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.

No response since weeks, return impossible The support is not answering my request now since 1,5 months. I wanted to replace the PVHub-1200 with the PVHub-2000 since it has been released few days after i placed my order or send back the complete set. There is also no return shipping address published on zendure.de. So it's a deadlock situation with no return address and unresponsive support. I will try to return either the PVHub-1200 or the complete package to the original senders address and activate paypal buyer protection if no money has been transferred back. in addition it is stated that there is a 3,6% "transaction fee" (for paypal, 2,6% for credit cards) in case of returns which is against austrian law.

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.

No service at all! No service at all! Waited for five (yes 5) month to NOT receive my Solarflow setup. The device was promised several times and delayed even more, my doubts where not answered. In general a no service and happy I received a refund (CC company). I will buy similar hardware with another company as Zendure can NOT be trusted. All info can be proven with all my emails, tracking numbers and money receipts.
