AJ45 AC Plug Power Bank 20000mAh for OEM and ODM Projects
The AJ45 is a 20000mAh power bank platform with an integrated AC input, built-in Lightning and Type-C output cables, and a separate Type-C port. The published specification lists a 3.85V battery rating, a 107.5 × 58.6 × 48.3mm body, 380g weight, and ABS + PC housing.
The Type-C input supports profiles up to 12V/1.67A. The separate Type-C output is listed at up to 20W, while the built-in cable profiles are listed up to 12V/1.67A. AC input is specified as 220–240V / 50Hz. Buyers should confirm protocol support, shared-output behavior, plug design, recharge performance, target-market compliance, and final labeling on the approved sample and production datasheet.
OEM and ODM Order Guidance
- 500 pieces: standard OEM logo and packaging on the existing AJ45 platform.
- 1,000 pieces: light customization such as an approved housing color, documentation, packaging, or accessory change.
- 2,000 pieces: deeper ODM work involving the AC input system, plug structure, battery, PCBA, firmware, thermal design, built-in cable system, or enclosure.
Final MOQ, plug and voltage feasibility, samples, tooling, lead time, labeling, and certification scope must be confirmed in the quotation.
Frequently Asked Questions: AJ45 AC Plug Power Bank 20000mAh
1. What specifications are confirmed for the AJ45?
The published AJ45 specification lists 20000mAh at 3.85V, a 107.5 × 58.6 × 48.3mm body, 380g weight, ABS + PC material, Type-C input profiles up to 12V/1.67A, a separate Type-C output listed at up to 20W, AC input at 220–240V / 50Hz, and built-in Lightning and Type-C cable output profiles up to 12V/1.67A. Final cell configuration, usable energy, protocols, connector design, labeling, and output behavior should be confirmed on the approved production datasheet.
2. Can the AJ45 built-in cables and Type-C port operate simultaneously?
The page lists two built-in cable outputs and a separate Type-C output, but it does not publish a verified simultaneous-output matrix, total shared-power limit, power-allocation logic, or protocol behavior under multiple loads. Buyers should request test data for each required output combination, including total and per-port power, voltage stability, temperature rise, protection response, and whether any output is reduced or disabled when another output is active.
3. What should buyers confirm about the AJ45 AC input?
The published specification states 220–240V / 50Hz. It does not prove compatibility with 100–120V grids, 60Hz operation, every plug standard, or automatic worldwide voltage switching. Buyers should confirm the target country, mains voltage and frequency, plug geometry, insulation system, creepage and clearance, fuse and protection design, recharge performance, labeling, and applicable safety and EMC evidence before production.
4. What transport and airline evidence should buyers request for the AJ45?
A mathematical calculation from the published 20000mAh and 3.85V ratings gives 77Wh, but this calculation alone is not an airline approval or transport certificate. Buyers should verify the rated energy printed on the final product, battery configuration, transport test summary, shipping documents, packaging and labeling requirements, carrier and airline rules, and current requirements in every market and route. Power banks are generally subject to carry-on and handling restrictions that must be checked with the carrier.
5. What thermal and safety evidence should AJ45 buyers request?
ABS + PC material and the listed electrical profiles do not by themselves prove a specific flammability grade, continuous-temperature rating, internal temperature, thermal shutdown threshold, or safe simultaneous AC charging and output. Buyers should request material declarations, flammability evidence where required, temperature-rise tests under the intended load combinations, protection-threshold data, abnormal-operation testing, cell and PCBA records, aging procedures, and final-sample inspection results.
6. Can the AJ45 be supplied for different mains-voltage regions?
Only the published 220–240V / 50Hz input should be treated as confirmed on this page. A 100–120V version, universal-voltage version, alternate plug, or market-specific configuration must not be assumed. Buyers should ask YULIDA to evaluate the exact target-country requirements, electrical architecture, plug system, tooling, labeling, test plan, certification scope, MOQ, and lead time before advertising a regional version.
7. What OEM and ODM options are available for the AJ45?
Standard OEM service starts at 500 pieces for logo and packaging on the existing AJ45 platform. Light customization, such as an approved housing color, documentation, packaging, or accessory change, generally starts at 1,000 pieces. AC input, plug structure, battery, PCBA, firmware, thermal design, built-in cable system, or enclosure changes are deeper ODM work and generally start at 2,000 pieces. Final MOQ, regional feasibility, samples, tooling, lead time, labeling, and certification scope must be confirmed in the quotation.
