So you decided to research a portable power station like the Bluetti EB3A here.
This is a small power bank with various outlets but it is not that "small" as a "power bank" but it is as a power station it's about as small as you can get with power stations at under 300Wh (watt hours) of power to use its 268Wh. That's about a day of use. Can also be used as a pass through such as if needing to charge multiple things at once. This can be re-charged with a wall plug, cigarette or solar panel.

This review is a mix of 2 other recent posts about 12V vs 24V and fuses and a mini fridge and the OBD2 port fuse connection to the 12V cigarette lighter ports. Sections taken out the info combined here now.

It has a 12V DC port (cigarette), two USB-A ports (older flat rectangular shape), and 1 USB-C port, and two 12V wall outlet plug ports. So you can find a way to charge your things with this.
On the eb3a I'm getting 100 watts directly from the car battery with an extra long cigarette plug port. It's 102 to 103 with car running.
Drops to 35 mainly but saw it at 47 watts when not running when first turn off engine then drops to about 35 watts.
It's about as much power as a solar panels worth of power to my power station at 100 watts. Could be 147 watts is the EB3A cap anyways.
The Bluetti EB3A (discontinued) in 2026 now.
It's a 600watt, 268Wh power station ((this is how much power it can output from the battery charge it has in total it's 268 watt hours of power at peak 600 watts (things like laptops use 40 watts not 600 continuous FYI) but it can momentarily do more as in when an appliance first starts could be 1000 watts to start then less running it)). Likely won't start a microwave and be able to run it if it could handle the surge spike. Need more watts and more surge power on start up so eb3a is good for laptops, etc... mini fridge. [Link]
Has AC and DC power option and the USB connections. AC as in wall outlet and DC for cigarette lighter 12v plug port. The AC uses an "inverter" so that draws power to use so it is best to use the 12v cigarette port for DC power. If shopping items to use look for those that come with both cables types.
Can be charged with wall, cigarette or solar panel. MPPT plug port. You can't plug a cigarette connection to input to it to charge, instead the cigarette plug goes into the cars cigarette plug then there is the MPPT plug port on the eb3a. Little circle plug hole. You can output from the eb3a with a cigarette connection in top left for DC power that is plugged into the eb3a then into your tech. To charge off the eb3a or as a pass through if getting wall or solar power or direct from battery. The lower left is the port to charge the eb3a with solar or cigarette and then the wall AC cable plugs into the square looking cover on the port. Need to lift see picture above.
In about ten minutes got 8% charge so from 1% to 9%. At 100 watts. Has a 30A fuse, one connected near the battery in a little storage box inline and 2 spare. It's up to 17% in time took make this blog post. So 20 minutes.

600 watt portable power station is it better to run a portable fridge on AC or DC?
It is better to run a portable fridge on DC (12V cigarette lighter port) rather than AC on the Bluetti EB3A.
AC = Alternating Current
DC = Direct Current
Why DC is Better::
No Inverter Drain: Using AC requires the Bluetti EB3A to turn on its internal inverter. The inverter alone wastes about 10 to 15 watts of continuous power just to stay awake.
Direct Efficiency: Portable fridges run on 12V DC compressors naturally. Plugging into the 12V DC cigarette port skips the conversion step and saves battery life.
Maximized Runtime: Because the EB3A has a small 268Wh capacity, saving those extra watts means your fridge will run significantly longer before the power station dies.
Tips for Best Results::
Pre-chill the fridge: Cool the fridge down using wall power at home before you head out.
Use Eco Mode: Turn on the fridge's internal eco mode if it has one so it draws less power once cold.
Keep it shaded: Keep the power station and fridge out of direct sun to reduce compressor cycle times.

Yes, the Bluetti EB3A is a solid, highly regarded compact portable power station, particularly strong on value, portability, output power for its size, and battery longevity—though it has clear limitations and has largely been discontinued in favor of successors like the Elite 30 V2.bd9e81
Forbes
Key Specs
Capacity: 268.8Wh LiFePO4 battery (rated for 2,500+ cycles to 80% capacity—far better longevity and safety than typical NMC Li-ion).
Output: 600W continuous pure sine wave AC (1,200W surge), with 2 AC outlets (region-dependent), 1x 100W USB-C PD, 2x USB-A (5V/3A), 12V car port, 2x DC5521 ports, and a 15W wireless charging pad.
Charging: Very fast—up to ~350W AC (turbo, ~1–1.5 hours full or 0–80% in ~45 minutes in testing), up to 200W solar (MPPT), car, or dual input up to ~430W.
Portability: ~10.1 lbs (4.6 kg), compact (~10 x 7 x 7 inches), with a handle.
Other: App control (Bluetooth), UPS/EPS mode (≤20 ms switchover in many reports), pass-through charging, LED light on some units.d0b0f9

It can run small appliances, charge phones/laptops many times over, power a mini-fridge or fan for several hours, keep a TV going for a few hours, or handle short outages for essentials like routers/modems. Real-world tests often show good performance for light-to-moderate loads (e.g., camping, short blackouts, or charging tech), though efficiency and runtime estimates can vary and the battery percentage display isn’t always perfectly accurate.fcf1c5
Forbes
Pros
Excellent power-to-size/weight ratio—600W from a ~10 lb unit is impressive and beats many competitors in the same capacity class (e.g., higher continuous output than some Anker models).
Fast recharging and flexible inputs (AC + solar dual charging is a standout).
Durable LiFePO4 chemistry for long cycle life.
Feature-rich for the price (wireless pad, app, multiple ports, pure sine wave for sensitive electronics).
Strong value when available (often ~$200–300 range historically; frequently discounted).aad557
Back2gaming
Cons and Limitations
Modest capacity—best for short outages, light camping, or device charging rather than extended off-grid or high-draw appliances (it won’t power a full gaming rig or large fridge for long).
Some reported quirks: occasional overheating during charging, fan noise, inaccurate remaining-time estimates, basic USB-A ports, and occasional UPS mode issues (e.g., false overload under light loads in some user reports).
2-year warranty (shorter than some rivals’ 5 years).
No capacity expansion.
Plastic build feels okay but not premium; solar panels/cables often sold separately.e344d0

Overall Verdict
It’s a good (often “excellent value”) choice if you need a lightweight, fast-charging unit for phones, laptops, small appliances, camping, or emergency backup of essentials. Reviewers frequently praised it as one of the better compact options in its class for the combination of output, speed, and LiFePO4 durability.e47648

Note on availability (as of 2026): The EB3A has been discontinued by Bluetti in many markets. Its closest successor is the Elite 30 V2 (similar size/weight, ~288Wh, 600W, often improved UPS, quieter, longer warranty, and comparable or better pricing). If buying new, check current stock/pricing and consider the Elite 30 V2 or slightly larger options like the AC70 for more capacity if your needs grow. Used or remaining new EB3A units can still offer strong value if found at a good price.2749c5

For most light portable/backup uses, yes—it’s a good pick (or was, and the successor continues the strengths). Match it to your expected loads and runtime needs.

Today, the DC Cable stopped powering the fridge but the AC worked...
Pure cable failure is the least likely unless the cable is physically damaged, melted, or has a bad plug.
The fridge’s startup surge is a frequent trigger.
The EB3A itself going into a protective “SHORT” state (especially after deep discharge) is the single most reported issue when people power portable fridges from it.
