When internal batteries are removed from tablets and notebooks

[meanie]

Can one power it directly with an AC adapter? Like the good old days?

I've been able to on a variety of devices although it's not recommended because it could damage your device if there is a high electricity load. And if you do it then don't mix charging cables. Only use the original one.

Would using belkin surge protector help?
Would you mind listing those devices?
