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.

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.

I am at my wits end with this company I am at my wits end with this company. I have been waiting over six months (yep, six months) to get the unit returned as it doesn't work. Jamie J emails constantly to say your return label is being generated - nothing transpires. The unit is next to useless. My fridge and freezer have defrosted twice because the thing either switches itself off after firmware issues or runs out of charge with no warning. The battery capacity is useless. My Jackery has half the so-called capacity but lasts twice as long. In short, I'm happy to be patient when a new company has issues but this company treats customers like mugs and ignores issues.

Grace at Zendure was responsive and… Grace at Zendure was responsive and professional. I was disappointed that my £48 battery pack had completely stopped working after only 3 months. (I paid that much bc NYT Wirecutter rated the product so highly.) Grace/Zendure honoured the warranty and sent a replacement within a week of my being in touch about the problem. Graces communication was always clear and prompt. Hopefully this one will be top quality as hoped.
