XTAR sp100 100w Portable Solar Panel Solar Power, Foldable Solar Panel Single Panel Solar Power Panel for Power Station Solar Generator RV Solar Camping not Included Independent EU4S Charger

As a previous reviewer wrote it worked well until it didn't. It now does not charge any of my three power stations (jackery 500, ecoflow river max or anker solix c1000). The panel has been used maybe a dozen times over the last 2 years. After trying it recently in full sun, it failed to charge at all. I then did a internet search and found this company forgot to install a blocking or bypass diode which results in the panel "burning out" if it happens to become shaded. This is totally ridiculous for a portable panel that is used in forest locations which can become partially shaded. Supposedly xtar has installed a diode in units made after Oct 2022. I bought my panel in June 2022 & it is just beyond the warranty. I would not trust this company to have installed the right diodes after they forgot to install them in the first place. Very disappointed to say the least
