go-e Charger Gemini 2.0: Rated GOOD (1.5) - in Auto Bild and P3 Wallbox Test

Recently, the technology consultancy P3, in collaboration with the publishing partner Auto Bild, conducted a comprehensive test of eight intelligent wallboxes designed for home use. Various aspects were evaluated, including functions that go beyond the pure battery charging function.

The go-e Charger Gemini 2.0 made it into the top three of the wallboxes tested, with the test result GOOD an overall score of 1.5 and a price-performance score of 1.2 (VERY GOOD). Our product impressed with its SIM card, which enables communication independently of a sufficient WiFi connection. The appealing design of the app also stood out, which makes us particularly pleased that we have launched a new, improved version of the app this year.

In the test, P3 and AUTO BILD evaluated eight popular wallboxes, assessing their installation, charging process, smart charging features, and overall operation. The models tested included: 

• ELLI CHARGER PRO 2

• KEBA | KECONTACT P40

• go-e Charger Gemini 2.0

• ZAPTEC GO

• HEIDELBERG CONNECT-SOLAR

• MENNEKES AMTRON 4YOU 510

• KOSTAL ENECTOR

• WALLBOX ABL PULSAR

The experts examined various aspects such as assembly and installation, charging performance, smart features, standby consumption, and more. Based on the installer ratings, consumer feedback, and price-performance ratio, the wallboxes received grades ranging from 1.4 to 2.6.

• Elli Charger Pro 2 – Rated 1.4, this wallbox offers solid PV integration and price-optimised charging. It provides a range of app-based features and includes support for the EEBUS interface as well as LTE via eSIM.

• Zaptec Go 22 kW 4G – In second place, this wallbox features a 5-year warranty, built-in LTE with eSIM, and the option for dynamic charging control through external services.

• go-e Charger Gemini 2.0 – Our wallbox claimed third place with a score of 1.5, recognised for its straightforward and well-thought-out installation, reliable communication even without strong WiFi, and user-friendly app design.

Among other things, P3 and Auto Bild highlighted the easy integration of the wallbox with the in-house go-e Controller and its compatibility with third-party energy management systems. The advanced functionalities of the go-e Charger, such as PV surplus charging and dynamic electricity tariffs, were given recognition. The installation was praised for its simplicity, as it requires minimal wiring without the need to even open the wallbox.

P3 conducted its tests in a specialised laboratory in Osnabrück. Wallboxes with alternating current (AC) technology designed for home use were examined. During the process, 115 criteria were used for evaluation. The experts considered the perspectives of both installers and end-users.

The test began with unboxing. At this stage, the focus was on packaging quality. P3 also examined the interior layout of the wallboxes. When it came to the setup, the clarity of operating instructions was analysed. They checked for cable routing space and potential installation challenges. These aspects helped grade the devices based on how easy they were to handle for electricians.

P3 tested the wallboxes with a simulator to assess communication with electric vehicles. Additionally, they performed real-world trials with the Mini Cooper SE and BMW iX3. The experts analysed the charging process for interruptions, measured standby energy consumption, and checked the wallboxes for safety features like overvoltage protection.

P3 tested the app to make sure the smart features are easy to use. This included checking Wi-Fi and RFID connections, remote control, access to charging data, and cyber security. They also tested features like compatibility with energy management systems and dynamic tariffs to ensure the device is up-to-date.
