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.

these devices are fine until you need… these devices are fine until you need them, they require constant management else they run into a firmware problem and them whatever was plugged into them like a refrigerator is no longer backed up, no warning nothing. unless you can afford to constantly monitor the device, you cannot rely on it to just "be dumb" until the firmware is updated. by time this happens its out of warranty. also currently cannot explain to anyone how it will not charge over the amp demand in ac wall mode. no one would take the time to understand that just plugging it into the 120v ac outlet isn't good enough for it to be a backup battery in ups mode. it still requires a 12vdc source to provide additional charge over the ac demand it may currently need. in short fine for someone who will charge it and use it as a massive cell phone booster battery, no someone who needs it to be an uninterrupted power supply

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.

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.

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.
