Why this Renogy product
High portable output without a rigid suitcase frame
Compact storageThe blanket folds into a backpack-size package for trunks, vans and limited storage compartments.
Flexible placementLay it on the ground or a vehicle, hang it from supported points or reposition it as the sun moves.
N-Type cellsRenogy markets 25% cell efficiency and strong low-light/high-temperature behavior for this portable format.
System fit
Match the electrical input—not just the connector shape.
The 400W blanket is rated 33.6V Vmp, 11.9A Imp, 39.2V Voc and 13.1A Isc. An adapter that physically fits does not prove electrical compatibility with a controller or power station.
Power stationsConfirm the station accepts the blanket’s Voc, operating voltage, current and 400W rating, then use the documented adapter.
Battery systemsUse an MPPT controller and correctly sized battery-side protection. Never connect the panel directly to a battery.

Common questions
Buyer FAQ
Can it charge a portable power station?
Yes, when the station’s PV input ratings are compatible and the correct adapter is used.
Can it charge a 12V battery directly?
No. Renogy states that battery charging requires a compatible solar charge controller.
Why is real output below 400W?
The 400W rating is measured under standard test conditions. Angle, heat, shade, dirt, wiring and conversion losses reduce real output.
Does the 400W blanket include USB output?
Renogy states that only the 200W blanket has a built-in USB output; do not assume the 400W model does.
