Bluetti is a leading supplier of portable solar batteries. Compared to its competitors like EcoFlow and Jackery, Bluetti leads the global market with a wide range of affordable battery packs in all sizes and segments, from small and mini models to heavy-duty home battery packs. Here, I would like to have a detailed look at all of the brand’s ultra-compact and small solar power stations.
The brand offers around five small power stations: the EB55, the EB70S, the EB3A, the AC2A, and the AC60. The first four are regular power stations with LiFePO4 batteries, with the AC2A being the most recent one with a small battery of 204 Wh, while the AC60 is the brand’s smallest modular power station that comes with an extra battery called the B80.
The EB55 and EB70S come with the same 700-watt inverters, and they have almost the same design, except for the size and the battery capacity. The former has a 537 Wh battery, and the latter has a 716 Wh unit.
In the meantime, the EB3A has been the brand’s entry-level battery with a 268 Wh LFP battery and a 600-watt inverter until the AC2A was launched in late 2023.
|Update in November 2023: Bluetti launched the AC2A, the smallest of its small solar power stations, with a small battery of 204 Wh and an inverter of 300 watts.
Update May 2023: The Bluetti AC60 has been launched. This is the brand’s smallest modular power station with an LFP battery pack. The modular battery is the B80, with which the 403 Wh battery can be expanded up to 2015 Wh.
Update June 2022: Bluetti has launched the smallest of its LFP power stations, called Bluetti EB3A. Have a look at our detailed take on the handy and compact LFP power station here.

Bluetti Small and Compact Power Stations
The compact and small solar power station market has always been a hot-selling segment. With multiple models, including a modular one, Bluetti certainly turns out to be one of the most prominent brands for outdoor enthusiasts, campers, and preppers to rely on.
Compared to EcoFlow and Jackery, two of Bluetti’s key competitors, the brand has a great edge in the niche of small and compact solar power stations. The brand has designed all its models with the best technologies and batteries to make sure you get emergency backup on your camping trips and travels.
Bluetti launched the EB55 and the EB70S in a short interval, along with its famous mid-capacity and modular power stations, two years ago.
The new EB3A was launched in 2022 as the smallest portable battery with an LFP architecture. In the meantime, the modular AC60 was launched in 2023 as the world’s smallest modular power station, which still seems to be a proven claim by the brand.
By the way, AC50S was one of the small power stations from the brand with a lithium battery.
The brand designed the 500 Wh battery with a 300-watt inverter in response to Jackery’s then-best-selling Explorer 500 and Goal Zero Yeti 500. This product was later discontinued with the arrival of the new LFP battery packs in the segment.
Bluetti EB55 Solar Power Station
This can be one of the coolest compact power stations, with a reliable and ultra-stable LiFePO4 battery pack. Combined with an integrated Battery Management System (BMS), you get an awesome product of this kind.
The EB55 can offer a charging cycle of over 2500 times before it reaches 80% capacity. Of course, the 534 Wh battery pack is quite enough to power up most of your essential outdoor gear and gadgets.
The AC pure sine wave inverter is a 700-watt unit, and it can surge at 1400 watts. You’ve got it with four 110V AC outlets to power up necessary appliances like laptops, drones, projectors, RVs, and more.
It highlights a combination of 200 watts of AC and 200 watts of solar input for quick charging. So, you can achieve a charging speed of up to 400 watts by connecting it to the solar array and AC socket at the same time.
Further, if you can afford it, you can buy a second AC adapter to increase its AC charging speed to 400 watts.
By the way, the device can power up 13 devices at the same time, including the four AC appliances. The other charging points include a 100W USB-C port, four 5V/3A standard USB ports, and a 15W wireless charging pad.
The DC outlets include a 12V/10A DC carport and a pair of 12V/10A DC outlets for small AC devices.
Bluetti EB70S Portable Power Station
Next, we have the bigger variant of the Bluetti power stations in our take on Bluetti EB55 vs. EB70S.
As you can see, EB70S is also a 700-watt power station with a surge of 1400 watts. It differs from its younger sibling with a higher-capacity battery pack. That is a 716Wh LiFePO4 unit.
Apart from design and inverter, there are more similarities between the two compact products. For example, the EB70S also features four pure sine wave AC outlets to deliver 110V US standard power to run your essential appliances.
When it comes to the other charging options, it features two 100W Type-C PD ports and only two units of 5V/3A standard USB-A ports, different from the EB55’s four units.
Two regular DC sockets, a 12V/10A carport, and a 15W wireless charger are other charging options.
What’s more, it also has the same options for charging. It has a 200-watt AC adapter and a 200-watt solar input. You can combine these two to ensure faster charging in under three hours.
Full charging from a carport is possible in three hours. Or you can also get it recharged from a gas generator in emergencies, like with its younger sibling.
Compatible Solar Charger
For both machines, the Bluetti PV200 solar charger is the best choice. It is a 200-watt folding solar charger with a higher conversion efficiency. This can offer the maximum solar output the Bluetti power stations require.
The solar charger can deliver a DC output of 19.8 volts and an open-circuit voltage of 24 volts. It is foldable into a small, briefcase-style form; its folded size is 20.7 x 20.5 in, and the weight is just 14.3 lbs.
The built-in kickstands help you place it anywhere upright to get the most out of the sunlight. Once folded down, you can carry it on its strong handles anywhere quite easily.
The EB55 vs. EB70S: What to Buy
There will be little confusion in choosing between these two devices. They are the same machines with different battery packs. You get different storage capacities, with most of the other features being the same.
In terms of price, the EB55 is $100 cheaper than its sibling. You get it for $499, while the EB70S is available for $599 before any discount. You can check out the above links to get the best deals of the moment from the vendor.
When it comes to size, the EB55 measures 10.94 x 7.87 x 7.79 in, and it weighs 16.5 lbs. Meanwhile, the EB70S has a size of 12.6 x 8.5 x 8.7 in, and its weight is slightly higher at 21.4 lbs.
Both models are available in several attractive colors, including gray, blue, red, and more.
The Bluetti EB3A is an ultra-portable and compact solar power station with an LFP battery. Bluetti announced the smallest 268Wh LiFePO4 solar power station at CES 2022, apart from the Bluetti NA300 and AC500. The device hit stores in June 2022 with a selling price of around $250.
Bluetti EB3A Small Solar Generator
Branded as the Bluetti EB3A solar generator, it is the brand’s entry-level power station with an inverter of 600 watts, a solar charging speed of 200 watts, and a turbo-charging mode of 430 watts. Compared to the AC50S and EB55 compact power stations, it has a long-life LFP battery and a powerful inverter.
Bluetti EB3A Solar Generator
The EB3A is, of course, a lightweight and compact solar power station. With a weight of just 10 pounds, you can carry it anywhere as it is very travel-friendly. Along with its light size, it is going to be one of the smallest power stations with a LifePO4 battery pack on the market.
The ‘A’ in its branding of EB3A looks to refer to its “advanced” profile over the other Bluetti power stations. Thus, it has several refined and enhanced features, like a revamped display screen and turbo-charging, which will make it a more reliable source for off-grid, RVing, and camping requirements.
The little power station has an MPPT charging input of 200 watts, which can make it charge in 2.5 hours under a bright sun. So a single piece of Bluetti PV200 can be a cool combo with it, for sure.
Meanwhile, it can be charged at a standard rate of 286 watts and a rather faster 430 watts in its turbo-charging mode. In the latter mode, it will take only half an hour to charge from 0% to 80%.
Like many of the new Bluetti power stations, it incorporates an AC adapter, so you don’t need to carry the burden of a power brick. By the way, it works with the Bluetti App via Bluetooth, which gives you full control of the device. It also supports OTA upgrades.
Bluetti EB3A Vs. Bluetti AC50S
Besides the EB55, Bluetti has the AC50S, another compact model in its collection of solar power stations. Different from the EB3A, the AC50S has a lithium battery, but it has a better capacity of 500 Ah.
That is, if you are looking at buying a big-capacity compact power station model, the AC50S looks like an intelligent choice, and it has 300 watts of AC power, which is half of the EBA3’s 600-watt inverter.
In terms of price, you will get the AC50S at the same price as the EB30A, however. The EB3A has a retail price of $299 without any discounts, while the AC50S has a discounted price of $299.
Of course, the AC50S features a small and lighter design. With a weight of 9.8 lbs, it shares the same weight as the EB30A. Including a 12V regulated DC port and two AC sockets, it features 11 charging outlets overall.
In short, the key differences it has over the EB3A are its high-capacity lithium battery pack and cheaper price. The limitations include a 450-watt peak power limit and limited charging cycles.
Bluetti EB3A vs. Bluetti EB55
As you see, when we have EB3A as the entry-level variant of the Bluetti line-up, EB55 is the next model in the brand’s series of solar power stations.
As you see, the EB55 is also an LFP power station, and it has a battery of 537 Wh capacity, a 700-watt inverter with a surge capacity of 1400 watts, and as many as four 110V AC sockets.
As you already know, the EB55 features a 200-watt AC input and a 200-watt MPPT solar charger inside. It sports 13 charging outlets, including AC sockets, a single 100W Type-C PD port, and dual wireless chargers.
In terms of size, the EB55 has dimensions of 10.94 x 7.87 x 7.79 in, and it weighs 16.5 lbs, which is six lbs heavier than the entry-level EB3A solar generator.
The AC60 is a 403 Wh, 600-watt ultra-portable solar power station, and you can crank it up to 2015 Wh with a pair of B80 battery packs.
Thanks to its IP65 rating, it is a water- and dust-proof portable battery, which certainly makes it different from all other small Bluetti power stations.
The combo of AC60 and B80, as Bluetti highlights, is to become the first small solar power station from the brand with modular features. You will be able to add extra storage capacity to the AC60 using the B80, just as you can with the AC300 and AC500.
