Solar Panels for RV Battery, BigBlue [MPPT Technology] 120W Portable Camping Solar Charger with Kickstands(2USB+DC+60W PD Type C) for Lead-acid, Lithium-ion, LiFePO4 Batteries, Laptops, Cellphones

Misleading wattage. It will NOT put out 120 watts on the DC jack, for example to a Jackery battery.Max output so far is 40 watts. That is in full sunlight, angled to the sun, 70 degrees temperature. I’ve measured over several days and it has yet to exceed 40 watts on the DC jack.It may offer a greater combined wattage if you use the USB ports and DC jack at the same time. But that is not what I bought this for; I bought it for charging a portable “solar generator.”For this wattage I could have bought a smaller, much more portable panel.EDIT: I connected two Anker batteries to the USB ports, and the wattage on the DC plug actually dropped to 30 watts. so again, full sun / no clouds and only getting a fraction of the rated output.

50watts is the most I could get out of this "120watt" unit. Awful, just aweful... I have little foldable units that push more than this. I am very unhappy with this panel and am very sorry I bought it. $200 down the drain...

The build quality seemed good. It is bulky. The stands ok. It provided USB power on the USB-A ports and the 12 V voltage outlet, but I could not get near the advertised output. Less than half. That possibly could have been tweaked to more with better placement and light conditions. But the biggest problem was the USB-C port. Nothing, Nada. No output. I had to send it back, which I did not want to do.

Easy to set up and get running. With good sun, it charges my Anker Powerstation 800 II almost as fast as plugging it into the wall. As a note, for that charger the “Anderson” cable that came with it had the plugs oriented wrong for use with this battery. However they were easily split apart with a screwdriver and could be reoriented to fit perfectly.

I was able to get 55 watts of DC solar output on a Texas winter day (with UV4). However, the USB-C output does not work, whether I tried to use it while also using the DC or whether I tried to use it alone. The DC output was okay since my Powerstation only accepts up to 65 watts of DC input. But it would charge faster if the USB-C output also worked. If this panel was half the price I would keep it, but for the price I paid I expect more, so I’m returning.
