Our experience with Power Queen 12.8V 100Ah LifePO4 battery

, by Sally Zhuang, 5 min reading time

Luckily we had a test of Power Queen 12.8V 100Ah Mini LifePO4 battery. When we unpacked it, we were impressed by the quality of the materials and the aesthetics of the battery. This LiFePO4 battery offers a large capacity for its price and is particularly lighter compared to lead-acid batteries.

After using the LFP battery during a road trip, we can say that the LiFePO4 battery is ideal for our converted van with power.

Our capacity test confirmed Power Queen's information and underlined its transparency and reliability. We particularly value the LiFePO4 technology for its longevity and efficiency.

If you would like to learn more about our experience with the Power Queen solar battery, read our full article. Otherwise, you will find a brief summary of our experiences here.

First impressions

LiFePO4 Batterie 100Ah Mini

Our Power Queen lithium battery arrived after a week of waiting. We first opened the package. The instructions for use in German and English greeted us. We were also gifted with some cool stickers.

The battery, well protected by Styrofoam and plastic, turned out to be a modern and robust device. Details like color-coded poles and a sturdy carrying strap reinforced our positive first impression.

Upon unboxing, this 8.96kg LFP battery demonstrated its portability and impressive 1280W capacity. The compact size demonstrates Power Queen's efforts to optimize cell layout and energy density. It is the ideal companion for van adventures and combines energy autonomy and handiness. We were excited and ready to test this battery!

Functions of the LiFePO4 100Ah Mini Battery

100Ah LiFePO4 Batterie Mini Power Queen

The Power Queen 12.8V 100Ah Mini LifePO4 battery is a true power plant. Thanks to its ability to deliver a continuous current of 100A, it can power multiple devices simultaneously with up to 1280W. Even energy-hungry devices such as a hairdryer or a blender can be operated without any problems.

This 100Ah mini solar battery can even reach a peak current of 280 A for 5 seconds. This is raw energy at your service! However, it is unlikely that you will need all of the power at once.

This is where Power Queen's exceptional energy management comes into play. It offers a usable capacity of 100Ah, meaning it can deliver 1280Wh of energy. That's more than enough to power a laptop, refrigerator, lights, smartphone, and more on long trips.

Since we are digital nomads, we use the battery for power:

- An inverter 12V - 230V

- Two laptops

- A 4G router

- Two mobile phones

- A drone

- Two LED lamps

- And other occasional small devices

With a capacity of 100Ah and a 385W solar module, we are able to supply ourselves completely with electricity.

However, to extend the life of your LiFePO4 100Ah mini battery, we advise you not to discharge it more than 70% - 80%. This means you still have an impressive reserve of 80Ah that you can use as you wish!

Practical application and capacity test

Determine your energy needs

Before you invest in the Power Queen LiFePO4 battery, you should be clear about your daily energy consumption. You can estimate this by listing all your electrical devices, their performance and how long they are used each day.

To simplify this calculation, we have developed an online tool that is accessible with just one click. Just visit our blog "Objective van life" and click on "Electric Simulator" in the menu.

In our case the daily consumption was around 750 Wh, so a 100Ah LiFePO4 battery was suitable.

Testing the actual battery capacity

Living off the grid requires a reliable source of energy. To verify the Power Queen's true capacity, we conducted a rigorous test that included a full battery charge, a full discharge through daily use of typical van devices, and constant battery temperature monitoring.

For the test, we used a 385W solar panel, a 500W inverter and various battery discharging devices.

We used two laptops, two phones, multiple lights, a Kindle e-reader, and even a drone every day. In total we used almost 1210Wh over two days.

Test Results

Despite intensive use, the battery temperature was never above 40℃, well below the upper limit of 60℃. Our test confirmed that the Power Queen's actual capacity is between 1205 and 1220Wh, which is about 95% of the manufacturer's stated capacity.

Our conclusion is that the Power Queen LiFePO4 battery offers exceptional performance for its price. It provided consistent power to all of our devices without overheating. If you are looking for a reliable battery for your van, the Power Queen seems to be an excellent choice.

To this day we test the battery daily to update our article.

Positive aspects of the Power Queen LiFePO4 Battery

Power Queen 12.8V 100Ah Mini LifePO4 Battery offers several features that we really appreciate. Their large capacity at a competitive price is certainly a big advantage. With a retail price of €469.99, this battery offers excellent value for money for anyone planning long holidays or full-time van life.

Their light weight is also an undeniable strength. Compared to lead-acid batteries, it offers significant weight savings, making installation in the vehicle easier. Before choosing the Power Queen, we tried a lithium battery, which was much heavier, and a GEL battery, which was almost three times as heavy.

Finally, we particularly appreciate the fact that the Power Queen uses LiFePO4 technology. These LiFePO4 100Ah batteries are safer, last longer and hold their charge more efficiently than classic lithium-ion batteries.


In summary, it can be said that Power Queen 12.8V 100Ah Mini LifePO4 battery impresses with its impressive properties and its excellent price-performance ratio. Whether for an extended trip or a nomadic van life, it proves to be a smart choice. Their low weight compared to other batteries on the market makes installation and handling easier.

It is also characterized by the use of LiFePO4 technology, which stands for safety, durability and energy efficiency. Although the initial cost may seem high compared to GEL or AGM batteries, the long-term return on investment is undeniable.

After trying and testing the Power Queen, we can highly recommend it to anyone looking for a reliable and long-lasting battery for their adventures.
