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.

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)

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.

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.

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!!
