Better replacement charger that will allow the Hi10 to run 24/24?

The Hi10 Air comes with a 5V/2A charger that is clearly not powerful enough to keep the battery charged when the tablet is being used.

Has anyone found a charger that does allow to do this, so I can keep the tablet on? How about this one?

Hello, I read from XDA forum there is a guy who use a 2A charger for this tablet and destroyed his battery. The tablet by default should use 5V/2A charger.

Can you share your experience, how long have you used this charger, and is your battery OK now?
