On Monday the electrician will be here to upgrade my electrical. I work from home and the power will be out much of the day. My work laptop is a Lenovo Thinkpad (I hate it).

I have a couple power banks. One is 15,000 mAh/55.5wh, the other is 20100 mAh/ 72.6 wh. They both only have USB ports. Will these charge my computer? What sort of adapter would I need?

Thanks!

I’m not aware of a full sized laptop that can be powered by USB. I believe the USB standard is 5v at 2 amps and that won’t be enough to power your laptop.

That’s what I was hoping wouldn’t be the answer. Maybe I’ll take a PTO day.
