No longer completely wireless but anyway portable.

Annoyed by constant flat battery for my power tools , few years ago I did convert some to use external power bank.
Lithium battery from my electric bike 24v 10-20Ah require now to recharge only few times a year.
Some of my drills come with 2 NiCd batterries and already dead- so I removed battery and soldier an 2m extension cable with cigarette lighter plug.
Cigarette lighter socket is attached to battery.
Small inbuilt electronic controller allow to set-up any voltage from 0 to 24V

Now I can work as long as I want without worrying about flat battery. Drill is even lighter to handle without battery, just need to carry this battery bank near to the work place.


I suppose the future for all battery tools is now additional plug and cable the could connect any tool to small battery bank. Tool is still portable and never will run out of juice.


I still could quickly disconnect cable and put standard battery in place, but for work that require more and longer work I could use my portable battery bank.

Carrying that heavy battery pack around all day would be a pain in the azz.
Would need a heavy duty tool belt to carry that load.

I think he said it is lithium (ion), so it should be relatively light.

I just keep a power point close by - seems to work OK and dont need expensive battery operated tools - and the extension lead doenst weight 6kg !
