In reading many of the reviews, there isn't a proper analysis of the performance of this solar panel. Most of the feedback is anecdotal. I have set up this solar charging panel to charge a backup battery that I intend to use for portable radio operations (POTA). The battery is a "Howeasy" 88 Wh lithium ion power station with a various outputs including 12 volts DC , 110V AC and USB charging outputs. The battery is charged at 15-24V with a nominal input of 15V/1.5A with a solar panel. The powerpack supports pass through charging. The solar panel is extremely well built and has a heavy duty/rugged quality feel. It folds into a manageable size package for backpacking. The charger is bundled in a heavy duty rip-stop material cover. It comes with a complete kit of plugs that will fit almost every need. The plugs are stored in a pocket designed into the cover. I configured the solar charger with the battery in full December afternoon sun. The charger came to life immediately. It was connected to the battery's charge input. The battery was partially discharged prior to charging. Initially, the charger operated at 22volts at 1.5A (33W) As the charge continued, the amount of current pulled by the battery diminished until the battery was fully charged. For this exercise, I did not attempt to charge a fully discharged battery. With the charger plugged in and opened to the sun, my radio drew 25 watts of power from the battery while the battery voltage stayed right at 12 volts. With the solar charger unplugged, the battery voltage under load eroded to between 10.7V and 11.4V which is a battery issue. Many of the reviews remark that the charger puts out less power than specified. What people need to understand is that the amount of power that the solar charger delivers is dependent on the load (the battery) The battery power draw is determined by the battery's Battery Management System (BMS) that controls the charge rate of the battery. While the charger is specified to provide up to 60 Watts, the battery may not draw this amount as was demonstrated here. A proper evaluation of the solar charger would employ a calibrated laboratory load which I did not have. Bottom line: This is an ideal charger for the power station that I have and I am pleased with my purchase. It is well built and well configured. I would recommend this product.

I got the 15-foot L14-30 to SS2-50R extension cord to use with my generator. I personally find SS2-50 connectors to be easier to work with than L14-30 due to the handle. I also think they're a bit safer than L14, because the ground pin in the center makes contact with the target inlet BEFORE any hot blade makes electrical contact. There's really nothing I can do about the socket that's on the GENERATOR, but I can absolutely choose my preferred outlet+plug type for its entry point on my house. The cord is ETL-certified. ETL doesn't have the public relations budget & consumer outreach of UL, but it's accepted by American insurance companies and most (if not all) building code jurisdictions in the US. Basically, UL developed the test standards, ETL applies them, and the end result for consumers is the same. The cord conveniently includes a carrying strap and adapter ring to facilitate more secure attachment to some inlets.
