8 * 1.5V, OTOH, is 12 V; the maximum voltage permitted is 9.3V, so this would be outside the charger spec and potentially harmful to the device.
Edit: Oh, and your calculation is wrong; the capacity in Ah is the same as for one cell, since you connected them in series. You don't pick up any by reducing the voltage with passive elements; the extra energy dumps as heat, so make sure your resistor is rated for the resulting power. (9W, if I calculate right...)

I bought the Philips in a Media Markt (400 shop in Urop).Don't know about the UK.

It's part of the "Philips power2go" range. I also don't see it anymore in the US / UK Amazon.

Succes, Abel.

If the n8x0 device line is "so old mobile phone"
then you're using a typewriter to post this....

since a typewriter isn't a computer.
and a n8x0 isn't a mobile phone.
