powering laser from inverter

[norty303]

Anyone had any experience with using the new breed of mobile power banks?
I've just bought a 70000mAh unit for starting my 2l diesel car, and I'd think it might do lasers well too. It already has outputs at various voltages for laptops too. I paid less than £40 for it as well.
And its about the size of my hand.

I was thinking of getting one of these as well,....but decided to wait until someone here can confirm the "real" capacity these things have, after a few "re-charges".

Have you tested yours yet

Cheers
PS. That's a lot of zeros there....why not call it 70AHr?

Because bigger numbers are bigger so must be better

I have to admit that HMRC seem to agree with that reasoning!
