We analyze the Bluetti EB55, solar station + portable solar panel

Surely one of the products that catches my attention the most and that I like to try the most, solar stations or batteries, today we are analyzing the Bluetti EB55.

Before I received the portable solar panel and battery, I checked the reviews on your website and Amazon, and they were all very positive. My expectations have increased. At the time of writing this review, I haven’t used the set to its full capacity, but I really like it. Surely this is a device that I will use for many years.



If you look on their website, you will see that the basic set comes with a single battery, or with a battery and a portable photovoltaic panel.

I am testing the battery and a photovoltaic solar panel. Currently, I don’t need two photovoltaic panels for this battery.

When the Bluetti arrived it was well packed in two boxes. The solar panel was in one, wrapped in bubble wrap, and the battery was in another, wrapped in protective cardboard.

The solar panel has a sleek design and I immediately unfolded it to check it out. Its finish is good. Deploying and closing it is quite simple.

On one side of the solar panel there is a zippered pocket, and it contains the cable (permanently attached to one side of the panel) that connects it to the battery for charging. There is also a splitter that allows two solar panels to be connected to the battery at the same time.

It incorporates folding supports to be able to keep the panel upright, keeping it tilted. Everything seems to be quite stable without strong winds. Another option is to hang the panel in a vertical position with the two rings it incorporates at one of its ends.

The box with the battery was heavy (not so heavy that you couldn’t lift it), it seems to be durable. It incorporates a handle at the top, which facilitates its transport.

There was also a booklet, but not an actual instruction manual, although I’m not sure step-by-step instructions are needed to get the system up and running.

First impressions.

My first impressions were positive.

The battery looks and feels sturdy. It is a lithium-ion battery surrounded by strong plastic. I don’t expect it to hold up if dropped from a height, but I’m sure it will take bumps and drops. It’s not something that’s going to take a lot of wear and tear with regular use, so I expect it to last a long time.

Everything is located on the front, pressing the button on the screen to check that the charge level was at 60% at the time of delivery. The input connector matched the cable from the solar panel, and all the outputs are what I’ve used before. Everything seemed intuitive.

On the back it incorporates an LED light that can really be very useful, especially for those who are going to use it outdoors.

First impressions were excellent.

How we use it.

I didn’t read any manual before using the solar panel and battery, and I didn’t need it. Everything is intuitive and easy.

The panel unfolds and there is a bracket on each half that also unfolds to hold the panel stable. I took the cable from the back of the solar panel and connected it to the only input on the front of the battery that would fit. The panel has started charging the battery. As simple as that.

When it was time to use the battery charge, I plugged it into the socket on the front (the first time was the string lights on the mains socket), and they lit up. I then tried with the solar panel and the lights plugged in at the same time.

All you have to do is press the plug button above the outlet (AC or DC) to power it up.

The panel charged at 156W when in direct sunlight.

Prolonged use.

You can refer to the tables below for more information on the operating time of certain appliances and electronic devices.

I tried a few to see how long the battery would last.

Some examples with laptops, smartphones and tablets.

Who could use it?

If you’re worried about the power going out, this will hold enough charge to keep your essentials running until the power returns.

In any type of house, flat or apartment, it can be very useful in the event of a power failure. You can also expand your solar station setup by purchasing additional batteries and panels depending on the size of your home and your power needs. The ideal would be to have a terrace with direct sun to be able to take advantage of the solar panel.

Power outages are rarely expected, but the Bluetti EB55 can hold a charge for up to a year, so you’ll never be caught out. Plus, you can quickly install the solar panel and get instant power if you get caught off guard.

This can be especially important for those who work from home. You can charge your devices and continue working during power outages. Worried about things in your fridge going bad? Connect it to the battery. It’s dark and you have no light? Where is the battery?

If you have a garden. you can use it to run lights or any other devices you want to use without running wires. The best of all is that both indoors and outdoors the energy is free and if you charge it with the solar panel it is also sustainable.

Ideal for those who enjoy outdoor adventures, such as camping.

I can think of 1,001 uses for this battery.

The battery and solar panel are well designed, charge efficiently and quickly, and provide plenty of power. They are both easy to carry and I know they will last a long time.
