@egonotto, So what is your final opinion on my selection

[suryaputhra]

Is it possible to test 96V DC SMPS power bank chargers with these usb scopes, if I use 10x probe I am pumping in just 9.6V at scope input am I right?, is it possible test such voltages with this scope, thanks in advance.

Can some one put light on above scopes.

If this is enough for you?

They have only 1GS/s for 4 channel with 250 MHz. Far too low

But they a cheap.

The software of my scope is not very stable. It crash often.
But I don't know if this is the case with the scopes you want.

You must decide yourself.

This is very dangerous!
There can be very high voltages
And the USB-scope has USB-ground.
So you need differential probes.

!!!!!!Don't do measure on those dangerous equipment before you acquire the required knowledge!!!!!
