No service at all! No service at all! Waited for five (yes 5) month to NOT receive my Solarflow setup. The device was promised several times and delayed even more, my doubts where not answered. In general a no service and happy I received a refund (CC company). I will buy similar hardware with another company as Zendure can NOT be trusted. All info can be proven with all my emails, tracking numbers and money receipts.

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.😉👌

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.

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.
