Looks like my Vision Spinners that I have here.
Even if it was a clone, the battery is probably the same
in a clone versus the real thing. As indicated, they take
shortcuts on other stuff with the device - such as cheap
aluminum threading that will probably strip in a couple
of months time (I put an adapter on it stat), or wobbly
buttons etc. Recently I had a clone that first the little
wheel that you adjusted volts would stick and I needed pliars
to change the voltage. Soon after that it stopped holding
a charge (lasted about six months, rip). But highly unlikely
to blow up if you use a proper charger on it, clone or no clone.
