I just want to keep phones and small electronics charged.
You do not need a giant solar system for this job. Keep it simple: store the power in a good battery, then use a separate folding panel when you need to make more.
Anker 737 Power Bank
24,000mAh · up to 140W USB-C · 2 USB-C ports + 1 USB-A
This is enough battery and output to be useful for phones, tablets and many USB-C laptops without stepping up to a full power station.
A 20–30W folding USB solar panel
Aim for roughly 20–30W for phones and small electronics.
This is the piece that turns a regular power bank into a renewable outage setup. More panel surface gives you meaningfully more collection than the tiny panel attached to most all-in-one “solar power banks.”
We own and like the BLAVOR PN-W05 as a useful emergency gadget, and its built-in solar gives it another way to collect some energy. But a pocket-size solar surface cannot collect sunlight like a real folding panel. Buy an integrated solar bank because you like the complete gadget, not because you expect its tiny panel to replace a larger solar charger during a multi-day outage.
Need more than phones and small electronics?
Stop adding little panels and batteries. Once you are trying to run a refrigerator, freezer, several laptops or household appliances, a proper power station is the cleaner solution.
