hi,

I'm after a smaller/lighter adaptor for my thinkpad. The
laptop is rated at 16V, 3.36A. There's one that I'm
looking at that is rated at 16V, 2.2A. It also looks
a fair bit smaller. What I'm wondering is, can I safely
use it with my laptop?

I get about three hours use on a 3.1AH battery, so the
actual current consumption is nowhere near 3.36A I'm
assuming. It also takes quite a long time to recharge,
so the charging current can't be too high either.
Apart from the coax power plug which may be different, is
there anything i'm missing out?

it's a thinkpad 240x, the adaptor's for another thinkpad.

thanks!
