Will this charge my One without wrecking it?

while debating whether to get a charger from ebay for 15 quid, i noticed that my digital camera charger was not being used. i flipped it over and saw that it powers 5.3 volts, which is 0.3v over the reccommended power.

is this 0.3v too much? or will it do the job?

many thanks for your help

anything with up to 6V/2A output, with a correct jack

Over 2A is not a problem, but below 0.7A might be. Check the jack polarity as well (just in case) if you have a voltmeter. But if you are not sure what you are doing, get yourself a proper TomTom mains charger.

it says 650mA after the 5.3V will that be enough?

sorry i dont know all that much about this, its be awhile since i did it in physics

it will charge the unit, but it is safer to use a proper TomTom charger.

Charging requires a certain current profile If the battery is nearly discharged the initial current flow can be quite high, so your unit will be demanding (say) 1.5A from the charger. The charger will be limiting the output to 0.65A. Depending on how the charger is designed, it might become overheated or damaged. The correct profile for charging the battery in the unit will not be followed either. I'm not sure if it will shorten the battery life or otherwise damage it, but it is simply not worth the risk.
