With the E-Booster Digital Mini, Topeak has added a compact electric mini pump to its range that is set to set a new benchmark in terms of size. Despite its minimal size, the E-Booster is designed to create a maximum pressure of 8 bar, providing cyclists of all categories with comfortable support in the event of a flat tyre.

The Topeak E-Booster Digital Mini sets a new benchmark for electric pumps in terms of compactness. The Mini measures just 5.4 x 3.4 x 7.2 centimetres, making it 25 percent smaller than its predecessor. predecessor, the E-Booster Digital. It also marks a new top value in terms of weight: at just 120 grams, it is an impressive 42 grams lighter and therefore weighs even less on tour than the E-Booster Digital. With a capacity of 500 mAh, the 7.4-volt battery is 100 mAh less than its predecessor, but still manages the same maximum air pressure: 120 psi or 8 bar.

The TFT LCD display shows pressure values in three units: kg/cm², bar and psi. The backlight ensures readability in poor lighting conditions. The accuracy is 0.1 bar or 2 psi. The pre-selectable air pressure activates the auto-stop function, which automatically ends the pumping process.

SmartHead technology meets valve diversity

The SmartHead pump head fits Presta and Schrader valves, as well as the Topeak TurboFlow valve adapter (increases the air flow). The extension hose is designed to protect TPU hoses with plastic valve stems from overheating. The pumping speed varies considerably depending on tyre size and target pressure. To inflate a 2.4 inch wide mountain bike tyre to 1.7 bar, the E-Booster Digital Mini needs around 80 seconds.

The USB-C connection fully charges the battery in around 35 minutes. The Auto-OFF function switches the pump off automatically when not in use and conserves the battery. A torch function completes the equipment for night-time breakdowns. The supplied storage bag and waterproof zip bag complete the accessories.
