I have a A22 for use as a backup in-flight. I seem to have lost/misplaced the charger that came with it. I'm looking for another charger OEM to purchase for it.

In the mean time .... I noticed the AC charger for my laptop fits and powers the A22 (before freaking out ..... it turned it on under AC power for less than a second.)

Can someone who knows something about battery charging / power let me know if it is safe to charge the radio with this charger, or what information I would need to see if safe?

Thanks in advance .
