Battery competence.

That convinces. Again and again.

We are battery test winners

At Stiftung Warentest

The test victory goes to: Einhell! In a current comparison test by Stiftung Warentest, a German consumer organsation, with eight batteries from eight different battery platforms, the 2.0 Ah battery from Einhell's Power X-Change battery system came out on top against strong competition. Our battery convinced in terms of durability, handling and safety. After having already achieved top marks in previous tests with Power X-Change devices by Stiftung Warentest, we are now all the more pleased that our batteries, whose development we attach great importance to, have won the test.

We are incredibly proud that we were able to hold our own in the race with top-class competitors and clearly demonstrate our battery expertise. We are battery test winners.

These categories have been tested


Tested components for reliable durability

High-performance cells in combination with intelligent battery management ensure efficiency, reliability and durability in our Power X-Change batteries. The components are continuously subjected to strict quality tests. As a partner of BMW i Motorsport in Formula E, our batteries have to meet the high demands of the racing garage. In the test, all batteries had to survive 400 charging cycles to prove their durability. Our battery was convincing and received the grade 2.1.


Pleasant handling, easy charging

The shock- and dust-proof plastic cover of our battery pack not only protects its inner life, but also increases the user-friendliness of the battery with the practical recessed grip for insertion and the easy-to-see charge level indicator. The charging time was also rated as good, achieving a grade of 2.0 in the handling area.


Top marks for safety

Our in-house processor-controlled battery electronics, the Active Battery Management System, is specifically designed for long battery life and safety. It monitors all safety-relevant influences inside each Power X-Change battery and controls the optimal use of the individual cells. This paid off in the test conducted by Stiftung Warentest, the German consumer watchdog, as we received the top score of 1.0 for safety.

Power consumption of charger

Cell-saving charging made easy

The higher the charge current, the higher the power consumption, of course. A higher charging current also shortens the charging time, but since batteries age faster, the use of such chargers is only recommended in exceptional cases. Our 3 A standard chargers, as tested, on the other hand, are ideal for standard applications. For this, Stiftung Warentest gave it a grade of 1.6. If it has to go faster, the fast charging function of our 6 A Boost Charger can be switched on by pressing a button if necessary. This saves the battery and increases the service life.

Technical features

Compatibility - even outside of the Einhell system

In addition to the test categories, other features of the battery platforms were also compared in the test, e.g. the different applications of the batteries and their compatibility. Here our Power X-Change battery could convince across the board. Our platform batteries are compatible with all 250 Power X-Change devices. Power X-Change is the first system that offers such a wide range of products for do-it-yourselfers and hobby gardeners alike. And thanks to Einhell's Twin Pack technology, 36V appliances are also part of the platform. Here 2 batteries are simply combined. Besides Einhell tools, third party devices can also be operated with our batteries, e.g. the Elmoto e-kick scooter from GOVECS.

From test winners and top marks

Our devices

Power X‐Change devices have already received top marks twice from Stiftung Warentest. But other test magazines also regularly subject Einhell tools and gardening equipment to a strict examination.
