Use an external battery

Hello, I recently bought a Yoga 730-15IKB and I wanted to know if it is possible to use an external battery to power the PC.
I tried with a Ravpower battery with a USB-C port but it does not seem to work.
Thanks for every suggestion

Re: Use an external battery

Don't know much about Ravpower, but if it doesn't offer 20v (check the specs of the specific model), it won't work. These things won't charge with ordinary 5v battery packs and adapters. Gotta have one that'll do 20v. Even then, you may need to try a few as it seems USB-C device makers don't test their products with everything and the whole USB-C standard is still a bit ...fluid.

Lenovo also has a USB C laptop battery pack: https://www.lenovo.com/us/en/accessories-and-monitors/chargers-and-batteries/power-banks/USB-C-Lapto...

Re: Use an external battery

@gigiusia,

 

Which Ravpower unit did you try?  I looked at the XTREME 26800mAh specs and it says 20V @ 1.5A.  That's 30W.  The 730 is shipped with at 65W or 90W power supply.  The Ravpower may not provide - or negotiate - sufficient wattage.

Re: Use an external battery

I got a glare, the output of the power supply is 20V-4.5A and certainly can not work with my charger, thank you very much.
