WHY IT
100W that folds away.
Into its own bag.
The S100 is FlexSolar’s single 100W folding panel, with USB-A, USB-C and a DC output for a power station.
Monocrystalline cells
FlexSolar lists monocrystalline solar cells.
USB or DC from one panel
USB-A and USB-C for small devices, and a 20–27V DC output (up to 100W) for a power station. The ports share whatever the panel is producing.
CHECK THE FIT
What it charges.
And what to check.
The Anker SOLIX C300 DC
Its DC output (20–27V, up to 100W) sits inside the C300 DC’s solar input, which Anker lists as 100W at 11–28V with an XT60 connector. The S100’s cable includes an XT60 plug.
Check voltage, current and polarity
FlexSolar says to confirm your device’s accepted voltage range, current limit and polarity: a plug that fits doesn’t by itself mean it’s compatible.
Not for running a Starlink Mini directly
Its USB-C port gives up to 45W, and a Starlink Mini needs 100W from a single USB-C port. Charge a power station with it instead, then run the Mini from that.
It doesn’t store power
The panel itself stores nothing. Pair it with a power station or power bank to keep power for the evening.

WHAT IT HAS
The outputs.
And what comes with it.
USB-A and USB-C
USB-A at 5V/3A, 9V/2A or 12V/1.5A, and USB-C Power Delivery up to 45W.
One cable, four plugs
The 2 m adapter cable ends in Anderson, XT60, DC7909 and DC5521 plugs, so it suits many power stations.
Lay it out or hang it
Open it flat on the ground, or hang it from its hanging points with the two carabiners.
In the box
The S100 panel, a carry bag, two carabiners and the 2 m four-in-one DC adapter cable.

QUESTIONS
Good to know.
Before you buy.
Will it charge an Anker SOLIX C300 DC?
On the makers’ figures, yes: through the XT60 plug, its 20–27V, 100W DC output is within the C300 DC’s 11–28V, 100W solar input.
Will a USB port give 100W?
No. FlexSolar says the 100W is the panel’s rated peak under standard test conditions, not the output of each USB port.
Why will it make less than 100W?
Sunlight, shade, angle, temperature and the connected device all affect what it delivers, FlexSolar says.
Is this the two-panel kit?
No, it’s one S100 panel. FlexSolar sells the two-panel kit separately.
