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)

Excellent support and replacement of… Excellent support and replacement of defect AB 1000's without any problems. Solved the issue, so now everything is working very fine. Thanks for this great Support and Sevice too.😉👌

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.

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.

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.
