Just depends how much your adapter can deliver.
Probably 500mA is ok (even though not all adapters are made for 500mA,
I have some chargers rated for 350mA).

1A is quite a lot. Might be ok, but first make sure that the
specifications of your charger are ok for 1A output.
(note that none of the few car chargers I have are rated for as much
as 1A output, but most of them are old phones chargers...)

I do force 500mA with an adapter I got from an older phone. I don't
have the exact specs of the charger, but it works ok.

to do that (with latest kernels) :
echo 500 > /sys/class/i2c-adapter/i2c-0/0-0073/pcf50633-mbc/usb_curlim
