OBAL: ME EnergyPulse 20000mAh 22.5W

External battery with a nominal capacity of 20,000 mAh (74 Wh). By staying below 100 Wh, it complies with IATA regulations, allowing it to be transported in the cabin of commercial aircraft without restrictions. The device uses lithium polymer (Li-Pol) cells, a chemistry that ensures greater voltage stability and extended life by reducing the memory effect.

22.5W fast charging

The fast charging system achieves a maximum power output of 22.5W. It has three output ports: two USB-A ports with variable voltages (5V, 9V and 12V) and a bi-directional USB-C port. Internal electronics manage power negotiation automatically, adjusting power to the specific requirements of each smartphone or tablet to minimise thermal stress and optimise speed.

Simultaneous charging of 3 devices

In this scenario, the controller activates a protection mode that limits the total output to 15W (5V/3A) spread across the active ports. This limitation prevents overheating of the motherboard and ensures the integrity of the internal cells during intensive use.

Self-charging via USB-C

To recharge the unit itself, the bi-directional USB-C port supports inputs of up to 18W. With a compatible 20W wall charger, the battery completes its charge cycle in approximately 6 hours. The time increases significantly (over 15 hours) if a standard 5W adapter is used. It also includes a 10.5W MicroUSB input for backwards compatibility.

Dimensions and safety

The chassis, made of retardant materials, measures 141.5 x 67 x 27.5 mm and weighs 410 grams. A digital LED display on the front panel shows the exact percentage of charge remaining (0-100%). Safety is completed by overvoltage (OVP), overcurrent (OCP), short-circuit (SCP) and temperature (OTP) protection modules.
