Juice Booster 3 Air in Device Control: that’s what the world’s smallest charging station can do

With over 30 adapters available, the 3 Air can be connected to almost any power connection in the world, whether it’s a domestic household socket or a 400-volt industrial plug. So the 3 Air can be used both as a charging station at home and as a mobile charger on the go – for example, if no suitable charging option can be found outside of an ordinary outlet (also interesting: charging is a problem in these holiday countries). The device automatically sets the maximum possible charging power, detects faulty power connections in detail and turns itself off if it overheats – a roasted socket is not possible with the 3 Air.

No connection for external chargers

Compared to the still available Juice Booster 2, there is the specially developed “J+ Pilot” app for the 3 Air – this greatly increases the possible uses of the charging station: the app not only ensures that charging is done properly, it is controlled and monitored from the couch, but a At a glance, you can also see how much electrical energy is charged and how much.

In addition, the 3 Air can be blocked even for “external loaders”: For this purpose, two RFID cards are included in the scope of delivery, these cards must first be held against the Type 2 connector of the vehicle after registration in the application before the loading process actually starts with the integrated RFID reader. If the function is activated via the app (“Authorization by RFID”), only people with an RFID card can draw electricity from the charging station. This is practical, for example, in larger developments with a lot of potential “electricity thieves”.

Convenient load management

Another smart feature is the dynamic load management “SmartJuice”: Up to ten 3-Air charging stations can be connected to each other and communicate with each other via the cloud. Therefore, the charging stations can be used without hesitation in multi-party garages where no professional, often expensive, load management can be installed. If more than one vehicle is charging at the same time, the system dynamically distributes the maximum available charging power between the vehicles and ensures that the home connection is not overloaded to the specified limit value.

But the Juice Booster 3 Air can also be used like a regular type 2 charging cable, for example at public charging stations. And here comes the only weak point of the device: the maximum charging power of the 3 Air is only 11 kilowatts (kW) – with the 2 a maximum of 22 kW was still possible. The logic of Juice: Since the maximum power of the on-board AC charger in most electric cars available today is already only 11 kW, the power reduction also made it possible to significantly reduce the dimensions of the device and cables. So if you want to keep charging with 22 kW, you can continue to use the Juice Booster 2, which is twice as heavy as the new 3 Air with all its cables.

Quality has a price

And the high-tech “Made in Switzerland” lightness also has a price: depending on the store, the Juice Booster 3 Air in the “Swiss Basic Set”, which includes household and industrial charging plugs, costs between 1200 and 1550 francs. The handy Type 2 adapter for charging at public charging stations costs CHF 169. The cheaper but also significantly larger Juice Booster 2 starts at 1000 francs.
