Frequently Asked Questions: AJ44 Power Bank with Type-C Cable and USB-A

1. What specifications are confirmed for the AJ44?

The AJ44 specification lists 10000mAh, 38.5Wh at 3.85V, a body size of 101.6 × 63.5 × 26.5mm, a weight of 210g, and PV+ABS material. Type-C input supports 5V/2.5A, 9V/2A, and 12V/1.5A. Type-C port and built-in Type-C cable output support 5V/3A, 9V/2.22A, and 12V/1.67A. USB-A output supports 5V/3A, 9V/2A, 10V/2.25A, and 12V/1.5A. Total output is listed at 22.5W maximum.

2. How is the AJ44 22.5W total output shared across its ports?

The specification confirms a 22.5W maximum total output but does not publish a verified per-port allocation table for simultaneous use. Buyers requiring multi-device charging should confirm the supported output combinations, shared-power limits, charging sequence, protocol behavior, overload protection, and temperature-rise results on the current PCBA. Individual port maximum ratings should not be added together or treated as guaranteed simultaneous output.

3. Which fast-charging protocols and devices are compatible with the AJ44?

The published table confirms voltage and current profiles for the Type-C port, built-in Type-C cable, and USB-A port. These electrical profiles alone do not prove support for every named protocol, phone model, or charging time. Buyers should verify protocol negotiation, actual power, device-specific behavior, and temperature rise using the intended phones and accessories during sample approval. Any QC, AFC, Apple, BC, or PD claim should match the current PCBA test report.

4. What are the confirmed size, weight, and material of the AJ44?

The AJ44 is listed at 101.6 × 63.5 × 26.5mm, 210g, and PV+ABS material. Pocket fit, grip, scratch resistance, and thermal behavior depend on the final housing finish, tolerance, user clothing or bag, cell, PCBA, and operating conditions. Buyers should confirm the material grade, color tolerance, surface-finish test, drop-test method, and temperature-rise results for the approved production sample.

5. Can the built-in Type-C cable recharge the AJ44 itself?

The current specification lists the built-in Type-C cable only under output, while power-bank input is listed separately for the Type-C input port at 5V/2.5A, 9V/2A, and 12V/1.5A. Buyers should therefore use the specified Type-C input port unless bidirectional cable input is explicitly confirmed for the current PCBA. If cable input is required, request a sample test, updated datasheet, and labeling that identify the supported input path and profiles.

6. How long does it take to recharge the AJ44?

A fixed recharge time is not confirmed by the published specification. Actual time depends on the Type-C input profile negotiated with the charger, cable condition, cell-capacity tolerance, temperature, PCBA settings, and starting state of charge. Buyers should request a recharge curve and test report for the production sample and intended charger instead of relying on an unconditional 2.5-hour or 4-hour claim.

7. What OEM and ODM options are available for the AJ44?

Standard OEM service starts at 500 pieces for logo and packaging on the existing AJ44 platform. Light customization, such as an approved shell color, documentation, or packaging change, generally starts at 1,000 pieces. Cable, battery, PCBA, firmware, connector, or structural changes are deeper ODM work and generally start at 2,000 pieces. Final MOQ, print method, color and cable feasibility, samples, tooling, lead time, and certification scope must be confirmed in the quotation.
