I have just purchased one of these and it goes well for what I want it fo. It came with a USB charging cable and I am little lost on the charger I can use? I have fast chargers with my smartphone, can I use that or is there another charger I need? I bought it on line and did not go and get it in store. So can anyone help?

If it came with a standard mini USB charging cable then any phone type charger will do. Higher Amp rating will charge it faster. All USB chargers are 5V but the Amp rating varies. You can't 'overamp' a device when charging it. It will only draw what it can. So a higher Amp charger is fine. Higher Voltage is NOT fine.

A 'fast charger' may have special wiring and or special cable so it fast chargers you phone. Hubby's Oppo has this. However that charger/cable is still perfectly fine to use with any other device.

So how will I what voltage for the Wonderboom2 is too high? Or if I get it its own Samsung Fast Charger (these are the travel adapter type ) will that do the trick? I do have a cable that came with the Wonderboom2. My phone charger has an output of 2.0A, I do have a Belkin charger which has 2.1A and is 10W but that can be quite slow. I certainly want to be able to charge it and do it correctly so I do not inadvertently damage it while charging it.

Don't worry about the voltage. It came with a usb cable. This means it's use a standard 5v usb charger. That's ANY phone charger. Higher Amperage will charge it faster. Lower will be slower.

Thank you everyone for your replies. Dumb question I know but had I got it at in store I would have asked them ;-)

Google often has answers but they can be difficult to sort from the crap.

No, that's not quite right. Fast chargers support higher voltages through USB , 9V and 12V incrementally. The device however needs to request the higher voltage, I.E be a fast charge capable unit, in the absence of which the charger defaults to 5V.

If your charger has a higher current rating it will make no difference, the charger will only supply as much current as the device being charged draws. I.E current isn't "pushed", it's "pulled"

So if your device has a charging circuit in it designed for 1.5A and your supply can provide 2.0A your device will only draw 1.5A from the 2.0A available.

Ohms law, voltage = current x resistance.
The resistance is in the device being charged and is a fixed quantity,
the voltage is fixed at whatever the charger supplies,
so the current must vary to accommodate the other two.

5V=1.5Ax 3.3ohms in your device
or
5V =2A x 2.5 ohms in your device
