ZENDURE V4600. Slick,functional,great value Customer service was responsive to shipping updates. Once arrived boxing was clever,safe and extraordinarily made for us and ease of removal. The v4600 and satellite battery are made well, designed well, and have been charging 2.33kw, and discharging into a heat pump daily. Really cutting down the use of the whole house hvac, while giving security of several to 9 kw in case of down grid. Self moving and tricked out lighting for kicks. Little loud, and no input pv cable so 4.8 out of 5 star, but if in market for a big solar battery, I'd look at zendure for sure.

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.

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

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.

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
