Specifications

Compatibility and Usage

Recharge the power bank using a suitable input source, then connect the device to an appropriate output with the correct cable or built-in connector. Check charge status before leaving home. A power bank’s input rating describes how it recharges; output ratings describe what it can supply to connected equipment.

The stated battery capacity is the internal cell capacity, not a guaranteed number of complete phone charges. Conversion losses and the phone’s own battery size affect usable charging. For higher-power equipment, compare the supported output profile with the device’s requirements instead of relying only on the capacity figure.

For everyday use, carry the appropriate cable if the device requires one and check that the connector seats fully through any fitted case. Put the bank and phone on a stable surface while charging. Avoid carrying either item by a cable or leaving a connector under continuous sideways pressure.

Frequently Asked Questions

Will it charge my device at the maximum output?

Only if the device, selected connection and cable support the relevant charging mode. Charging power changes with battery level and operating conditions, even when the equipment is compatible.

How should I choose an input charger?

Match the bank’s input connector and supported charging profile. A source with a higher rating does not make the bank accept more power than its input limit.

How many phone charges will it provide?

That depends on the phone battery, starting charge level and conversion losses. Use the capacity as a comparison point rather than treating it as a fixed recharge count.

What should I check before using a built-in or separate connector?

Make sure it matches the device socket and seats properly through any case. Keep the phone and bank supported, leaving space for the connection instead of using a cable or plug to hold their weight.
