Are you a person who likes to go camping or travel to remote places where access to electricity is difficult, but at the same time want to be able to use all kinds of devices and “gadgets”? If so, the article we will be discussing along the following lines may be very interesting to you.
He Bluetti PowerOak EB70 It is a portable battery with which you can load all kinds of devices and even use tools such as drills, radials or appliances such as microwaves, coffee makers, sandwich makers, etc.… that you probably never imagined using away from a plug.
And is that the Bluetti PowerOak EB70 is much more than the typical power bank and not only for the capacity of its battery, but also for the number of electrical outputs it offers and the different charging possibilities it has. In addition as well it is possible to load it in different ways, both with the usual methods and with less common ones but with which you can get extra mobility that will allow you, if you want, to be away from a traditional electrical outlet for much longer.
Exterior of the PowerOAK EB70
The outside of the PowerOAK EB70 stands out for its dark blue or gray plastic case. It feels firm, thick and with rounded finishes. At both sides of the battery, the housing is dark gray and has a grille to facilitate ventilation of the internal components; something very necessary considering the temperature that the batteries can reach during their use; both at the time of loading and at the time of offer power to any connected device.
At the top it has a large folding handle that allows you to carry the battery comfortably. When the handle is folded it is integrated in the housing of the device, so you get a completely smooth surface at the top; perfect to be able to use the Qi charger (wireless charger) that it offers at the top and that It is ideal for charging mobile phones, powerbanks or other devices compatible with this technology and provides power of up to 15W at 5V / 3A.
On the front is where we find all the power inputs and outputs of the battery, as well as the few buttons, displays and other options that the battery has and which we will talk about in the following sections.
In terms of weight, the device reaches 9.7 kg, which is completely logical if we take into account the large capacity of the batteries included inside the housing.
Capacity, power and technology
Undoubtedly this is one of the most important sections of this product, as it depends on the number and type of devices it is capable of feeding.
The built-in battery inside the Bluetti PowerOAK EB70 is based on LiFePO4 technologythat is, based on Lithium-Ferrous, a variant of the most widely used technology today for small batteries that is Lithium-ion. He has one capacity of 716 Wh and a rated power of 1000 W.
This technology offers more stability when providing power and also its degradation is less, so the life of the battery will be longer than if the manufacturer had opted for another technology. Specifically, Bluetti claims that the PowerOK EB70 it will maintain up to 80% of its capacity after 2500 charge cycles.
Connection panel
As mentioned in the battery design section, on the front we find all the connections (with the exception of the wireless charger at the top) and this is where you can see the enormous possibilities of this type of product in different situations.
The first connector we find is that of charging the battery itself. It is in this connector where you must plug in the wall charger included with the device or use one of the alternative systems that I will talk about later and that are certainly more than interesting for everyone you want. stay away from a plug for a long time.
Right next to this charging connector is a small screen that shows information about the battery. Specifically shows at all times the percentage of remaining battery charge, the output frequency (50 Hz in the case of the European version which is the one we were able to test) and also the output or input power you are receiving at any given time. More than enough information to know what is happening at any given time.
The next thing we find is a flashlight. A small LED light with an on / off switch that can be very useful to illuminate around the device and thus more easily access the different connectors or just make it look more to avoid any bumps or tripping over it.
The next row is where we find all the available outputs. The first thing we find is a switch that allows you to turn off / on the power output of the first group of connectors, all of them direct current. In this section we find the following connectors:
- 2x USB-C 3.2: with an output of up to 100W perfect for charging portable and mobile devices, tablets, smart watches, laptops, etc, etc …
- 2x USB-A: with a maximum power of 15W at 5V / 3A.
- 2x DC5521: They provide an output of up to 120W at 12V / 10A, perfect for connect tools such as drills, drills or the like. Perhaps a port with a lesser known name, but widely used in everyday life by millions of people.
- 12V lighter: another socket capable of delivering up to 120W at 12V / 10A and that is capable of providing power to any device that uses this type of connector that is usually connected in cars and other vehicles.
Just below these connectors we find another area where we will find the AC outlets and as in the DC ones have a switch that allows you to turn them on or off. In this section we will see the following shots:
- 2x Schuko (Type F): is the most widely used type of plug in Europe, the typical round plug with two round plugs also 4.8 mm in diameter. These shots offer AC output at 220-240V and 50Hz and are capable of supplying up to 1000W rated power individually or jointly.
As you can imagine, in these connectors it is possible to plug in any device that does not exceed that power. That is, it is possible use it to power TVs, microwaves, toasters, coffee makers, and any other appliances, tool or device you may need.
Loading time and options
As discussed above PowerOAK EB70 includes a wall charger with which it is possible to charge the entire battery in about 3-4 hours thanks to the maximum capacity of 200W at which it is able to charge, but this is not the only option to charge the battery and this is where the thing is makes it very interesting.
The manufacturer himself offers two solar panel kits with which it is possible to charge the battery completely autonomously. We have not had the opportunity to test them, but according to the manufacturer in ideal conditions are able to charge the battery in 5-6 hours with the SP200 kit that offers up to 200W and in 7-8 hours with the SP120 that offers up to 120W. In case of less suitable situations such as shady areas or cloudy days, loading will be slower but it will also be possible to load it.
The last option to load is to use a charger with lighter connector. With this system the charging time will be about 7-8 hours due to the lower power supplied by plugs of this type, but it is certainly appreciated that the option is available for mobile loads. A note, it is recommended to use this method with the vehicle in which it is being charged, otherwise the battery may suffer too much and even run out completely.
Price and availability
Both the PowerOAK EB70 and solar panels can now be purchased on the manufacturer’s own website. The price of the battery is 749 €, although on the website they offer a discount of 50 € with the code BLUETTIEB70.
In addition, if you choose to purchase a pack with 120W solar panels the final price is € 999, which means a saving of € 109 compared to buying both devices separately.
This is definitely a product for a niche of very specific users. People in need always have a power source available even if they are in remote locations or also for professionals who need power for tools in places where it is not available, such as houses or other buildings under construction or renovation, and who cannot or need to have a fossil fuel generator.
