Description
AJ03 is a compact 10000mAh multi-output wireless power bank platform for OEM and ODM sourcing projects. The published specification defines its battery, dimensions, Type-C input and output profiles, and three wireless output levels; compatibility and simultaneous-use behaviour should be confirmed on the approved sample.

Type-C Input and Output Profiles
The published Type-C input profiles reach an 18W maximum, while the output profiles reach a 20W maximum. A connected device, cable and supported charging profile determine actual power. Protocol names and device-specific charging speeds are not established by the voltage table alone and should be verified using the final sample.
Three Wireless Output Areas
The specification lists a primary wireless output at 7.5W / 15W maximum and auxiliary wireless outputs at 5W and 3W. Buyers should confirm coil positions, supported output combinations, wired-plus-wireless power allocation, alignment tolerance, temperature rise, foreign-object response and target-device compatibility before publishing application claims.
OEM/ODM Quantity Tiers
- 500 pcs: quotation tier for the existing AJ03 platform with the approved OEM scope.
- 1000 pcs: quotation tier for projects requiring additional approved customization.
- 2000 pcs: quotation tier for deeper ODM evaluation.
Logo, housing colour, packaging, labels, wireless module, magnet system, battery, PCBA, firmware, samples, tooling, compliance scope, schedule and warranty must be confirmed in the written quotation. The quantity tier does not by itself guarantee that every customization item is available.
B2B Buyer Verification Checklist
- Confirm the final cell configuration, battery labels and usable output-energy test.
- Verify Type-C input and output profiles with the target charger, cable and devices.
- Test each wireless area and all required simultaneous-use combinations.
- Confirm coil and magnet layout, alignment tolerance and case-thickness limits.
- Review thermal data, protection behaviour and applicable wireless evidence.
- Verify battery, transport, electrical-safety, EMC and material documentation required for the target market.
- Approve logo, colour, packaging, labels and the 500 / 1000 / 2000 pcs quotation tier.

Frequently Asked Questions: AJ03 3-in-1 Wireless Power Bank 10000mAh
1. What specifications are confirmed for the AJ03?
The published AJ03 specification lists two 5000mAh cells, a total 38.5Wh rating at 3.85V, a 100 × 67 × 15mm body, 185g weight, ABS + PC material, Type-C input profiles up to 12V/1.5A with an 18W maximum, Type-C output profiles up to 12V/1.67A with a 20W maximum, a primary wireless output listed at 7.5W / 15W maximum, and auxiliary wireless outputs listed at 5W and 3W. Final cell configuration, labeling, wireless layout, and port behavior should be confirmed on the approved production datasheet.
2. What does 3-in-1 mean, and can the AJ03 outputs operate simultaneously?
The page lists one primary wireless output and two auxiliary wireless output levels, but it does not publish a verified simultaneous-output matrix, device-positioning diagram, total shared-power limit, priority logic, or wired-plus-wireless allocation. Buyers should confirm the supported output combinations, coil locations, target-device placement, total and per-output power, temperature rise, protection response, and whether any output is disabled or reduced when others are active.
3. What wireless compatibility evidence should AJ03 buyers request?
Published wattage levels do not by themselves prove a named wireless protocol, platform certification, universal device compatibility, magnetic alignment standard, or device-specific charging speed. Buyers should request the wireless module specification, applicable certification evidence, coil and magnet layout, alignment tolerance, foreign-object detection, case-thickness limits, efficiency and temperature-rise data, and test results for the exact target devices.
4. What should buyers verify for the AJ03 housing and magnetic attachment?
ABS + PC material is confirmed, but the material name alone does not prove a flame-retardant grade, impact rating, heat-dissipation advantage, yellowing resistance, scratch resistance, or long-term appearance. The page also does not publish magnet grade, holding force, case compatibility, or adhesion data. Buyers should request material declarations, flammability evidence where required, mechanical and cosmetic tests, pull-force and alignment results, and samples of the final enclosure and magnetic system.
5. How long does the AJ03 take to recharge, and how many device charges can it provide?
Verified full-recharge time, usable output energy, device charge counts, and cycle life are not published in the current specification. Results depend on the approved cells, charger and cable, negotiated input profile, conversion and wireless losses, temperature, battery age, output power, and target-device behavior. Buyers should request recharge curves, discharge-energy tests, cycle-test conditions, and device-charge tests with stated conditions before publishing runtime or charge-count claims.
6. What safety and compliance evidence should AJ03 buyers request?
Certification and audit claims must be verified for the exact model, battery, PCBA, wireless module, enclosure, and production configuration. Buyers should request applicable battery and transport documents, electrical-safety and EMC reports, wireless evidence, material declarations, quality-system and social-audit records where required, aging and inspection procedures, labeling files, report numbers, validity dates, and model traceability before using compliance claims in a target market.
7. What OEM and ODM options are available for the AJ03?
Standard OEM service starts at 500 pieces for logo and packaging on the existing AJ03 platform. Light customization, such as an approved shell color, documentation, or packaging change, generally starts at 1,000 pieces. Wireless module, magnet system, battery, PCBA, firmware, thermal design, connector system, or structural changes are deeper ODM work and generally start at 2,000 pieces. Final MOQ, color and packaging feasibility, samples, tooling, lead time, and certification scope must be confirmed in the quotation.
