These are published model figures, not a substitute for the buyer-approved datasheet or protocol evidence. Confirm cell configuration, usable energy, wireless implementation, Type-C protocol support, material grade, dimensions, weight, test conditions, and final labels before quotation, mass production, or compliance use.
Magnetic Wireless Charging Verification
The published wireless modes reach 15W, but this does not prove a fixed rate for every device, Qi or MagSafe certification, a particular magnet grade, universal magnetic compatibility, coil alignment, case compatibility, or performance under simultaneous loads. Buyers should request the wireless controller specification, supported profile matrix, magnet and coil drawings, pull-force and alignment tests, case-thickness limits, foreign-object and abnormal-operation protection data, temperature-rise results, and tests using the exact target phones and cases.
Type-C 20W Profile and Protocol Checks
The listed Type-C output profiles reach 12V/1.67A with a stated 20W maximum, while input is listed at 5V/2A and 9V/2A. These voltage/current profiles do not by themselves confirm PD certification, fixed recharge time, device-specific speed, support for laptops or tablets, or simultaneous wired and wireless behavior. Request controller data, protocol analyzer logs, source and sink matrices, charger/device tests, voltage stability, protection thresholds, and thermal results.
Simultaneous Output and Thermal Evidence
The current table lists wired and wireless outputs separately but does not publish a verified simultaneous-output matrix, total shared-power limit, output priority, or power-reduction behavior. The aluminum housing alone does not establish a specific surface temperature or cooling advantage for the complete product. Buyers should request combined-load tests, power-allocation logic, cell and PCBA temperature data, surface-temperature measurements, thermal throttling behavior, abnormal-operation tests, and aging conditions for the final configuration.
Aluminum Finish, Dimensions, and Display Approval
The published body size is 66 × 14.2 × 103.5mm, with Gunmetal and Titanium finish options and a front battery readout. One earlier artwork asset stated 10.35mm and has been removed from this page because it conflicts with the parameter table. Buyers should confirm dimensions and weight on a measured production-intent sample and request the alloy grade, electrical insulation design, surface-treatment process, color standard, adhesion, abrasion and scratch tests, display content and accuracy, finish sample, and production tolerances.
OEM and ODM Quantity Tiers
- 500 pieces: standard OEM logo and packaging on the existing AJ40 platform.
- 1000 pieces: project review for an approved finish, color, documentation, gift packaging, or accessory presentation.
- 2000 pieces: deeper ODM review involving the cell, PCBA, firmware, magnetic system, coil layout, display, thermal design, or structure.
Final MOQ, scope, samples, finish feasibility, tooling, pricing, lead time, compatibility, labeling, certification, warranty, package contents, and inspection criteria must be confirmed in the quotation and approved production specification.
B2B Buyer Verification Checklist
- Confirm cell specification, 38.5Wh rated energy, usable-energy method, conversion efficiency, transport records, and lot-level capacity controls.
- Request wireless profile, magnet, coil, alignment, pull-force, case, temperature, and protection test evidence.
- Verify Type-C profiles and any protocol claims with controller data, analyzer logs, charger/device tests, and shared-output rules.
- Approve alloy grade, insulation, surface process, finish, color, scratch resistance, dimensions, weight, display behavior, and thermal performance.
- Define logo, packaging, labels, manuals, accessories, compliance scope, warranty, and inspection criteria in writing.

Frequently Asked Questions: AJ40 Premium Aluminum Magnetic Power Bank
1. What specifications are currently published for the AJ40?
The AJ40 table lists 10000mAh at 3.85V and 38.5Wh, dimensions of 66 × 14.2 × 103.5mm, an aluminum-alloy housing, Type-C input at 5V/2A and 9V/2A, Type-C output profiles up to 12V/1.67A with a stated 20W maximum, wireless output modes of 5W, 7.5W, 10W, and 15W, and Gunmetal or Titanium colors. Final cell configuration, weight, protocols, tolerances, and labels require confirmation on the approved production specification.
2. How should buyers compare the AJ40 10000mAh capacity with other power banks?
Published battery capacity does not establish a fixed number of full phone charges. Usable output varies with nominal voltage, conversion efficiency, wireless transfer losses, cable condition, temperature, device battery size, and charging behavior. Buyers should compare rated watt-hours and request cell datasheets, discharge curves, wired and wireless usable-energy tests, conversion-efficiency data, cycle-aging conditions, and lot-level capacity inspection records.
3. What should buyers verify about AJ40 magnetic wireless charging?
The table lists 5W, 7.5W, 10W, and 15W wireless modes but does not prove Qi or MagSafe certification, a specific magnet grade, universal case compatibility, or full 15W output for every device. Buyers should request controller, coil and magnet specifications, supported profile matrices, alignment and pull-force tests, case-thickness limits, foreign-object and abnormal-operation protection data, temperature-rise results, and tests using the required phones and cases.
4. Can the AJ40 use wireless and Type-C outputs at the same time?
The current table lists wireless and Type-C outputs separately but does not publish a verified simultaneous-output matrix, total shared-power limit, port priority, or power-reduction behavior. Buyers should request tests for every required output combination, including total and per-output power, voltage stability, temperature rise, protection response, and whether either output is reduced or disabled under combined loads.
5. What does the published 20W Type-C output establish?
The listed Type-C profiles are 5V/3A, 9V/2.22A, and 12V/1.67A with a stated 20W maximum. These values do not by themselves prove PD certification, device-specific speed, laptop support, a fixed recharge time, or compatibility with every charger and cable. Buyers should request controller data, protocol analyzer logs, source and sink matrices, charger/device results, voltage stability, protection thresholds, and temperature data.
6. What aluminum finish and thermal evidence should AJ40 buyers request?
The table states aluminum alloy and Gunmetal or Titanium colors but does not publish the alloy grade, anodizing method, hardness, scratch rating, fingerprint performance, or a verified surface-temperature limit. Buyers should request the material and insulation specification, surface-treatment record, color standard, adhesion, abrasion and scratch tests, wired and wireless temperature-rise data, thermal-throttling behavior, and approved finish samples.
7. What OEM and ODM options are available for the AJ40?
Standard OEM logo and packaging on the existing platform starts at 500 pieces. Finish, color, documentation, gift packaging, or accessory-presentation projects require review from 1000 pieces. Cell, PCBA, firmware, magnetic system, coil layout, display, thermal design, or structural changes generally require a 2000-piece ODM review. Final MOQ, feasibility, samples, tooling, pricing, lead time, compliance scope, warranty, and inspection criteria must be confirmed in the quotation and approved specification.
