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.

ZENDURE V4600. Slick,functional,great value Customer service was responsive to shipping updates. Once arrived boxing was clever,safe and extraordinarily made for us and ease of removal. The v4600 and satellite battery are made well, designed well, and have been charging 2.33kw, and discharging into a heat pump daily. Really cutting down the use of the whole house hvac, while giving security of several to 9 kw in case of down grid. Self moving and tricked out lighting for kicks. Little loud, and no input pv cable so 4.8 out of 5 star, but if in market for a big solar battery, I'd look at zendure for sure.

Slow support The original power bank had a defective output. While a replacement was shipped quickly it arrived completely defective. It will not charge. I have made multiple attempts to contact and they still refuse to respond. ** Updated - Support finally reached out and sent a third unit that works fine.

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.
