What is the Bluetti EB3A?

The Bluetti EB3A is one of the smallest portable power stations that Bluetti has to offer. It’s a compact and budget-friendly solar generator to charge small appliances and electronics during outdoor activities. We took the EB3A on a four day camping trip in the snow and tested this compact off-grid power solution both in the field and in our “lab”.

Features of the Bluetti EB3A

The Bluetti EB3A is built with modern power station technology, ensuring reliable performance in various scenarios. Let’s take a closer look at its key features:

Power Output

The Bluetti EB3A provides a total of 600W continuous power and can surge up to 1,200W for short bursts, allowing it to power small appliances, essential gadgets, and medical equipment. The pure sine wave inverter ensures safe and stable electricity, making it suitable even for sensitive electronics like laptops and CPAP machines.

Battery

The Bluetti EB3A comes with a 268.8Wh LFP battery. Thanks to this LiFePO4 chemistry (LFP) it can provide over 2500 life cycles before degrading to 80% of its original capacity. Hence, this translates to years of reliable off-grid power on many adventurous trips. When we received the EB3A it was charged at 56%. That’s exactly the way we want it to preserve the battery during long-term storage. The ideal battery % for long-term storage should be between 40% to 60% and it should be recharged every 3-6 months. So well done Bluetti!

A solar generator with 268.8Wh battery capacity is not much. We were curious how long it would last when we took it on a 4 day skiing trip with the camper van. Especially in those cold temperatures of up to 5°F (-15°C). We used it mainly to dry our ski boots with boot dryers for 3 nights. Every evening we switched on the boot dryers for several hours and switched them off when we went to sleep. In the morning we switched them back on for approximately 2 hours. Additionally, we charged a phone and a power bank once. At the end of the trip we came home with still 24% on the battery, without needing to recharge it during the trip! Of course, we used it economical but still we did not expect that it would last the entire trip without a recharge. We could have easily charged a phone a couple of times more and some other small electronics.

Ports & Expandability

The EB3A comes with a variety of output options, making it suitable for charging multiple devices simultaneously:

Outputs

• 2x AC Outlets (120V/5A, 600W total)
• 1x USB-C (100W max)
• 2x USB-A (5V/3A each)
• 1x 12V/10A Car Outlet
• 2x DC 5521 (12V/10A each)
• 1x Wireless Charging Pad (15W max)

Inputs

• 1x MPPT 12-28V DC / 8.5A
• AC 220-240V / 4A

Note that the European version of the EB3A will only have 1 AC outlet since the European socket is larger compared to the American socket. Therefore, the American version has 2 AC outlets.

On such a small power station it’s nice to see the USB-C 100W outlet. It’s in particular convenient to charge modern laptops etc. We used the USB-A ports during our ski trip to charge the power bank and smartphone. It worked perfectly. Another nice thing the EB3A has to offer is the wireless charging pad on the top. Things can get a little bit messy after a few days in a camper van and especially cables tend to get missing. No problem, we just put our phone on the EB3A and got it juiced backup. Further, there is not much to say about the different ports on this model. For a portable power station this size it’s more than equipped enough.

Unlike some larger models, the EB3A does not support battery expansion, meaning users who need more power may have to consider higher-capacity models like the Bluetti AC180.

Design & Build

The Bluetti EB3A is compact and lightweight, weighing only 10.14 lbs (4.6 kg). Its dimensions (10.04 × 7.09 × 7.20 inches) make it easy to carry, and the integrated handle allows for effortless portability.

The casing is made of durable plastic, designed to withstand minor bumps and scratches. However, while the unit is not waterproof, it can handle light splashes and outdoor environments if properly shielded. Although, the casing looks durable, the only thing we are concerned about is the back of the unit. It looks like the back panel of the case could’ve been made a bit more robust. It’s the only side of the case that will bend a bit when pushing it. If the case would break due to a puncture or a fall it will probably be at the back.

The EB3A is very easy to use. All controls and ports (inputs & outputs) are on the front and divided into 4 zones: DC outputs, AC outputs, inputs and light. Each output zone has a button to switch the zone on and off. Make sure you switch for example the AC zone off after powering your devices because otherwise the inverter will keep on consuming power from your battery even if you aren’t powering anything. Further, the LED screen is very convenient and easy to read: Input (Watts) – Battery % – Output (Watts). A notable feature is the silent operation, which makes it perfect for indoor use, whether in a tent or a bedroom.

If we are critical about the EB3A then we would say that it doesn’t have a main “on and off button”. In fact it has 3 “on and off buttons”: every zone button can turn this solar generator on and off which can be a bit confusing at the beginning. In addition, to activate the wireless charging pad you need to switch on the DC output zone, which took a while to figure that out. And lastly the light… why for the love of god would you want a light on a portable power station? Of course, it’s very compact and portable but still there are better alternatives available to lighten up the dark such as a flashlight or a head lamp. Why not use this space to offer an extra AC outlet or something else?

App and UPS

With the Bluetti App you can control the EB3A via your phone. Nothing crazy here. You can switch the “zones” on and off, switch the power station off, change modes, and see how much Watts are going in or out and how much battery you have left. Hence, quite basic but it works properly. The EB3A also has a UPS function which will turn on when you are powering something while the power station is also charging through AC or solar. Therefore, you can use it for a CPAP machine, for example. If grid power would fail the EB3A will take over immediately and power your cpap machine.

Portability

With its lightweight build and compact size, the EB3A is highly portable. The unit is designed for easy transport, making it ideal for camping, road trips, and small-scale emergency power needs. It easily fits in a small space like under the seat of a camper van. The handle can be folded in to the top when not carrying so it won’t take any additional space.

Who is Bluetti EB3A useful for?

• Home backup power during shorter outages.
• Camping and outdoor adventures.
• Charging laptops, phones, and small appliances.
• Off-grid workstations and photography setups.

How did we test?

We took the EB3A on a skiing trip with a camper van and tested it for 4 days. Field tests like this can give a lot of valuable information about the performance of a portable power station. However, influencing factors can play a role on performance such as temperature, humidity,… Therefore, we also test every solar generator with a set of standardized test in our lab to assess the EB3A’s performance under stable surroundings:

• AC Discharge Test
• Moderate Load Test
• Heavy Load Test
• Extreme Load Test
• AC Charge Test
• Solar Charging Test

AC Discharge Test

We connected a 85W laptop charger and let the unit run until depletion. To be sure our computer wasn’t going into sleeping mode we put on the “Ultimate Mr. bean compilation 5 hours non-stop” on YouTube. We saw very volatile Watt outputs but most of the time between 20W-30W. To give our laptop’s CPU some extra work (= higher energy consumption), we started Adobe Lightroom on our computer, which is “heavy” photo editing software.

The EB3A powered our laptop for 7 hours 15 minutes until the 268Wh battery ran empty. In terms of working days this means you could work on your laptop for 1 working day off grid with the EB3A without needing to recharge it. A pretty good result. However, if we look at how many Watt-hours were delivered by the EB3A, we only read 150Wh on our energy meter instead of the advertised 268Wh. This means that when using low loads for a longer period the efficiency of the EB3A is only 55%. In other words, the capacity will be 150Wh instead of 268Wh. Where did the other Watt-hours go to? The inverter! A bit disappointing yet somewhat logical that the lower the load, the longer the operational time will be and the more energy the inverter itself will consume. However, we’ve seen models from Bluetti where the efficiency was a lot higher, even for small loads.

Moderate Load Test

In this test we used a 400W baby cooker. This is a device that can steam and mix food to make a meal for your baby. We wanted to see if we could prepare a baby meal without grid power. Here are the test results:

The EB3A did a perfect job. The steamer was on for 21 min and then we used the mixer for 20 seconds and we still had 48% of the battery left. The Bluetti EB3A was able to power this 400W device effortless. When the fans turned on we measured how loud it was. We’ve measured 47dB which you can compare with whispering. This was only measured 20 cm from the unit. We also measured a better efficiency during this test which is logical because the baby cooker was a higher load.

Heavy Load Test

Let’s put some more weight on the EB3A’s shoulders. We took a small kettle of 540W and a JBL charge 5 speaker, plugged it into the EB3A and turned on both the AC and DC zones. The EB3A passed the test without any problem.

Extreme Load Test

For our next test we wanted to check how good the safety mechanisms of the “battery management system” work. Therefore, we plugged a kettle demanding 1600W, which is way too high for the EB3A. Almost immediately when we turned on the Kettle it automatically turned off again because of the BMS system of the Bluetti instantly taking over and showing “overload” on the screen. Test passed!

AC Charge Test

The EB3A has 3 charging modes: standard, silent and turbo. Turbo means that it will charge at its maximum input of 350W. However, use this mode only if necessary since it will reduce the lifespan of the battery. Silent mode charges at 100W input and is ideal if you have this power station in the same space were you sleep and you can leave it plugged to the grid for a few hours. You can change these modes in the Bluetti app. For our AC charge test we used the standard mode. The battery was totally drained when we started and we measured input of approximately 270W during the entire time. It took approximately 1 hour and 15 minutes to get it back to 100%. During the process the fans turned on a couple of times. The maximum temperature we’ve measured was 87.1°F (30°C). We also measured that the EB3A drew 290Wh instead of 268Wh during the test so this means that 7,5% of energy was lost.

However, we must mention that during our testing procedure, when we recharged the EB3A for the 2nd time we noticed a loose connection between our AC input port and the AC charger/cable. This led to a malfunction of the charging procedure where the screen showed that the EB3A was charging from 48% to 94% in just a few seconds. We unplugged it and made sure the connection was stable by lifting the cable up and then let it recharge until it was back at 100% (which took a lot longer than normal for 6%). After that it was fine but the loose connection stays a problem. We’ll give an update on this when we hear back from Bluetti about this issue.

We plugged in a 200W Bluetti solar panel and got 165W input on a sunny but partly cloudy day.
