Hello, I'm actually looking for a powerbank to use with my Cintiq Companion 1. I searched a lot and couldn't find clear answers. What I understand : - I need sufficient power : 19V and more than 3.42 A - I'm not sure on what I my need in term of maximum capacity : is 20000mA.h a lot ? My aim would be to let's say at least double my battery time. Today I can use it during around 4 hours on the battery (mainly photoshop / illustrator and Clip Studio, 2D drawing). If I could reach 8 hours of totla using (so 4 hours more) it would be great. More would be awesome. Then there's the question of the connector. I don't know if the Companion 1 connector is something standard. I can measure it : it's around 2.1 mm external diameter and 5.5 mm long. But is it built standard and then are the common connectors sold with the powerbanks will fit or do I need something really specific that only a few powerbanks builders will provide ? And the final thing is I'm not american... And when I find something that seems interesting, as the OmniCharge 20 for example (which, by the way, I'm not 100% sure is OK for the Companion 1), it's not sold in France. So, if someone has answers to give me, I will be very grateful Additional question : I'm thinking of upgrading my Companion in a Wacom Mobile Studio in a few monthes. Are there Power banks available ? While I love my wacom devices for their comfort and technical performances, I don't undesrtand why it's so difficult to get informations about such a trivial question of an external powerbank.
