that it outputs 2Amps at 5V. Therefore, even if this is not the exact model it should still work just fine with no damage to the device (hence same output).

I don't have the answer to your question. I only use my charger with my SYMA S107G. Best to contact Extreme tech support for further information.

No reason why not.It will charge any Micro-USB, Apple Lightning, or device with a USB to device charge cable.Your S4 should be Micro-USB, so the easiest quickest charge is to pull out the Micro-USB cable and attach to your phone - it will turn on the MyCharge and start charging.(The Lightning and USB outputs require a press of the power button to turn on charging.)

Probably not. It is a small charger. Be aware that the charger displayed on Amazon's web site is not the model they will be sending you.

Yes it will, charge is not that quick as when you have it connected to the outlet but yes this will charge your Galaxy S4.

Yes it will. I bought one of these some time back and it charges in my DC1290A charger.

I'm sure that it would if it ever worked. I have contacted amazon 2 times and filed a complaint about the condition of charger when it arrived. I have yet to receive a response of any kind

Yes it will, I put one on my camera and it works just fine in the docking station to charge.

I'm using it on a T420, so I would believe it would work. You can double check on your charger/computer. It's output is 20V and 4.5A, which was the same as my original T420 charger.

This is a universal usb charger but I'm not sure if it works for the same outlet on the Samsung s4.
