How to choose the right accessory

Capacity, watt-hours and real usable energy

A bank’s mAh rating is normally measured at its internal cells, not at a phone’s charging voltage. Conversion and heat consume some energy, so the actual number of phone recharges will be less than dividing the printed capacity by the phone battery size. Watt-hours offer a better measure for comparing very different bank sizes; they are also relevant for airline rules. A heavier unit may be worthwhile on long journeys but less pleasant for daily commuting.

Power delivery and cables

A 20,000mAh battery is not necessarily faster than a 10,000mAh battery. Charging speed depends on the maximum wattage of each port, USB Power Delivery or other protocol support, the input limit on your device and the cable in between. USB-C connectors are common but not universal proof that laptop charging will work. Verify your device’s minimum recommended wattage.

Heat, travel and battery safety

Use undamaged cables, avoid exposing lithium batteries to excessive heat or crushing, and stop using a bank if it swells. Airline allowances for spare lithium batteries are measured in Wh rather than simply mAh, and larger banks such as 148Wh or 185Wh may fall outside ordinary passenger allowances. Always confirm the airline’s current rules before travelling.

How to choose the right size

The lightest suitable power bank tends to be the most convenient. For short commutes, prioritise a pocket option; for phones and tablets across a long working day, consider 20K capacity; for higher-power devices, start by checking required USB-C output. Buying maximum capacity without a use case increases carrying weight rather than automatically improving value.

Before ordering from Infinite Tech

Match the device and its exact model to the intended function; read the included documentation and inspect the retailer’s stock status and final price. Popularity-sorted marketplace pages can provide an indication of products being promoted or reviewed but are not proof of the sales totals at Infinite Tech. Review the product colour, plug or connector, accessories in the box and warranty terms before paying.
