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

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.

I am at my wits end with this company I am at my wits end with this company. I have been waiting over six months (yep, six months) to get the unit returned as it doesn't work. Jamie J emails constantly to say your return label is being generated - nothing transpires. The unit is next to useless. My fridge and freezer have defrosted twice because the thing either switches itself off after firmware issues or runs out of charge with no warning. The battery capacity is useless. My Jackery has half the so-called capacity but lasts twice as long. In short, I'm happy to be patient when a new company has issues but this company treats customers like mugs and ignores issues.

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!!

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.
