Description
AJ42 combines a 10000mAh battery, an integrated AC input and an attached Type-C cable in one power bank platform. The published table lists Type-C cable input and output profiles up to 20V/1.75A, with a stated 35W maximum for cable output. It separately lists AC charging mode at 110-240V~50/60Hz 0.3A maximum input and 5V/2A total output. These operating contexts should not be presented as the same output mode. Protocol support, pass-through behavior, seamless switching, regional plug compliance, laptop compatibility, thermal controls and final material data require confirmation on the approved production specification and sample.

These are published model figures, not a substitute for the buyer-approved datasheet, safety file or protocol evidence. Confirm cell configuration, rated capacity, usable energy, cable profiles, AC-mode behavior, material grade, plug construction, dimensions, weight, test conditions and final labels before quotation, mass production or compliance use.
35W Cable Mode and 5V/2A AC Mode Are Separate
The attached Type-C cable output table reaches 20V/1.75A with a stated 35W maximum. The AC charging row separately states total output of 5V/2A. Buyers should not describe the AJ42 as providing 35W wall-charger output unless a supplier-approved operating matrix and test report explicitly confirm that mode. Request a diagram showing power flow for battery operation, AC-connected operation, battery recharge and any combined-load condition, with measured input, output, allocation and temperature data.
Type-C Profiles, Protocols and Device Testing
The listed 20V/1.75A profile does not by itself prove PD, PD 3.1, EPR, laptop support, universal USB-C compatibility or a specific charging speed. Buyers should request the controller specification, protocol analyzer logs, source and sink matrices, supported voltage-current combinations, cable e-marker information where applicable, charger and device test records, voltage stability, ripple, protection thresholds and thermal results. Device names should be published only after testing the exact production configuration.
AC Input, Pass-Through and Regional Safety Verification
The integrated AC input is published as 110-240V~50/60Hz 0.3A maximum, but the table does not establish pass-through charging, uninterrupted switching, UPS behavior, output priority, regional plug variants or certification for every target market. Buyers should request the AC module and plug drawings, insulation and creepage design, input protection data, abnormal-operation tests, dielectric and leakage results where required, regional safety evidence, a verified pass-through matrix and clear instructions for wall-connected use.
Capacity, Material, Thermal and Physical Evidence
The page lists 10000mAh, 38.5Wh, 121 × 52.5 × 38mm, 273g and material described as PV+ABS. These figures do not prove usable output, a fixed number of device charges, pocket comfort, a specific polymer grade, flame rating, sensor design or a fixed temperature threshold. Buyers should request the cell datasheet, discharge and conversion-efficiency tests, measured production-intent samples, the exact material declaration, flammability evidence where required, temperature-rise data in battery and AC modes, thermal-throttling behavior, drop and vibration results, and lot-level inspection criteria.
OEM and ODM Quantity Tiers
- 500 pieces: standard OEM logo and packaging on the existing AJ42 platform.
- 1000 pieces: project review for an approved housing color, documentation, packaging, travel accessory or cable-finish change.
- 2000 pieces: deeper ODM review involving the battery, PCBA, firmware, AC module, plug system, cable, thermal design or enclosure.
Regional plug or mains-related changes require separate engineering and compliance review and should not be promised by MOQ alone. Final MOQ, feasibility, samples, tooling, pricing, lead time, protocol scope, market compliance, warranty, package contents and inspection criteria must be confirmed in the quotation and approved production specification.
B2B Buyer Verification Checklist
- Confirm battery capacity, 38.5Wh energy, usable-output method, conversion efficiency and lot-level cell controls.
- Separate battery cable mode from AC-connected mode in the approved power-flow and output matrix.
- Verify every Type-C profile and protocol claim with controller data, analyzer logs, charger tests and target-device tests.
- Request pass-through, switching, shared-output, protection and temperature results before publishing related claims.
- Approve the AC plug construction, insulation design, abnormal-operation evidence and target-market compliance scope.
- Confirm the exact material grade, dimensions, weight, cable durability, labels, manuals, accessories, warranty and inspection criteria.

Frequently Asked Questions: AJ42 AC Wall Charger Power Bank
1. What specifications are currently published for the AJ42?
The AJ42 table lists 10000mAh at 3.85V and 38.5Wh, a 121 × 52.5 × 38mm body, 273g weight, material described as PV+ABS, Type-C cable input and output profiles up to 20V/1.75A, cable output with a stated 35W maximum, and AC charging mode at 110-240V~50/60Hz 0.3A maximum input with 5V/2A total output. Final cell, material, protocol, AC-mode, plug and labeling details require confirmation on the approved production specification.
2. Is the AJ42 35W cable output the same as its AC charging-mode output?
No. The published table lists up to 35W for the attached Type-C cable output, while the separate AC charging row lists total output at 5V/2A. Buyers should request a verified operating matrix before describing wall-connected output, pass-through behavior or power allocation.
3. Does the listed 20V/1.75A profile prove PD or laptop support?
No. A voltage-current profile alone does not prove PD, PD 3.1, EPR, laptop compatibility or device-specific charging speed. Buyers should request controller data, protocol analyzer logs, cable information and tests using the exact target chargers and devices.
4. Can the AJ42 be described as a pass-through charger or UPS?
The current table does not establish simultaneous battery recharge and device output, seamless source switching, uninterrupted output, priority rules or UPS behavior. These claims require a supplier-approved power-flow diagram and measured tests for every required AC, battery and load condition.
5. How should buyers evaluate the AJ42 size and 273g weight?
The published size is 121 × 52.5 × 38mm and the listed weight is 273g, but these values do not establish pocket comfort or suitability for every travel use. Buyers should review measured production-intent samples, packed weight, cable storage, plug retention, drop and vibration results, and the target bag or accessory fit.
6. What material and thermal evidence should AJ42 buyers request?
PV+ABS is the published material description, but the page does not prove an exact polymer grade, flame rating, sensor layout, 45-degree limit, ventilation design or fixed thermal performance. Buyers should request the material declaration, flammability evidence where required, battery and AC-mode temperature-rise tests, protection thresholds, thermal-throttling behavior and abnormal-operation results.
7. What OEM and ODM options are available for the AJ42?
Standard logo and packaging on the existing AJ42 platform starts at 500 pieces. Approved housing, documentation, packaging, travel accessory or cable-finish projects require review from 1000 pieces. Battery, PCBA, firmware, AC module, plug system, cable, thermal design or enclosure changes generally require a 2000-piece ODM review. Regional mains changes also require separate engineering and compliance approval.
