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

Hi Zendure I bought 3000 euro worth of… Update At least they respond to reviews. I wrote the better buisness buro and the handels register. Within a day of writing i received word they would refund me. Five days later the refund was at my bank. So they are listenning. Would have simply been so much better if they had been listenning the four months before. But in the end I went with Bluetti...in the time it took to get my refund I have a new system, great service and lights...finally. I will give zendure another star for trying to solve it. But cmon guys. You know better. Original review Hi Zendure I bought 3000 euro worth of your product and STILL have not received it. It was supposed to be delivered in November!!!! I write, I call, and always I am told that you have no idea when I will get my order. This is truly unacceptable. I surely can wait a bit but our build is now waiting only for this product so we can HAVE LIGHTS!!!!!! please, I wish some customer support and my product. AND that you actually have customer support - your telephone lines are just recordings, your tickets are just autoresponders- I am hoping this will reach someone. I was excited and hopeful about this company and truly sad to see it might be a BIG SCAM. really hopeing not so please @ZENDURE - please fix this, send me my paid for product - respond to my inquiries, Fix your support so that it actually works instead of autoresponders and no people - Please prove me wrong!

Solarflow problems after adding new AB2000 After some starting issues our Solarflow with 2 AB1000 was working properly and we were happy to have them. So we decided to add another AB2000 to the system. Unfortunatly there was an unsolveable software bug as soon as we added the AB2000 to the system and made the update to the AB1000 akkus. After contacting the support via e-mail it took some time till we got an answer. Finally Mrs. Jessica Wen took over our case and we got the needed answers and help very quickly. The system will be replaced and we are looking forward that finally everything will work again as properly as it did before. Thanks to Mrs. Jessica Wen for her great support!

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.
