Test: Powerstation Bluetti EB70 PowerOak + PV200 Solarpanel

Whether you’re car camping, in a tent, around a caravan or at home, the portable Bluetti EB70 has a lot to offer.

This powerhouse will easily charge all your essential devices for communication or night lighting.

If you also like to work with the laptop independently of the mains, then the EB70 in combination with the 200 watt solar panel PV200 will give you a lot of pleasure.

Read my review now and you’ll find out if the Bluetti EB70 is something for you too.

What I think of the Bluetti EB70 – the EB70 in the test

I am writing this review on my laptop in the middle of a field in Brandenburg. The sun doesn’t shine all the time in September and it’s about 16 degrees.

Perfect for my final test of the Bluetti EB70 PowerOak power station.

In the last few years, I have repeatedly tested different power stations, from simple small power banks that provide a few charges for a smartphone, to power stations that are designed for a life independent of the mains.

I’ve found portability, a large battery capacity, performance and the ability to charge a battery pack via a solar panel on the go is the perfect combo for me.

And the Bluetti EB70 power station in combination with the Bluetti PV200 solar panel (200 W) is possibly the best I’ve tested so far.

Before my last car camping, I had already brought the power station to about 10% battery capacity. Then I connected them to the solar panel. Four hours later it was fully charged and I was able to go camping.

A balanced option between performance and portability

The Bluetti PowerOak EB70 portable power station was designed to offer a balanced option between performance and portability – and I can definitely attest to that.

You get a power station that weighs ok compared to others in the league (9.7 kg) and still packs plenty of juice with the 200 watt solar panel.

Although the 700W battery limits what you can connect, most devices you need when camping or in an emergency situation will fit on it.

The two 100W USB-C ports are definitely a must-have these days as more and more laptops accept USB-C power for charging (which is good, because that way you’re not using the regular power-hungry outlet).

The fan noise from the charger – even when just plugged in at home – might bother some of you.

For me this is negligible as the Bluetti portable power station EB70 will become a valuable part of your home or trip.

Now you know the facts and my very personal opinion about the Bluetti EB70 in combination with the solar panel.

Now read on and let’s go into even more detail.

Features of the Bluetti EB70

That interests most of you, right? What can I connect to the Bluetti EB70 Powerstation?

I already wrote it above: I think the two USB-C outputs with 100 W are awesome. Some devices from the competition don’t have that and I missed it.

That means you can power electric lights, laptops, phones, and USB devices flawlessly. For me ideal for camping, caravanning and as an emergency power source at home.

So here are the facts that Bluetti gives for the EB70:

• • 2x 1000W outputs

• • Battery capacity 716 Wh (22.4 V, 32 Ah)

• • Over 2,500 charge cycles to 80% of original capacity

• • 15W wireless charging

• • Solar and socket input maximum 200 W

• • 9.7 kg heavy

• • Integrated carrying handle

The charging times

The charging times also play a big role for me, because with some power stations you charge 8 hours and more. The values ​​that I was able to achieve here are okay for me.

• • With a maximum input power of 200W, the EB70 can be fully charged in 5-6 hours with solar panels (OCV 12-28V, 200W).

• • With an AC socket, you can charge the EB 70 in 4 – 4.5 hours

• • The power station is fully charged in 7 hours (100 W) or 4.5 hours (200 W) on a 12 V carport

Almost all portable power stations, at least those that are meant to be literally carried around, start out with a rectangular box shape.

From there, manufacturers add whatever embellishments they need to stand out from the crowd. These are often curved bodies or unusual handles.

However, the Bluetti EB70 sticks to the basics to create the most space-efficient design possible.

The device is a large polycarbonate plastic box that curves minimally at the corners and edges. Its moulded plastic handle folds flat into the body when not in use.

Except for the cover of the car charging port, nothing protrudes too much on either side of the power station. In practice, this means no space is wasted on odd angles and curves.

Despite the plastic material used throughout the Bluetti EB70’s body, the powerhouse feels sturdy and well-built.

At 9.7 kilos, the EB70 is also on the heavier side, which is not what one would expect from such a small box. On the other hand, as you learned above, Bluetti delivers well for any camping lover or people preparing for emergencies.

Speaking of emergencies, it also comes with a brilliantly bright LED flashlight, which thankfully is on the front. No more trying to awkwardly aim the light like a gigantic and heavy flashlight.

Battery and charging

The Bluetti EB70 has a 716Wh / 700W battery that easily outperforms some mobile power stations. Part of this weight comes from using a LiFePO4 (lithium iron phosphate) battery, which is also used in electric vehicles.

While you can definitely connect a wide range of electronic devices, the battery actually has a limit to what you can connect to it.

Kettles, coffee machines or microwaves can work, but only if they do not exceed the maximum power. Anything around 800W or more will force the security system to step in and shut down the power station for security reasons.

Like most mobile power stations today, the EB70 offers three charging methods.

• • The most eco-friendly option is to charge via Bluetti’s own 200W solar panels.

• • You can also charge the power station using a car’s cigarette lighter.

• • Most people will likely charge the EB70 via the gargantuan 200W power adapter.

While the AC adapter method is the easiest and fastest charging option, fully charging in less than 4 hours, it is also the noisiest.

Unlike most portable power stations I’ve come across, the Bluetti EB70’s power supply has its own fan and it’s quite noisy.

Strangely, these fans turn on even if the EB70 isn’t charging as long as the charger itself is plugged in.

In other words, you have to unplug the charger when not in use, and it might annoy you one day.

Output power

The Bluetti EB70 has two sockets on the right side to meet all your needs and more. This is what differentiates a power station from a power bank.

On the opposite side is the DC group with a car charger, two DC barrel ports, two USB 3.0 ports and two 100W USB-C ports.

The top also features a 15W wireless charging pad – so it’s handy that the carrying handle can be folded out of the way.

What makes this particular Bluetti powerhouse stand out are those two USB-C ports. It not only supports the USB-C Power Delivery standard but also can output the maximum power of 100W.

And that’s not just a 100W split between the two outputs – it’s 100W each.

With all of these output options, the Bluetti EB70 can power almost any mid-range device, smartphone, tablet or MacBook Pro.

As with almost all power stations, the AC and DC output AC must be activated by pressing a button. This all works well, but the LED status is difficult to see in the sun.

The EB70 itself has fans to keep itself cool, and luckily they’re quiet during operation. However, they also start up when charging and can be a noisy affair, especially when paired with the already noisy power supply.

The Bluetti Powerstation supports pass-through charging on both DC and AC connections, so you can charge the power station and electronic devices at the same time.

For AC, Bluetti again boasts its pure sine wave inverter for maximum efficiency. The system works as advertised and is capable of dishing out that 700W of power.

The Bluetti SP200 solar panel

Of course, the power station is only part of the setup in the test, the other part is the SP200 solar panel.

The Bluetti PV200 solar panel consists of four panels that fold into a neat package. Some solar panels use a magnetic latch to lock everything shut…not so with the SP200 solar panel, which has two snap latches.

Once the solar panel is set up, the cables can be removed from the zipped pocket on the back and then plugged into the front of the Bluetti EB70.

On a sunny day, I found that I could charge an almost completely drained Bluetti EB70 to 100% in six to eight hours.

On a cloudy day, it takes about a day and a half to two days to fully charge a dead battery. Unfortunately, only 10 to 20 watts arrive, which is completely normal and other solar panels in this size range can’t do more.

On the back of the panel are 3 legs attached with Velcro that can be folded down. The great thing is that I can adjust the legs and align them exactly the same with the snaps.

Unfortunately, there are no hanging loops to hang the solar panel on a caravan, van or balcony. For that, you have to make something yourself.

The solar collectors are highly efficient and the monocrystalline solar cells have an efficiency of up to 23.4%.

I think the power of 200 watts is awesome and I like the power that is sucked out of the sun and delivered to my EB70 solar station.

Unfortunately, this is at the expense of the weight and at 7.3 kg you carry a few kilos with you – but in comparison, they are completely ok.

You can buy this great portable Power Station on Amazon, right here!

In comparison: The Jackery Solarsaga 100 watt solar panel weighs 4.68 kg.

Here are some technical data for the Bluetti PV200 solar panel:

• • Power: 200 watts

• • Lamination: ETFE (ethylene tetrafluoroethylene)

• • Cell Type: Monocrystalline Silicon

• • Cell efficiency: up to 23.4%

• • Item dimensions L x W x H: 63 x 59 x 10 cm

• • Weight: 7.3 kilograms

• • Connection: Standard MC4 connector

• • Cable Length: 3m

Questions and Answers

Can I also use two Bluetti 120 W solar panels to charge the Bluetti EB70?

You can also use two Bluetti 120 W solar panels, but the device only consumes a maximum of 200 W and not the expected 240 W.

I have a 50 watt device. How long can I then use it with a fully charged EB70 power station?

You can then use your device for about 12 hours. The calculation is as follows: 716 Wh * 0.85 / 50 watts = 12 hours.

Can the solar panel remain connected at night and does the EB70 power station continue to charge itself when the sun is shining?

The charge controller of the EB70 starts charging automatically, even after a long break.

Is it possible to connect the Bluetti EB70 to the solar panel and to the mains at the same time for faster charging?

The EB70 supports only one way of charging, while the Bluetti EB70S supports two-way charging at the same time.

Does the Bluetti EB70 power station switch itself off when no consumer is active?

When Eco mode is active, the AC output will turn off after 4 hours if the applied load is less than 10 watts. According to the description, everything on the DC side should remain on.

Which solar panels can I still connect to the Bluetti EB70 power station?

All solar modules that have between 12 V – 28 V and up to 200 W.

Where is Bluetti made?

Bluetti has its power stations and solar panels produced in China.

Bluetti EB70 test: My verdict on the EB70 Power Station

The Bluetti EB70 is a well-designed mid-pitch portable power station.

Although the capacity is in the middle range of the power stations of this type, the small additional power that you get compared to the EcoFlow River, for example, is fully sufficient.

Even with the more powerful Jackery Explorer 1000, I found the smaller and lighter weight of the Bluetti EB70 makes it easier to transport, especially if you have to carry it a few times.

There are several things I really like about the Bluetti EB70:

• • First, the simple design is a box with sockets on the front, including the power input. This positioning of the power in and power out allows you to easily connect devices so they don’t get in each other’s way or cover the power buttons.

• • Second, the wireless charging pad on the Bluetti EB70 is also great and one of those essential extras that I didn’t know I needed until I discovered it.

What is somewhat awkwardly constructed: the fan of the power supply always runs as soon as it is connected to the power supply (with 52 DB). This also means that the PSU fan spins even when the Bluetti EB70 is charged – so maybe half the night.

I also really like the Bluetti solar panel SP200. It’s still a little fiddly to set up by folding down the three Velcro-attached legs – but the individual panels are relatively light and slim, making them easy to carry.

I think the 200 watts from the SP200 solar panel are awesome, but unfortunately, there are no USB-A or USB-C connections, as is the case with the solar panels from Jackery or Anker.

The panels continue to be perfectly thought out, with the well-arranged location of the cables and the neat folding of the sections, all of which can be collapsed for transport or storage.

And if you are looking for something smaller, then check out the solar generator with the Bluetti PowerOak EB55 with 537 Wh.
