how about a powerbank with HQ solarcells that really works outdoor in the sun? With Ports like USB 3.0 / 3.1 / Lightning and USB-Type C PD
The idea keeps coming up.
The reason to not is very simple:
- Batteries hate heat.
- Sun makes heat.
You’re better off having a separate (hot) solar panel and a cable long enough to have a separate Powercore in shade.
Plus solar ages slower than do Lithium cells, so you’d have a perfectly working solar panel welded with a dud Lithium cell.
Above are the obvious reliability issues, you then have the viability issues.
There are plenty of combo solar+battery products, but either you have:
- a tiny solar panel, who’s added weight exceeds the weight of simply carrying another battery instead
- a large solar panel with battery included, the battery weight makes propping the solar panel angled at the sun more difficult.
Take for example a 20000 vs 10000mAh Powercore.
So for 154g more you carry 10000mAh more.
OK. Thank you for the detailed information.
