Type-C Input and Output Profiles
The listed Type-C input profiles reach 18W, while the output profiles reach 20W. Actual charging power depends on the approved PCBA, connected device, cable, negotiated profile, temperature and state of charge. Protocol names and device-specific charging times should be verified rather than inferred from wattage alone.
Magnetic Wireless Charging Configuration
The specification lists wireless output up to 15W, and the product media shows the AJ04 attached to a phone. Buyers should confirm magnet layout, holding force, coil alignment, supported wireless profiles, case-thickness limits, foreign-object response, temperature rise and device compatibility on the final sample. The wired and wireless maximum ratings should not be added together without a verified simultaneous-output matrix.
Capacity and Battery Configuration Note
The product title and current record identify AJ04 as a 5000mAh model, while the legacy table contains the notation “5000mAh*2/3.85V”. Because these entries may describe different battery configurations, the final cell count, nameplate capacity, rated energy in Wh, usable output energy and product label must be confirmed in the approved production datasheet before ordering or publishing capacity claims.
OEM/ODM Quantity Tiers
- 500 pcs: quotation tier for the existing AJ04 platform with the approved OEM scope.
- 1000 pcs: quotation tier for additional approved colour, packaging or documentation changes.
- 2000 pcs: quotation tier for deeper ODM evaluation involving hardware, battery, PCBA, firmware or structure.
Logo, colour, transparent housing finish, packaging, labels, accessories, samples, tooling, compliance scope, schedule and warranty must be confirmed in the written quotation. A quantity tier does not automatically guarantee that every customization item is available.
B2B Buyer Verification Checklist
- Resolve the 5000mAh versus “5000mAh*2” battery notation before approval.
- Verify Type-C input and output profiles with target chargers, cables and devices.
- Test wireless power, magnetic holding force, alignment and case compatibility.
- Confirm wired-plus-wireless simultaneous-use behaviour and total power allocation.
- Review temperature-rise, foreign-object and protection-response test data.
- Verify battery, transport, electrical-safety, EMC, wireless and material documents required for the target market.
- Approve logo, colour, packaging, labels and the 500 / 1000 / 2000 pcs quotation tier.

Frequently Asked Questions
1. What charging specifications are confirmed for the AJ04?
The published AJ04 specification lists Type-C input profiles of 5V/3A, 9V/2A, and 12V/1.5A; Type-C output profiles of 5V/3A, 9V/2.22A, and 12V/1.67A (up to 20W); and wireless output up to 15W. Actual charging power depends on the connected device, supported protocol, receiver alignment, temperature, and state of charge.
2. How long does the AJ04 take to recharge?
The listed Type-C input supports profiles up to 18W, but a fixed 0–100% recharge time cannot be confirmed from input wattage alone. Recharge time depends on the approved battery configuration, charger profile, charging curve, temperature, and conversion losses. Buyers should request a recharge test log made with the charger intended for their target market.
3. Can the AJ04 use wired and wireless output at the same time?
The AJ04 specification lists a Type-C output up to 20W and wireless output up to 15W. It does not, by itself, confirm the power available when both outputs are active, so the two maximum ratings should not be added together. Confirm simultaneous-output support, power allocation, protocol behavior, and temperature rise on the approved sample and current PCBA specification.
4. What are the confirmed capacity, size, and weight of the AJ04?
The current product record identifies the AJ04 as a 5000mAh magnetic wireless power bank with a body size of 70 × 65 × 16mm and a weight of 115g. Usable output energy is lower than the nameplate cell capacity because of voltage conversion and thermal management. For procurement, transport, and compliance documents, confirm the final battery configuration and rated energy in watt-hours (Wh) on the approved datasheet and product label.
5. Which phones and cases are compatible with the AJ04 magnetic wireless charging function?
The AJ04 provides wireless output up to 15W, but magnetic attachment and charging power depend on the phone’s receiver, magnetic alignment system, case thickness, case material, and thermal conditions. Non-magnetic phones or cases may require a compatible magnetic ring or case; whether that accessory is included must be confirmed in the quotation and approved packaging list.
6. What OEM and ODM options are available for the AJ04?
Standard OEM service starts at 500 pieces for logo and packaging on the existing AJ04 platform. Light customization, such as confirmed color or packaging changes, generally starts at 1,000 pieces. Hardware, PCBA, firmware, battery configuration, or structural changes are treated as deeper ODM work and generally start at 2,000 pieces. Final MOQ, lead time, colors, accessories, and tooling scope must be confirmed in the quotation.
7. What safety and compliance documents should buyers request for the AJ04?
The published housing material is ABS. Before placing a production order, buyers should request the model-specific battery specification, protection-circuit description, UN38.3 test summary, MSDS, and the CE, FCC, or RoHS reports required for the target market. Certificate model numbers, applicant names, report dates, and production configuration should match the approved AJ04 sample and order documents.
