>>2216159Next year when I'm gonna do some long bikepacking trips I'll combine a 28W BigBlue solar panel with a DUAL INPUT powerbank (probably an Anker PowerCore 26800 mAh).
The dual input function is important in this case because it allows you to use the two USB ports of the solar panel to charge the same battery so it takes less time to charge.
Right now for my 2/3 nights trips I'm using two 22000 mAh Ravpower powerbanks, one would probably be enough for simple hiking but since I'm bikepacking my phone is almost constantly running the GPS at full brightness + I'm taking pictures and videos + the battery in my phone is getting pretty old in the first place.
