Can 2 (or more) 'Wallwart' AC Adapters be used as a battery eliminator for a Laptop? Answered
Right, my sister's laptop has suffered the classic 'dropped on its power socket' syndrome...
Now, I know there are Instructables on how to repair/replace it, but I can't find anything that'll handle the DC 19V 3.42A the adapter gives out - and I can't match the numbers printed on the socket to anything on RadioShack, to get an exact replacement.
So, my sister is left using only battery power (which I charge in my same-make laptop) which rarely lasts 1 1/4 hours.
Anyway, down to the nitty-gritty: The battery gives out 10.8V, 4500mAh, I saw pir8p3t3's 'Reuse "Wallwart" Adapters' 'Ible, realised I have quite a few mobile (cell) phone chargers - and got to thinking...
Now, I know that a straightforward parallel connection (would that be safe, anyway?) would require some way of stepping-down their combined output voltage, but would there be any safe way of reaching (let alone exceeding) that 4500mAh?
Or am I just barking up a too-dangerous tree?
Any suggestions would be welcome. Thanks.
