Faulty Power bank and they didn't even respond to my email Received a Zendure powerbank as a present and it's not working right. Stops charging external devices after the power level drops below 40% and then turns off. When I subsequently recharge the power bank it always starts charging from that same circa 40% mark meaning that I'm not getting close to the battery capactiy which I should be. Emailed Zendure with the problem 10 days ago and with a video of the problem and they didn't even have the courtesy to reply. TLDR: Faulty power bank and terrible customer service - buy another brand (Anker for instance have great customer service usually)

Solarflow problems after adding new AB2000 After some starting issues our Solarflow with 2 AB1000 was working properly and we were happy to have them. So we decided to add another AB2000 to the system. Unfortunatly there was an unsolveable software bug as soon as we added the AB2000 to the system and made the update to the AB1000 akkus. After contacting the support via e-mail it took some time till we got an answer. Finally Mrs. Jessica Wen took over our case and we got the needed answers and help very quickly. The system will be replaced and we are looking forward that finally everything will work again as properly as it did before. Thanks to Mrs. Jessica Wen for her great support!

ZENDURE V4600. Slick,functional,great value Customer service was responsive to shipping updates. Once arrived boxing was clever,safe and extraordinarily made for us and ease of removal. The v4600 and satellite battery are made well, designed well, and have been charging 2.33kw, and discharging into a heat pump daily. Really cutting down the use of the whole house hvac, while giving security of several to 9 kw in case of down grid. Self moving and tricked out lighting for kicks. Little loud, and no input pv cable so 4.8 out of 5 star, but if in market for a big solar battery, I'd look at zendure for sure.

Exceptional customer support. The display on my SBP2000 went blank when trying to use the unit recently, and I was having difficulty pairing it to my phone through the Zendure app. Selma from Customer Support walked me through the hard reset process and unpaired my SBP from an old account I apparently had before so I could set up anew. Her patience and persistence with me was exceptional. Many thanks.
