Hey @gerdisch1 Depending on your needs ie portability vs. off the grid solution the size of the power bank and the size of the solar panel that someone might suggest will be different. For a small scale solution take a look at the Sherpa 50 or Sherpa 100AC power bank that can be charged with a Nomad 14 plus or 28 solar panel. If you give more details about what you’re looking for (type of computer or other devices you might charge), where you’re taking the power bank, the conditions you’ll be charging it in (in SE Alaska solar charging takes a really long time) we might be able to give more helpful advice.
