Charge 3310 with a charger with a bigger voltage

[Mr Wolf]

Just wondered: is it dangerous to charge for example a 3310 (whose charger ACP-7, if I well remember, has a voltage of 3.7 volts) with a charger with a bigger voltage, for example ACP-12, whose voltage should be 5,7 volts?
Or it just charges the 3310 faster?
And, viceversa, is it dangerous to charge for example a newer phone like 6230i (charger ACP-12) with ACP-7?
Anyone knows?

Hi,

>> is it dangerous to charge for example a newer phone like 6230i (charger ACP-12) with ACP-7?

I prefer charging my 6230i with the old 3310 charger.

I would not risk charging my old Nokias with the new charger.

But I dono why.

But, doesn't it take much more time to charge the 6230i with 3310 charger?
With its charger ACP-12, it's pretty fast, it takes about 2 hours.
