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.

Excellent support and replacement of… Excellent support and replacement of defect AB 1000's without any problems. Solved the issue, so now everything is working very fine. Thanks for this great Support and Sevice too.😉👌

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

Faulty Power bank and they didn't even respond to my email Received a Zendure powerbank as a present and it's not working right. Stops charging external devices after the power level drops below 40% and then turns off. When I subsequently recharge the power bank it always starts charging from that same circa 40% mark meaning that I'm not getting close to the battery capactiy which I should be. Emailed Zendure with the problem 10 days ago and with a video of the problem and they didn't even have the courtesy to reply. TLDR: Faulty power bank and terrible customer service - buy another brand (Anker for instance have great customer service usually)

Great product with excellent warranty Had an original Zendure wall charger which stopped working after about a year. Contacted their service which sent me a new knee at no cost. Also have a newer generation wall charger. Both work great! Charge super fastest multiple phones!
