Portable Laptop Charger 50000mAh/135W Laptop Power Bank External Battery Pack for Various Notebook Outdoor Emergency Power Backup Multi DC20V/DC12V/USB5V Outputs for Laptop iPhone iPad Tablet

This is not a fault of the Poweroak unit itself, which I find to be extremely useful, just not with Dell laptops, as advertised, because Dell creates this problem to prevent us from sourcing products from other vendors. The CPU will be throttled to a barely usable level if you try to operate it while plugged into a Poweroak as an external power source.Otherwise, the unit performs well, I use a couple of them out in the field to power telescopes and other gadgets, with no problem whatsoever.

Its a great product something I was searching for a while. This product is really good to charge anything. It can charge your laptop to your ipod. Its capacity is amazing. Holds pretty good charge and deliver. I charged my laptop with this and worked great.
