Quick Summary: Big Battery, Small Package
The Bluetti AC50B Portable Power Station is a versatile and reliable power source designed to meet a variety of energy needs. It’s an entry-level power station that does a great job at keeping small devices running while keeping the costs very low. If you want a device to keep your phone charged while camping, it’s hard to find a better choice.
Key highlights include:
- 448Wh battery capacity with 3,000+ cycles at 80% capacity
- Multiple output options including USB and 700W AC outlet
- Compact and lightweight design at just 14.8lbs (6.7kg)
Whether you’re camping in the wilderness or have a short power outage at home, the AC50B can keep many devices running and charged at the same time. This includes USB-A and USB-C ports, plus the regular 120V outlet for low-powered devices.
This battery surpasses most in this class, making it a standout in the Bluetti lineup and compared to rivals. At 448Wh, it can fully recharge a cell phone about 30 times or a laptop about 8 times. It could keep an LED light running for over 40 hours. It’s perfect for a minifridge or as a backup energy source for a medical device like a CPAP, keeping them going for 5 hours or more.
Plus, the battery is made from industry-leading LiFePO4 chemistry and rated to have 3,000+ cycles at more than 80% capacity. It will last around 10 years of daily use without putting up a fight.
These features make the Bluetti AC50B Power Station an excellent choice for those interested in a small amount of portable power.
It’s available as the Bluetti AC50B power station alone or as a solar generator package with one 120W solar panel.

Outlets Galore
There are 6 different outlets to connect your devices to the Bluetti AC50B. No matter what device you want to charge, there will be an outlet to match.
The USB ports are some of the most common you’ll need. The AC50B has two ultra-fast 65W USB-C ports and one USB-A port. You can hook up a phone and tablet, plus still have room for a camera battery. And there’s another DC outlet, the common car cigarette lighter port. That can be used for portable fridges and any accessory you already use in your car’s 12V outlet.
And for those small devices that need the 120V outlet, the 700W AC inverter is there to save the day. With a surge power of 1,000W, it’s surprisingly robust for this little power station.
The two AC outlets are perfect for small devices like drone batteries or a CPAP and other small medical devices. But it is a smaller inverter so it can’t handle an air conditioner or a full size fridge. That is what this price level gets you and how it stays super portable.
It also functions as a uninterruptible power supply, with a less than 20ms switchover time. You can keep your critical devices running nonstop, using a wall outlet most of the time, then automatically switching over to battery power when the grid cuts out. That’s the benefit of this 20ms UPS function, something other small Bluetti power stations don’t have.
The AC inverter has a peak output of 1,000W that can handle small startup surges, but for the most part, you’ll want to stay to lightweight AC devices that pull no more than 700W, such as a:
- Laptop
- Minifridge
- TV
- Fan
- Portable speaker
Simply put, there’s no disappointment in the outlets available on the Bluetti AC50B.
448Wh Battery: Ready for Action
The Bluetti AC50B offers the perfect blend of portability, durability, and capacity. It’s the ultimate solution for anyone who values dependable power on the go. You can gear up, stay connected, and let the AC50B power your next adventure or keep your home running smoothly.
This compact portable power station is equipped with a robust 448Wh battery, featuring LiFePO4 battery chemistry. It guarantees over 3,000 cycles at 80% capacity. While others might disappoint you in the near future, this little beast will keep running strong for upwards of 10 years.
As an ideal choice for camping trips and short-term home backup, the impressive battery capacity ensures you can keep essential devices running smoothly. It’s not the biggest power station around, but it’s not trying to be. Instead, it provides peace of mind whether you’re out in the wilderness or dealing with a power outage at home. And it can handle your needs tremendously well, such as:
- Smartphone: 30 full recharges
- Laptop: 8 full recharges
- LED Light: 40+ hours
- Mini Fridge: 6-8 hours
- CPAP Machine: 5+ hours
If that’s not enough, you can use the Bluetti B80 Expansion Battery to add another 806Wh of capacity. This opens up an entire world of possibilities where the limits stretch as far as you want. Simply connect the extra battery into the XT-60 input to instantly add more than double the battery size. It won’t ever reach the size of the best solar generators for home backup, but it can bring a sizable battery anywhere.
For outdoor enthusiasts, the AC50B is a game-changer. Imagine setting up camp and knowing that your mini-fridge will stay cold, your CPAP machine will keep you breathing easy, and your LED lights will illuminate your campsite well into the night.
Even in emergencies, having a dependable backup like the AC50B can make a significant difference in comfort and safety. It can keep your phones going, keep your internet modem and router running, and let you use lights and tablets all night long.
No more reaching for flashlights with dead batteries or being worried that your phone will die any minute. Stay connected and charged through extended outages and emergencies.
With the Bluetti AC50B, you don’t need the largest or most powerful unit to meet your energy needs. Its perfect balance of size, capacity, and durability makes it an excellent fit for anyone seeking a versatile and reliable portable power solution.

Comparing Bluetti AC50B vs. Other Power Stations
When comparing the Bluetti AC50B to other portable power stations, it stands out as the newest model with a robust 5-year warranty and long-lasting 10-year battery life. But there are many other small portable power stations that are similar, even from the extensive list of all Bluetti power stations.
For instance, the Bluetti PS72 offers a higher capacity of 716Wh and 12 versatile outlets, but it only supports up to 2,500 battery cycles and has a slower AC charging rate of just 200W.
The Bluetti EB55, with a 537Wh capacity and a 700W AC inverter, also falls short with 2,500 cycles, despite having more outputs and faster dual charging options.
Other notable competitors include:
- EcoFlow River 2 Pro: 768Wh battery, 800W inverter, but with fewer cycle ratings and shorter warranty.
- EcoFlow River 2 Max: 512Wh battery, 500W inverter, good for mid-range power needs.
- Anker 522: 299Wh battery, 300W inverter, ideal for smaller devices but limited capacity.
- BougeRV Flash 300: 286Wh battery, 600W inverter, compact and powerful but lower capacity and cycle life.
