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.

Scam Returned my new sealed order.. never refunded I paid 172.64 USD .. I requested a return for a refund for my order 7798 for power bank ..as soon as I received the package as it’s under 30 days money back guarantee, after emailing them hundred times they finally answered me with a return address .. I send the item back to Canada address ..It was send by purolator under tracking number 334532883686.. they received the package on 31 January .. after that they never replied .. and no refund has been made!! Scam And by the way the item was new and sealed .. stay away from Zendure .. customer service is big ZERO

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)

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!!

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.
