A power platform with more roles.
Mobile-device charging
USB and Type-C outputs support compatible devices. Agree output profiles and cable requirements for the chosen electronics version; no unprovided fast-charge wattage is implied.
Charge indication & task light
The described configuration offers a percentage display, LED lighting and SOS mode. Housing references differ, so specify these features explicitly in the sample and order.
ABS housing & protection
The supplied specification lists thickened ABS and overload, overheating and overdischarge protection. It does not provide an IP rating, drop-test result or unconditional fire-resistance guarantee.
Choose the exterior with the configuration.
These references show different exterior designs, not opposite views of one pack. Select the housing and electronics together; the pictured indicator or port arrangement does not establish all described features.

Clear specifications. Fewer surprises.
Is a 2000 mAh cell the same as a 2000 mAh pack?
Not necessarily. Series connections increase voltage; parallel connections increase capacity. A 5S2P pack made with 2000 mAh cells has a calculated 4000 mAh capacity. Cell count and the series/parallel arrangement must be stated together. Delivered capacity is defined by the accepted pack specification.
Can every 18V–21V tool use the same pack?
No. Voltage labels alone do not establish compatibility. Check the slide geometry, contacts, polarity, electronics, current demand and charger for the exact model.
Does more Ah mean more torque?
Ah describes capacity, not a guaranteed increase in motor output or torque. Power delivery also depends on the cells, protection board, temperature, connectors and the tool.
Are the pictures production-label approvals?
The custom pack images are GEAKITA branding visualisations based on supplied product references. Housing variants, ports, displays, capacity labels and packing artwork are approved for the selected configuration before production.
