Compatible lithium coin cells

This charger accepts lir2016, lir2025 and lir2032 lithium coin cells at 3.7V. It is intended for users who need to recharge these specific button batteries from a USB source. Ordinary non-rechargeable button cells must not be used, as doing so can damage the charger and cause the battery to explode.

USB-powered operation

The unit plugs into any standard USB port, laptop, power bank or vehicle USB socket for charging. It requires no separate mains adapter and draws power from the host device. The compact ABS housing measures approximately 78.3x23.62x14.33mm, making it easy to carry for travel or office use.

Steady 4.2V 1A output

Under sustained load the charger delivers a regulated 4.2V at 1A with a rated power of 2-5W. It operates from an AC input range of 110-240V at 50/60Hz through the connected USB source. The device has no intelligent charge management, quick-charge capability or display, so it provides a constant current without automatic termination.

Questions about this item

How many charge cycles can the 4.2V 1A output sustain before the 2-5W rate power drops off?

The charger delivers a steady 4.2V at 1A within a 2-5W power range, so sustained use stays inside those limits without a published cycle count.

Does the ABS housing stay cool and silent when the unit runs continuously from a 50/60Hz AC110-240V source?

With no fan or display and only 2-5W draw, the black ABS body remains cool and silent during all-day operation.

Which USB host — laptop port, power bank or car adapter — must I already own to power the 78.3×23.62×14.33mm charger?

Any standard USB-A port supplying 5V will power the charger; the package includes only the charger itself.
