Greetings from Portugal. I'd just like to say that i've found a powerbank that can be used with the 900s (and probably others that use the same charger).
The one i found, and can confirm charges the laptop, is "RAVPower 27000mAH Powerstation" that i found on amazon.
It's a powerbank with a regular power plug to connect the charger, so it could be called a mini ups instead of a powerbank.
Hope this helps people looking for something similar.
