Hurry, only 2 items left in stock!
Fast delivery, earlier than the specified date. The panel arrived in a dented package, but everything works.
Quantum 5 can charge for about 3 hours in a sunny living room, but it doesn't charge well in shaded areas. So, it's for charging while resting. It's okay. It can charge with a Type-C port, but the second USB port charges faster. It seems to be almost 3-4 times faster than other ports.
It arrived well, but not all are the same, only black ones were sent, even though I ordered yellow ones.

It needs to be tested, I don't know how well it actually meets the specifications.
Great value for money 👍
Visualy it looks like good outdoor solar panel, rubber like material, hopefully it will not be broken after several foldings. There is direct output of solar panels, about 20v, 2x usb a and 1x usb c, but all of them are just 5v only (no qc or pd), driven by cn3903, so 5v/3a is max output (all usbs together). Solar panels are in series, so it means all of them must be on sunlight, if one of panel is covered, output is zero. Thats bad. If it is partialy covered for instance on your bag, power is significaly lower. Also output power is almost 20w (20v, 0.9a) on direct noon sun (clear sky, no clouds). So it is about 50% of declared power. I was afraid that it will not be 40w, i do not understand these overstated values of power. I think it can be practicaly used, just there are some disadventages. Order ok, shipped very quickly, packaged in box.
