Description
AJ28 is a compact magnetic wireless power bank platform with a built-in Type-C cable, a separate Type-C port, a top digital display, and a square housing. The published table lists 10000mAh, two 105555 batteries, 75 × 64 × 25mm dimensions, and wired Type-C output profiles up to 12V/1.67A.

These are published model figures, not a substitute for the buyer-approved datasheet. Capacity, battery configuration, dimensions, weight, usable energy, wireless behavior, protocols, and test conditions must be confirmed before mass production or compliance use.
Magnetic Wireless Charging Verification
The product includes a magnetic wireless charging surface, but the current specification does not publish a verified wireless wattage range, supported profile matrix, controller or coil specification, magnet grade, holding force, alignment tolerance, case-thickness limit, or device-compatibility list. Buyers should request alignment and retention tests, temperature-rise data, foreign-object and abnormal-operation protection results, and tests using the exact target phones and cases.
Built-in Type-C Cable and Wired Output Profiles
The built-in cable and separate Type-C port list the same output profiles: 5V/3A, 9V/2.22A, and 12V/1.67A. The Type-C input lists 5V/3A and 9V/2A. These voltage/current combinations do not by themselves prove a named charging protocol, fixed device-specific speed, cable durability, or total output when multiple charging methods are used together. Request protocol negotiation records, cable-loss data, connector tests, simultaneous-output rules, and thermal results for the approved configuration.
Digital Display, Dimensions, Weight, and Color Approval
The top display is intended to provide a visible charging-status readout. Buyers should confirm exactly what it displays, value accuracy, refresh behavior, brightness, standby logic, firmware version, and any customization scope. Product artwork shows black-green, white-orange, light-green, and beige concepts, but available colors and color standards require written approval. The listed 75 × 64 × 25mm dimensions and 40g weight should be checked against a measured production-intent sample before they appear in packaging, listings, or compliance documents.
OEM and ODM Quantity Tiers
- 500 pieces: standard OEM logo and packaging on the existing AJ28 platform.
- 1000 pieces: project review for approved housing color, cable finish, documentation, display presentation, or packaging changes.
- 2000 pieces: deeper ODM review involving the battery, PCBA, firmware, wireless controller, magnet or coil layout, display system, cable, connector system, thermal design, dimensions, or enclosure.
Final MOQ, scope, samples, tooling, pricing, lead time, labeling, compatibility, certification, warranty, and inspection criteria must be confirmed in the quotation and approved production specification.
B2B Buyer Verification Checklist
- Confirm cell manufacturer, battery configuration, nominal voltage and watt-hours, usable-energy method, conversion efficiency, and lot-level capacity controls.
- Measure final dimensions and weight on an approved production-intent sample.
- Request the wireless profile matrix, controller and coil specification, alignment, retention, case, temperature, and protection test results.
- Verify Type-C protocols, port and cable output under required loads, shared-power behavior, cable durability, connector retention, and thermal limits.
- Approve display behavior, firmware, colors, logo, packaging, labels, manuals, compliance scope, warranty, and inspection criteria in writing.

Frequently Asked Questions: AJ28 Magnetic Wireless Power Bank with Digital Display
1. What specifications are currently published for the AJ28?
The current AJ28 table lists 10000mAh capacity, two 105555 batteries, dimensions of 75 × 64 × 25mm, weight of 40g, Type-C input profiles of 5V/3A and 9V/2A, Type-C port and built-in cable output profiles up to 12V/1.67A, and a magnetic wireless surface with a digital display. The table does not state a wireless output range, protocol certification, magnet grade, or display accuracy. Final figures must be confirmed on the approved production specification and sample.
2. How should buyers verify the AJ28 capacity, battery, size, and weight figures?
The combination of 10000mAh, two 105555 batteries, the published dimensions, and 40g weight requires technical verification before it is used in marketing or compliance documents. Buyers should request the cell manufacturer and model, cell datasheets, battery configuration, nominal voltage and watt-hours, measured sample dimensions and weight, charge and discharge energy curves, conversion-efficiency data, and lot-level capacity inspection records.
3. What should buyers verify about AJ28 wireless charging performance?
The current table identifies a magnetic wireless surface but does not publish wireless wattage, supported profiles, controller model, protocol certification, coil specification, or device test results. Buyers should request the wireless controller and coil specification, supported profile matrix, alignment and temperature-rise tests, foreign-object and abnormal-operation protection data, case-thickness limits, and tests using the exact target phones and cases.
4. What digital-display evidence should AJ28 buyers request?
The current specification does not define what the display shows, its resolution, update interval, accuracy, calibration method, low-battery behavior, or whether display content can be changed. Buyers should request the display and controller specification, firmware behavior, accuracy and repeatability tests, battery-state calculation method, sample video, and final approved user-interface and labeling requirements.
5. What simultaneous-output and thermal behavior should buyers verify?
The individual Type-C profiles do not establish the power available when wireless charging, the Type-C port, and the built-in cable are used together. The page does not publish a simultaneous-output matrix, shared-power limit, port priority, thermal architecture, or protection thresholds. Buyers should request controller data, temperature-rise and abnormal-operation tests, power-allocation logic, aging procedures, and tests for every required output combination.
6. What magnetic alignment and case-compatibility evidence should buyers request?
The current table does not publish magnet grade, magnet count, holding force, alignment tolerance, coil position, retention test, or case-thickness limit. Buyers should request the magnet and coil drawings, measured pull-force method and results, alignment and temperature tests, case-compatibility samples, and retention tests under the intended use conditions before publishing magnetic strength, security, or device-compatibility claims.
7. What OEM and ODM options are available for the AJ28?
Standard OEM service starts at 500 pieces for logo and packaging on the existing AJ28 platform. Light customization, such as an approved housing color, cable finish, documentation, display presentation, or packaging change, generally starts at 1,000 pieces. Changes to the battery, PCBA, firmware, wireless controller, magnet or coil layout, display system, cable or connector system, thermal design, dimensions, or enclosure are deeper ODM work and generally start at 2,000 pieces. Final MOQ, samples, colors, tooling, lead time, compatibility, labeling, and certification scope must be confirmed in the quotation.
