Review on ๐Ÿ”† ITEHIL 100W 18V Monocrystalline Solar Panel โ€“ Portable & Waterproof Charger with USB/DC Outputs for Outdoor Camping and Power Stations by James Mcphearson

Revainrating 5 out of 5

Good quality panels

Bought two of these on the recommendation of Goneagain's YouTube channel and another reviewer who used them to charge his Bluetti AC200. Very compact. Lightweight and appears to be very high quality materials. As with the other review, I need to figure out how to set it up consistently. Once I've done that, I'll make a change with an explanation. I really think this panel delivers as others have said it would be one of the best features. Basically I currently use a DC fridge but the plan is to pair it with fixed panels on the roof of a cargo trailer that is in the process of being converted. This should allow me to spend more time away from the mains or a noisy gas generator. Fast delivery. So far, so good. I ended up buying two PolyEnergy Solar to 8mm DC jack plugs with a 5.5 x 2.1mm DC converter cable. These were 8mm/5.5 or 5521 with a transducer on one end and an MC4 on the other end. This allowed me to connect the panels in series. Unfortunately, it also wilted me in the wrong direction to hook up my inputs for Bluetti. So I bought some extra 20ft MC4 cables and an MC4 connector toolkit with some connectors. This was all very good because it gave me the extension and allowed me to make the double sided connections I needed. The extension allows me to park the rig in the shade and have kit for future wiring. So the extra $60 was well spent. Finally done, I plugged everything in, checked polarity and got about 120 watts with some cloud cover just before the storm cloud rolled in and the day ended. It seems to me that in full sun I will get about 200 full watts. So there is still no good rating. Maybe I'll buy another one or two.

Pros
  • Very good value for money
Cons
  • Unbelievable price
