Super rank replacement I bought a zendure supertank power bank via amazon in Nov 22. I began experiencing issues in Jun 23 and contacted their customer service department directly to enquire if my power bank was still under warranty. Grace Huang took my query and resolved within a week. I received a brand new replacement power bank within two weeks. At this point I would like to say that zendure brand of power bank are extremely durable and reliable. My family have three in total with two being almost 4 years old with no problems. Thanks Grace for your help, much appreciated, Neville.

Happy but careful. I'm thankful and pleased that I have received my SBV 4600 + battery about a week ago. I haven't installed it or used it yet, because l'm a little concerned about the firmware updates (and others having problems on which versions). I asked for and quickly received my MCA series cable (female) plugs, but they don't match the XT90 (also female) plugs to my 3 - 1000 watt solar panels (bought separately). So I can't use Solar for now.

Cool stuff It was all a great experience with the products. Everything is working as. Sometimes the customer service could be a little bit faster. But in the end all problems could be solved.

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!

No response since weeks, return impossible The support is not answering my request now since 1,5 months. I wanted to replace the PVHub-1200 with the PVHub-2000 since it has been released few days after i placed my order or send back the complete set. There is also no return shipping address published on zendure.de. So it's a deadlock situation with no return address and unresponsive support. I will try to return either the PVHub-1200 or the complete package to the original senders address and activate paypal buyer protection if no money has been transferred back. in addition it is stated that there is a 3,6% "transaction fee" (for paypal, 2,6% for credit cards) in case of returns which is against austrian law.
