I had a 5.8 watt reolink panel chewed by rodents, so I got this to replace it. You can see in the photos this is very slightly larger than the reolink, and cells don't cover the entire area. Efficiency is generally very similar on solar panels, and I wouldn't expect a cheap replacement to have higher efficiency than the more expensive reolink. Put all that together, and I'm skeptical of the 8 watt claimed output. Aside from that, I mostly like it. The sun-facing side of the panel feels like glass (instead of plastic as on the reolink). So that's a plus. The nut to tighten the mount is close to the bottom side of the mount (where you screw it to the wall). That's more accessible than the nut on the reolink, which is up close to the panel. When the panel is set at an angle, that can interfere with tightening the nut on the reolink mount. So that's another plus. But the mount is plastic. I move and remount these occasionally. I'm using the camera for wildlife monitoriing on a large property, so these are moved. I'm unsure how well the plastic mount will hold up tightening the scews every few months when I remount it. So I might end up re-using the metal mount from the reolink.

The Suner Power SP-20W-M PRO solar battery charger with MPPT charge controller is a great little 20W (20V, 1A) charger that works as specified. In bright sun it delivered a little over 1A when connected to my Prius AGM auxiliary battery. We don't drive much, so I plan to use this charger to top off the battery every month. When I disconnected the charger from my car battery, I could see that the open circuit voltage was about 21v as specified for a second until the unit shut down. I don't have the test equipment to test the MPPT function. The controller can be set for use with standard 12V batteries, 12V AGM or12V lithium-ion batteries. This includes lifepo4 batteries, but all lithium batteries must have a built-in battery management system). The charge controller has LED indicators for reverse connection and State of Charge, The unit came with nice long leads and two options for connecting to a battery. The 4 page User Manual was complete, although some of the wording was "broken" English and required a little interpretation on my part. It includes a basic testing procedure for those who might not know how to do it. I've only run this for a couple hours so I can't comment on reliability. The manual states the unit comes with an "extended 12 months warranty". Support is by email and they claim 12 hour response.

I have found XT60 connectors to be far superior to the older SAE style for RV, automotive, and other low voltage applications. XT60 makes a much better electrical contact than SAE — I've never had one fail or become intermittent. I also like the "look and feel" of XT60 such that you can easily determine the gender and polarity even in the dark. This item consists of a hermetically molded XT60 female connector at one end, and a set of male and female solar panel connectors at the other end of the cable. The current tugapower.net listing price of $10 (with coupon) represents a good value for this well made item.

Great portable battery for on the go or backup battery. Holding the power button for a few seconds to turn on each module. Charging is fairly quick when you first charge it. Tested the product on garage lighting LED's. Seems to hold well with the battery.
