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.

Great product with excellent warranty Had an original Zendure wall charger which stopped working after about a year. Contacted their service which sent me a new knee at no cost. Also have a newer generation wall charger. Both work great! Charge super fastest multiple phones!

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.

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.

It is a scam It is a scam. Products are either not working or not working as advertised. Constant problems. Support not answering for months.
