BLUETTI AC2A Portable Power Station, 204Wh Solar Generator LiFePO4 Battery Backup w/ 2 300W (600W Power Lifting) AC Outlets, Recharge from 0-80% in 45 Min, for Camping (Solar Panel Optional)

I bought this to replace the one that someone stole. This is the company I have relied upon for a decade with high quality chargers and power centers. I had a laptop charger from them under the Max Oak line that lasted for years of daily use. When I needed a power center, I looked at their products first because of their reliability. The power center appears to use smart charging principles to safely charge devices. Since I full-time RV, I put my AC2A through daily use, and appreciate the fast charging capability in around an hour. I charge it both from solar and an AC outlet, depending upon the time of year. I like how I can charge multiple devices at once, including AC devices as well as 12 volt and USB C and A devices. It will do pass-through charging as well. The solar and AC input cables are included. It has a robust design, is easy to use, and represents a great value. I highly recommend this brand.

I’m very impressed with the BLUETTI AC2A. For its size, it delivers outstanding performance. It charges extremely fast, the LiFePO4 battery feels very reliable, and the multiple output ports make it perfect for my daily use. I use it to power my phone, laptop, small tools, and even LED lights, and it works flawlessly every time. It’s lightweight, easy to carry, and the build quality is great. If you need a compact and dependable power station for travel, emergencies, or outdoor use, this one is definitely worth it!

( The following paragraph is a bit of an update May 2024/ I am way past my first day and this device continues to serve me on a daily basis. I had the equivalent battery from a respected brand and never felt compelled to use it as much as this one. I have since been compelled to buy the larger AC180. Combined together, the two batteries will keep my full size desktop computer with two monitors and my internet router, with a light and a fan running for a whole day. Today infact, we had several waves of storms come through Houston. And while several of my coworkers dropped off one by one as internet and electricity flickered I remained constant. And indeed my home did lose power briefly, and the lights were shutting on and off. The UPS mode on these batteries have worked in real time.) It has been only one day and this has saved me. I work from home and my power went out. This device had enough power to keep my desktop computer running for four hours. I could monitor my power from my ipad as I was working. I just happened to purchase the car/ xt60 adapter. This allowed me to use two Anker 521 solar banks as a bolster to keep me running a full work day. I love my Anker 521 s and their amber light, and their slightly higher capacity. However I lost power once for 48 hours. With a generator it still took way too long to top off these banks. The bluettie will turbo charge itself with that same generator in a really short amount of time. Eventually my power came back on. Instead of unplugging my computer I just plugged my bluetti back into the wall. The bluetti charged itself and once full it used the wall power for the computer. It really does pass the power through. Where my Ankers seemed to sip on the battery power potentially degrading the battery over time. This really could be used as a UPS, and i will plug into my bluetti when the next storm comes. For some reason my Ankers did cause my computer to shut down as if a surge had tripped them at least three times in eight hours. The Bluetti with the same 300 watt, but lower watt hour, did not have this problem. It was smooth sailing. My desktop computer was only using at max 30/35 watts. This Ac2A reminds me of the Ecoflow that I always wanted, the River Mini. However the mini did not have LIFEPO BATTERIES. They were only good for 500 cycles before degrading. This Bluetti is potentially good for 3k cycles. The Ankers have a conspicuous lunch box appearance. The small size of the bluettie and hidden handle would make me feel less conscpicuous if I needed to emergency charge at a coffee shop for instance. There was a Hurricane I went through where half the city grid was down. With a device like this I could have run to a family members house and zip zoomed a charge really fast. Heck just driving and charging would have almost had me to full. In emergencies speed charging is king! Here is another kick. I have power banks that output 65 to 100 watts. Potentially I could use a usbc/ xt60 adapter to support my bluetti with those banks. I will have to test that later. I know my ankers will siphon power from those banks with a usbc to usbc connection. Tax Return season is here and I am allready eyeballing the bluetti AC180. With this speed charge technology, if paired with a propane generator, I could survive a hurricane power outage in style. And keep the emergency devices topped off. Living through the Texas freeze gave me an interest in these devices.

We have been having a lot of power outages in San Francisco recently so I decided to buy this AC2A portale power bank to recharge my many rechargeable motion and lantern lights. I received the item VERY quickly, sooner than expected which was awesome! =0) Product is really well made, solid weight with excellent aesthetic and functional design re: rear handle and rubber feet on the bottom. It is very sturdy and balanced! It's best to leave this item on a flat, solid surface/the ground for San Francisco since we have also been having a lot of earthquakes the past 3 months in California! The LCD display resolution is excellent and the front buttons are easy to read and understand. The device arrived about 57% charged, but I used the included heavy duty guaged black power cable to charge it fully to 100% before testing with my rechargeable devices. The A/C charging for my Dell laptop worked perfectly once I turned the device power ON and the AC power to ON, laptop charging was very fast within 45 - 60 minutes or so, however, it seemed to draw the battery down to about 50% which I am worried about. I might need to upgrade to a bigger, better Bluetti model. I'm still testing. The ISSUE that I had and why I marked this down 1 star is because when you plug in to USB-A or USB-C ports, it wouldn't charge any of my rechargeable smaller lights and iphone. I looked at the Instruction Manual and didn't see a word about it needing to turn on anything else. I asked ChatGPT and the response was that the device was "defective". Since I am a Technician, I decided to play around with it and turn on the DC button to ON! Turns out that in order to use the USB ports for charging, you must turn the DC button to the ON position! How or why Bluetti could ever miss out on putting this in the Instruction Manual or a quick sticker on this device is beyond me. If Bluetti ever needs technical reviewers, please contact me. I LOVE testing technology and providing reviews! =0) I've only been testing this device for 1.5 days now, I ordered another Portable Power Bank - Jackery 240D - which will arrive on Tuesday or so. I will compare these and keep both of them if they work well because I need to give one to a Family member too. The jury is still out, but this Bluetti construction, design is very well made. Finally an awesome, high quality item in modern day times. Thank You Bluetti, I will continue testing this device to see if it is powerful enough for my needs. The other BAD thing I want to mention is that I wanted to order the Bluetti OEM DC charging cable so I could charge it from my car, but the Bluetti OEM charging cable is NOT available on Amazon, nor from the Bluetti website that I could see as of last night! Bluetti tells us that we need to purchase the model, but only sells the Aviation charging cable! Please update your Bluetti website with the DC car charging cable and also supply Amazon with it so we can buy it ASAP. With extreme power outages, I would need to recharge this device via my car DC port or purchase a Solar Panel, but sunshine in San Francisco is not consistent ESP during this cloudy, rainy season.

So far this little unit is working 24/7 keeping my PC running as a battery backup without any complaints. I didn't buy this unit as the primary backup for my PC but my large Bluetti died and had to send it in for repairs. Customer Service support is a bit disappointing over the phone so most of the time my correspondence is done by email. They need to improve CS still. I might to an update on this unit in the future especially if there's any failures. But I think this is a solid unit, definitely quite even under full load. Beautiful screen, completely App control, charges in an hour easily if not quicker. I do wish it had a little bit bigger battery capacity but no biggie for me. I haven't had a chance to try the solar panels on it yet, I'll probably do that when my other unit is returned from Bluetti. Love all the app functions, excellent 👍 options. Bluetooth only no WiFi, wish it had an extra type-c outlet. Updates coming later on. Update 10/10/25: Complete failure! Suddenly! Power outage in the middle of the night is not a good reason but it happened. Battery alarm flashing on the screen, stopped charging at 45%, AC, Power and DC buttons flashing. I unplugged it from the grid and it completely turned off. Plugged it back in and screen came on for 5 seconds and turned back off. After that, that's all it would do. Emailed CS , filled them in on what happen, sent in photos and all necessary information they requested for return. Took about a week to find out if it was fixable and they said it was bad unit and they will be replacing it with a refurbished unit. Ok accepted. CS followed up to make sure unit was working fine and to make sure to test it. That unit a well used replacement unit lasted until last week. The screen went wacky and showing all kinds of letters and numbers even though power output was still functioning. Sent another email to CS, told them everything, sent photos and next day they sent FedEx return label for me to return for new replacement. Hopefully the replacement isn't another well used refurbished unit.

I purchased the Bluetti AC2A and have been using it for just over two weeks. I plan to use this for off grid and as a backup device. I needed a minimalist configuration that was portable, lightweight and transportable to an off grid seasonal property. My initial results of this unit are better than expected. The power station is made for outdoor use, and has a wealth of capabilities despite its small size. It's ideal for camping and hiking trips, or any other prolonged outdoor activities. Weighing just under 8 pounds, the AC2A is very lightweight, making it easy to transport and store in your bag. The LiFePo battery capacity is 204 wh and it has 300w pure sine inverter power The unit was well packaged and comes with standard accessories such as an AC charging cable, MC4 solar charging cable, grounding screw, and product documentation. You can add optional accessories including a car charging cable or a B80 Aviation Plug to XT60 cable. The B80 cable would be used if you purchase a B80 expansion battery to connect to the AC2A. Here are some tests as I evaluated the unit: Unit Charging I solar charged the unit using 2 100w panels. These need to be wired in parallel due to the 12-28VDC limit with the AC2A. You can maximize the solar power to 200w. I was getting 135-140W with this configuration. Solar input can fluctuate based on the sunlight, panel positioning, and time of year. I charged the unit under AC mode and used the available modes. This included standard, silent, and turbo modes. I drained the unit and did some recharging using the available modes. In Standard mode it recharged in 1-hour 47 min. In Turbo mode, it charged in 1-hour 7min. In silent mode it recharged in just over 4 hours. I did some advanced turbo mode tests combining solar and AC and realized 276 watts. The XT60 solar port does allow for 12V battery connection with the proper battery cable. With standard mode the charging mode combination decreases to roughly 160 watts. Given I would use this unit off grid, I tested the AC mode with my 1000w gas inverter generator. I was able to fully recharge the unit under standard mode in under 2 hours. You need to ensure the gas generator has a pure sine inverter and THD (total harmonic distortion) is under 5%. Unit Loads I tested the ability to run 110/120V AC appliances up to 300W on the unit. I’ve been able to run a small fan, TV, humidifier, lighting and home office computer system. I tested DC power charging my phone, IPAD, and flashlight. I tested both the USB-A (2) and USB-C ports. The power consumption of my off grid is less than 200W and I can leverage this as supplemental power provided, I feed it with solar, generator, or battery bank power. To conserve power, I used the ECO mode on both the AC and DC mode. The ECO mode testing included activation from the unit display console, phone app, and setting based on a period of time. All scenarios worked successfully. I experimented with power lifting mode with an induction cooktop. The setting cannot power a 600w induction cooktop. I found the ac charging cable to be too stiff to hold connection in the charging port. I used a EB3A cable for charging. Other Testing Scenarios I examined the general display features and how to turn on/off DC and AC. The LCD display is easy to read. Timeout for the LCD is configurable. I found the smaller icons for state, performance, and fault to be on the small side. It required some cross reference to the manual for information. I tested mode setting on the display which allows you to toggle AC+DC buttons to set features like Frequency, ECO mode, Charging Mode, and Power Lifting. This is a great feature as you can program the unit without use of the phone application. I reviewed the phone application and found it easy to navigate and change settings. It does have limits as its Bluetooth based and you must be in range of the AC2A unit. One important test conducted was to use the unit with my CPAP device. I have a Resmed Air11 and wanted to test this with a DC power adapter. I configured the DC power adapter with the AC2A. On the AC2A side, you have to account with turning ECO mode off. As a contingency, I used an extra 40ah battery to recharge the AC2A in silent mode. I left the CPAP settings on for humidifier and heated tube. The DC draw was averaged around 35 watts. With this setup, I was able to get over 5 hours of CPAP usage. I plan to continue testing settings with the CPAP humidifier and tube settings off to lower battery consumption. It's possible that adjusting CPAP settings may provide dedicated AC2A capacity without an external battery bank. What I like so far I like the compact design including the handle, user friendly display, size, and weight. I like the ability for mode selection setting off the display. It avoids reliance on the phone app to change settings on the unit. I like the fast-charging features including charging modes, solar, DC, and AC charging. I like the fact that the unit has a 5-year warranty. This is very unique for the portable power station marketplace. What could be improved? The AC charging cable shipped with the unit was rigid and difficult to maintain a tight connection. I used my EB3A cable which is a smaller gauge and a better fit. The messages on the console are small. It would be nice to have quick reference cards within the app especially for errors or warning. Currently you have to navigate to the online or paper manual as a reference point. The Power Lifting feature is a less essential capability on the 300w inverter. I would have preferred a slightly larger inverter or more battery capacity. It would be helpful to add features in the phone app that are tailored to the devices owned by the customer. A quick reference main icon pertaining to the AC2A or other owned Bluetti device would be of value. Allowing the customer to tailor icons on the app would be a welcomed feature. There’s an abundance of Bluetti marketing icons the customer may wish to hide. More optional XT60 accessories would be a useful addition. For example, adapter plugs that fit a XT60 to DC7909 adapter or a 4 in 1 MC4 connector cable would benefit Bluetti customers with different models. Overall, this unit is a keeper. It’s extremely powerful and full featured. The footprint is compact and allows for easy transport.

Love this little power station. Its small and convenient. Works great to keep my stuff charged. I purchased to use when power goes out to keep my fishtank warm and the filter running.

TLDR: This unit didn't work out for me because charging it from a pure sine wave inverter makes it develop an unsolvable BMS fault error that requires replacing the unit. 4 stars for the slow but effective customer service. I bought this because I was looking for a small power station to keep in my truck. I had an AC and a DC-cigarette plug installed in the bed, with inlets for both in the cab that I wanted to hook this up to. I also have an inverter in the cab that draws power from the starter battery that I can use to charge the power station. This essentially allows me to run power to the bed of my truck so I can run box fans and keep my 12V fridge cold without draining my starter battery. I chose the Bluetti after quite a bit of research because it was compact, had both AC outlets and a cigarette DC port, and was reasonably priced (only a little over $150). I also liked that it charged with a plain Jane AC cable that could be swapped out if needed. I also read that the AC ports actually put out 120 volts, not the weaker 110 to 115 volts that my older power stations do. When I got it, I was pleased to be able to confirm the 120-volt output. This makes a big difference when you're running a fan, because more volts means it spins faster. I was very happy with the Bluetti for several months. It stayed put on the jump seat in the back of my truck cab, and it was easy to charge with the inverter whenever I was driving. It easily ran the fans and fridge I mentioned in the first paragraph. Unfortunately, it developed a "BMS fault" error a few months after I got it, and after quite a bit of troubleshooting I could not fix it. I got in touch with Bluetti customer service, which turned out to be an exercise in frustration. After several days of waiting for a response from the Bluetti CS email, I reached out again to Bluetti through Amazon. About a day later, I had a response from "Anson," who informed me that I would have to send the unit back for a replacement. This was fine, although I could never expect more than one reply from Bluetti a day, and it took several days to get the shipping worked out. Once I did, they accepted the return and sent me a replacement. Unfortunately, this unit developed the same issue only a few days after I received it. I can only assume that the Bluetti does not like to be charged through an inverter (even though I have a well-built pure sine wave inverter, whose power output should be indistinguishable from utility power to the Bluetti). I contacted Anson again, who gave me the option to get another replacement or to provide a refund. I took the refund and, after another few days of back-and-forth, sent it back and bought an Anker Solix C200X. This power station has been rock solid so far, just like my other Anker Solix units. This would be a great power station depending on your use case. I would recommend this unit if you'll be charging it exclusively from a wall outlet connected to utility power. If you plan to charge it with an inverter or some other off-grid means, I would recommend steering clear.
