Persistence until the problem is solved I had ordered the AB2000 together with a SolarFlow system before Christmas with an announced delivery date of January 10. Everything was sent as announced, but to a wrong address, so that both packages were returned to sender. On the second delivery attempt, I again saw an incorrect delivery address, which I immediately reported to Zendure Support. In the end, the two parcels have been delivered to the correct address a few days later. The forwarding of a power socket also worked straight away. I was supervised by the same person at support throughout the whole process, so I didn't have to explain everything all over again. Thank you very much for your persistence.

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.

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.

Lea from support was fabulous Lea from support was great - I also faced issues with noone answering - until Lea took over. I got my request solved within 2 weeks (replacment of cable initially not sent - cable for connecting satelite and SVB). Many thanks to Lea for her great support and almost instant answers! @Zendure: make sure you have more than just Lea in your support team, things will pick up. However, make sure you value her - she know what customer support means!!

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.
