I recently purchased this product and I'm incredibly impressed with its performance (so much that I bought a second one). It was a lifesaver during recent power outages in Southern California, keeping my full-sized fridge and router/modem running without any issues. It even handled the surge of power required for the compressor to start up and run smoothly. I hooked it up to power my gas furnace when it got cold, and it had no problem running the ~750W blower. Another great feature is the very fast charging capability. However, there's a point to note here. Customer service informed me that some units, like mine, might require calibration after leaving the factory. The calibration process is not too hard: 1) Fully charge the unit. It might seem stuck at 99% for a while, but that's okay. This initial charging helps the Battery Management System (BMS) understand what "full charge" truly means for your specific unit. 2) Once fully charged, use the generator with a constant power draw until it completely shuts down. Don't worry, even at "0%" the battery still has about 10% charge remaining, so there's no risk of damaging it through full depletion. 3) Following this calibration process (full charge, then full drain), my unit now charges much faster (around 1kW when plugged into the wall) and the battery level indicator reads accurately. Overall, I'm very happy with this product. It's a reliable and powerful backup power solution that provided peace of mind during a power outage. The calibration process was a breeze, and customer service was helpful in explaining it. The associated Bluetti app is great, although I wish they would provide graphical data of power consumption, etc. I highly recommend this product!

Came in handy for any kind of camping, had no problem running fans all night in the tent keeping phone charged I used with my little compressor cooler to have a little fridge, also for beach days using this power bank in combination with the compressor cooler to pull out frozen popsicles and cold drinks, keeping everyone’s phone charged to keep the music going, it’s awesome. Works good on road trips - plugged right into the car no problem. I did a car camping trip across 7 states and this fits perfectly into the car and lasted for my needs, I got a solar panel to charge it that works awesome too. Even worked amazing during the last hurricane we had, I took it to my grandma so she could keep her phone charged to contact us but also to pass the time playing FarmVille lol, run a fan all night for almost a week straight till she got the power back on in her area. If bluetti ever decides to send free ones out I’ll take one lol, I have this one and the Eb3a both are great no problems going strong, I’m currently trying to saving up for a bigger one. These are definitely quality and come in so many uses.

Works as advertised! This unit rocks! The weight is bearable for the power. The handles are very nice. The readout is Bright and very Usable. I like the multi segmented circular bar graph, and the large digital read out. You must understand this: it's not 100% full until the input wattage goes to zero. At 1% left and 0.1 hours remaining, it's not done yet. I put a 150-Watt Lamp load on it from a full charge. It stated 6.5 hours at 100%. The calculations as described in manual yield 5.3 hours, however this was a lower estimate as it assumed 85% efficiency. Hours = (Wh * DOD * Eff)/(output Load + 15 watts), where DOD (Depth Of Discharge) is assumed 90%. At 4:47 Hours it was at 1% and 0.1 Hours remaining. However, the lamp continued up to 5:47 Hours, and died sometime after that. I repeated these 2 more times and got the same results every time. Understanding the readout estimates gives me confidence the unit is operating as advertised.

Works great for running fridge, microwave, tv during power outage. WH capacity is enough to run a big fridge for couple hours, and peak W enough to run a microwave oven. Weight is low enough that one person can lug it around (carefully). Charges fast on AC input. Phone app is nice. Sometimes wished it had 5521 DC outputs like other models.

I’ve had the machine for two weeks and have tested all of the features. It is everything that Bluetti claims it to be. It looks and feels like a quality device and it’s not too heavy (~16kg/35.27lbs) to take car camping. The UPS function actually works, even on devices with an electronic power button (such as a desktop PC) and that is unlike the emergency power source (EPS) system on a competitive model from another popular brand. I do wish the built in MPPT controller could handle more input current from solar. It is difficult to get close to the maximum 500W input from solar because of the input current limitation of 10A. 15A (like it can handle on AC) would be ideal on a machine in this class; however, a more robust MPPT controller and heavier gauge wiring would be required and that would increase the cost slightly. My only other wish for the AC180 would be rubber port caps for all ports, including the USB ports. If you charge the internal batteries outdoors with solar, dust and debris can collect in the ports. I purchased some vanilla port covers to take care of that, but they are not attached to the device so I may lose a few. The cooling fan does kick in when it is charging or discharging at a high rate but the sound is not as high pitched as it is on competing models. It isn’t quiet, but it isn’t horrible either. I downloaded the phone App to update the firmware. I don’t normally use phone Apps, but it was necessary in this case because you cannot update it with a jump drive or a PC. It works. I do wish you could set the display screen time out in the App. 30 seconds is okay, but when you are trying to optimize the position of your solar panels to maximize the input watts it would be nice to have the choice, rather than pushing the power button to turn the timed out display back on. Over all, an excellent machine and a good value if you can purchase it on sale for ~$1000. It will run a fridge over night in an emergency and has a large enough inverter (pure sine wave) to run almost anything for a short duration.

Used this a few times and I am really satisfied with it. The 200W solar panel does a great job in direct sunlight not taking long to charge (from 50% to 100%). Great piece of kit that I recommend to anyone. My brother saw it in action and now he wants one. I used power tools off it, accidentally left it on and still kept its charge. When on sale great value for your money. Not sure how it will handle the elements but seems durable for indoor use and outside not in the rain/snow etc

The first charge up seemed too quick but it's been functioning perfectly since. The solar charging did the same thing at first, only getting 15watts but the second test got about 160watts from my 200watt solar panel, which was expected. This battery ran my BougeRV cooler for over 40 hours while it was empty! Seems to use about 3% battery per hour when running at 35watts for the cooler/fridge. Very happy with this unit, and with customer service response!

Used it while building our new house. We powered our 160 square foot bunkie with it using the solar panels and when we had no sun we charged it with a generator. The one gotcha we had to deal with is that we had to purchase a new inverter generator as that is the only type of generator that is compatible with this unit.
