Portable power stations were once a bulky and expensive way to keep electrical equipment running, but in recent years have become smaller, sleeker, and less expensive for everyday users. No longer just for backcountry campers and preppers, they now come in a variety of sizes and capacities, with a variety of features and prices.
Bluetti is a good example, offering more than a dozen different models ranging from 300W all the way up to 2400W. In this review, we’re looking at one of their mid-range options: 800W EB70S Portable Power Station.
I spent several months testing the power station, testing its performance both at home and outdoors. I didn’t have the opportunity to take it on a full-scale camping trip during that time, but I’ll update this review when that changes.
Here’s how it performed in my testing, and what I found to be the strengths and weaknesses of this particular unit. I’ll go over its most notable features, and finally what I think the EB70S is best suited for.
OK, let’s get started!
Features and Box Contents


First, let’s cover the basic features and what’s included in the box.
BLUETTI EB70S has:
- 4 AC outputs (120V/20A)
- 2 USB-A outputs (5V/3A)
- 1 car charger/accessory port (12V/10A)
- 2 DC outputs (12V/10A)
- 2 USB C PD outputs (100W)
- 1 Qi wireless charging pad (15W)
- 1 LED light with full flash, half flash and SOS flash modes
It measures 12.6 x 8.5 x 8.7 inches and weighs 21.4 pounds. This is pretty standard for a power station of this capacity and output, although not the smallest or lightest I’ve come across in this market.
Almost all the interesting stuff is up front: the only exception is the wireless charging pad in front of the fold-out carry handle on top of the device. The LED screen conveys basic information such as battery capacity and input/output power.
What’s in the box:
- BLUETTI EB70S Portable Power Station
- AC adapter and charging cable
- car charging cable
- Solar charging cable
- Instructions and warranty card
Note that the standard version of this power station does not come with a solar panel, although it comes with a solar charging cable in the box. You can add a 120W or 200W kit at a discount at the time of purchase, or purchase it later if needed. It uses standard MC4 connectors.
The device features a 716Wh LiFePO4 battery that is rated to last 2,500 charge cycles while still retaining 80% of maximum capacity. The specs show charging takes 3-4 hours using a 200W charger, which is consistent with my testing: using a typical household outlet, the battery took 3 hours and 40 minutes to charge from empty.
The optional 200W solar panel is expected to take longer, around 4.5 hours, or 7-8 hours if you charge using the 12V car output. This may sound like it will take a while, but it still means you can fully charge the EB70S during a day’s driving and then use it to power your gear at night.
What are the advantages of EB70S?
Visually appealing design


I love the look of all Bluetti products: they are sleeker and sleeker than many other brands. The power station I received is a soft light blue, which is more attractive than other brands’ emergency bright orange and rough edges.
The unit also comes in turquoise and solid gray versions, the latter of which is especially nice and neutral if you’re going to use this regular color in your home and want it to be less eye-catching.
But remember, no matter what color you choose for your device, if you also have a solar panel, its handle will always be light blue.
Lithium phosphate battery
All of Bluetti’s power stations, including the unit reviewed here, use lithium-ion phosphate (LiFePO4) batteries. This is in stark contrast to the lithium-ion batteries used by other brands, especially in cheaper models.
LiFePO4 batteries have a significantly longer service life, making them more suitable for power stations like this which are likely to last for many years. The battery in the EB70S is rated to last for more than 2,500 charge cycles while retaining at least 80% of its maximum capacity.
The only real drawback to this type of battery is that it doesn’t have the same energy density as lithium-ion batteries, which means devices that use it tend to be larger and heavier than other batteries.
There are far fewer issues with a portable power station than a phone or tablet: I’d rather it last a few years longer than be a little smaller or lighter. Bluetti made the right choice here.
Mid-range price
For the price, Bluetti’s product is mid-range compared to other portable power stations I’ve reviewed.
The price point is not as high as the market leaders Jackery’s equipment Not as low as Affordable Power Stations from GRECELL. If you pay full price, the EB70S sells for about $650, but it’s often on sale.
If you’re in the market, pay special attention to Prime Day, Black Friday and Boxing Day deals. For example, on Prime Day this year, this particular unit is almost half off, selling for $369.
Is there anything not so good about it?
Battery level display
The LCD screen looks nice and is easy to read and understand, but it only shows a few bars of battery life rather than the exact percentage remaining.


Remaining battery life is divided into five columns: 20%, 40%, 60%, 80% and 100%, with nothing in between. At 100%, this doesn’t matter, but the display makes it difficult to understand how quickly the battery is draining.
The last column is the worst because You have no way of knowing if the battery charge is between 20% – 1% until the power station is depleted.
The display light also turns off after 20 seconds – a bit too fast for my taste. Other devices I’ve tested dim first to save battery, but the display doesn’t immediately go completely black.
That said, I’m probably more aware of this because I’m logging various input and output ranges for testing. Press any button to turn the display light back on.
Front flashlight


The front-facing flashlight is an unusual choice and not very good from a user experience perspective. The light itself works very well, with at least two brightness settings and a flashing SOS feature for emergencies.
The problem with leaving the flashlight in place is that it is very inconvenient to use when you are carrying the unit because the handle on top of the unit runs horizontally along the top of the unit.
Like most other portable power banks, the side-facing light allows you to carry the charging station via a handle on the side, with the light facing forward in the direction you’re looking. This is a more sensible approach for what you’re actually using the flashlight for.
Additionally, mounting the light on the front like this means that whenever you turn it on, it shines directly into your eyes. It’s not the end of the world, but again, it’s an avoidable problem.
Other Bluetti options
One interesting aspect of the Bluetti brand is that they have a huge range of portable power station options: at the time of writing, the 800W EB70S is one of 13 different models they offer.
Starting at the low end, they have a 300W model that goes for less than $300 full price (again, it’s often on sale) and even includes one of those long-lasting LiFePO4 batteries I mentioned earlier. Other models have maximum output power from 600W to 2400W and capacities from 204Wh to 2048Wh.
That means a Bluetti power station can fit nearly all your needs, whether you just want a smaller power station for your backyard or camper, or you need a heavy-duty power station for multi-day outdoor adventures.
You can even replace the backup battery in most models to extend runtime even further. If you want to do this, just double-check that the model you’re looking at supports this feature: all but the lowest-end models do.
