  • I gotta say I disagree.

    Even the best solar panels (best being lightweight, rugged, and decent output) are usually 500g without a battery pack, and then you have to tinker with it and haul it in the open.

    Real-world testing with a highly recommended solar panel, the Nomad 10W, says you can charge a 10k battery roughly every 2.5 days in “good” conditions.

    A good 10k battery bank (nitecore 10k @150g) + the Nomad 10W (500g) = 650g

    Now on day 1 with these nearly ideal conditions you’re going to have 10k mAh in your power budget

    Day 2 you have (10000/2.5) = 4000mAh solar power for a total of 14k mAh

    Day 3 you have 18k mAh

    Day 4 you have 22k mAh

    Day 5 you have 26k mAh

    Day 6 you have 30k mAh

    For a whole week you have 34k mAh.

    The alternative is you use your 650g budget to buy as many nitecore battery banks as you can afford. That’s 650g / 150g = 4 10k battery banks.

    That’s 40,000 mAh in 600g vs 34,000 mAh in 650g during nearly ideal conditions.

    Break even doesn’t happen until midway though day 9. 9 days of ideal solar conditions to break even and begin seeing a benefit to bringing a solar cell.
