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

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!

Super rank replacement I bought a zendure supertank power bank via amazon in Nov 22. I began experiencing issues in Jun 23 and contacted their customer service department directly to enquire if my power bank was still under warranty. Grace Huang took my query and resolved within a week. I received a brand new replacement power bank within two weeks. At this point I would like to say that zendure brand of power bank are extremely durable and reliable. My family have three in total with two being almost 4 years old with no problems. Thanks Grace for your help, much appreciated, Neville.

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.
