Bests & Worsts Reviews from Amazon

First and foremost... The AC200Max is an outstanding unit with barely any competition. I did my research for almost a year reading about most units sold and available to me. My research looked into the 2Kwatt units available. After all the time spent, months worth, I decided that Bluetti had the best technology and record for my needs and investment. I received the unit and packing proved to be excellent. The unit had no harm and all components came in the box per description. I did purchase a single 200 watt Bluetti Solar Panel to test the Solar Charging ability; I'll get into that shortly. Simple enough, I pulled the unit from the box and turned it on. It had about 60% charge from factory. All powered up and lighted on per included manual. The manual is simple with good illustrations and numbers to reach for support and extra parts. This unit can be charged using: 1. Wall Charger 2. Car Charger 3. Solar Panels 4. Battery, Gas Generators, etc... I plugged the wall charger and proceeded to follow the manual to top it off the wall. This is where the labor pains started; NOTHING HAPPENED. No matter what I did, the unit did not charge using the wall charger. The wall charger worked good giving a 57.4watt reading at the tip (within specs range). I wrote to Bluetti through Amazon and directly to Support and within a day I had an answer. That was a relief since I was expecting a long and tedious wait. Support was quick to suggest testing Car Charger and Solar Charging to verify any further issues. To my surprise and due to my ignorance, I had only purchase a single P200 panel which was not enough to trickle the unit into solar charging....I was kindly suggested to purchase a second one which I promptly did. Support was quick to move heaven and earth to make it happen ASAP and I am very satisfied with their help. The car charger worked good, no issues. I was still out waiting for my panel purchase to arrive so I continued testing what the wall charger issue could be. It was not long before I found out that the AC200Max units had been having a reverse polarity issue at the 30Amp socket. I tested mine to check if mine had the issue and surely enough it did. I emailed Bluetti support on the matter and surely enough they did answer right away... I have to commend them on their prompt responses, they are quick and that was my experience. Support engaged with me back and forth emailing for weeks trying to figure out what the issue was. I am technically oriented so my idea of the problem took a different north from theirs but understanding their expertise, I kept shut and followed instructions which they did send. Support also went to the extreme to replace the wall charger and also sent parts to fix the reverse polarity issue of the 30amp socket. I am talking fast response and shipping. I was, still waiting on the panels to be delivered... More weeks into it, and many emails more, communications stopped. No more. I have been writing to Bluetti but have been placed on the ungrateful list (my opinion). Their support on the wall charger has stopped no matter to my efforts. It's a shame.... I gave up on them and though they were very courteous all the time. I have not changed my opinion on the product, it is solid and extremely high quality while competitive. If only they knew that being left out in the dust with no support, other than send the unit back for repair/replace at your expense, became the solution to the problem. I have to tell that I proceeded to take maters into my own hands. I followed a few emails where the unit is opened and which led me to safely and surely understand the innards of the unit. Once open, I found that my first suspicious was right where it was merely a cable at the wall charger port inside the unit. Easy to spot and easy to fix; plug was in and unit working. It took the wall charge about 2 hours to top of the remaining 40%. I estimate the time since I was out doing some errands. Today, I have my 3 solar panels, wall charger, cables, car charger... everything works as it should and the unit is safely stored. It saddens me that it was not the units fault. Inside an envelope I found a little piece of paper that certifies the unit as being inspected. It evens tells you which inspector was... Are you thinking what I am thinking...? So, finally, this is my story. Would I buy again... I did. Am I happy with support, NO... and YES... Quality - CHECK Price - CHECK Support - MIXED PERFORMANCE - CHECK I say go for it and keep your receipt...
