Ecoflow River 2 and Hb21 100 Solar panelwatt

Exactly what we need to drive the lights in our cabin, no need to wire up to the mains, lasts over 8 hours and recharges via the panel in 3 hours on a sunny day. Arrived nice and quick
Good work 😁

Excellent panels at an unbeatable price.

I have two of these hooked up running a small solar fridge, excellent price and well packaged.

Excellent Panel

I purchased some more expensive EcoFlow 100 watt panels along with this HB21 panel. This has performed just as good delivering near the rated 100w in decent sunlight. It is well made and sturdy, and best of all it is nice and compact for a 100w panel. I'm setting up a portable array for the backyard so this will be perfect given its size. I'll be getting some more.

Great panel for camping

I have been happy with this panel. I set it up with an Anderson plug so I can use it as a portable panel while camping. It preformed well and I had no issues. Sturdy construction.

100W Rigid Solar Panel

Bought this to see if would be a good temporary solution for the EcoFlow River unit I bought awhile back. Happy with the unit, managed to get good solar gain on a cloudy day. Definitely a manageable travel size and not too heavy to transport. Although I wouldnt want to use for regular travel more mid-long term setups in one location suited. Will go well on camper with EcoFlow River.
