AJ11 Dual Cable Power Bank with LED Display | 22.5W OEM

Frequently Asked Questions: AJ11 Dual Cable Power Bank with LED Display

1. How is the AJ11 different from the AJ09 if both have dual built-in cables and an LED display?

While both share the dual-cable concept, the AJ11 is designed as a larger-capacity, travel-oriented model. The key differences: the AJ11 offers a 20,000mAh option (versus AJ09’s 10,000mAh only), uses a rectangular body (109×64mm) instead of square, supports 18W PD input for faster self-recharging, and includes a 12V/1.5A output profile that the AJ09 does not. The LED display on the AJ11 is positioned on the narrow edge rather than the front face, making it visible when the power bank is standing upright or lying flat. Think of the AJ09 as the everyday carry dual-cable charger and the AJ11 as the extended-capacity travel companion.

2. Can the 20,000mAh AJ11 fully charge a tablet or laptop via the Type-C cable?

The AJ11’s Type-C cable outputs up to 22.5W (5V/3A, 9V/2A, 12V/1.5A), which is sufficient to charge most tablets including iPad, iPad Mini, and Galaxy Tab series at near-maximum speed. It can charge an iPad 10th generation from 0% to approximately 60% on a single 20,000mAh charge. However, the AJ11 cannot charge full-size laptops that require 45W or higher USB-C PD — for those devices, consider YULIDA’s AJ25 100W TFT power bank. The AJ11 is optimized for smartphones, tablets, and small accessories. For road warriors who carry both a phone and a tablet, the 20,000mAh AJ11 with its dual built-in cables means zero extra cords to pack.

3. What information does the LED display show and how does the AJ11’s rectangular body compare to the square AJ09 in everyday handling?

The AJ11’s edge-mounted LED display shows precise battery percentage from 0-100, with a charging status indicator that distinguishes between standard charging (steady digit) and fast charging (flashing digit). When a device is connected and the AJ11 successfully negotiates a PD or QC fast-charging protocol, the display digit flashes twice before settling — confirming maximum speed without checking the phone. The edge-mounted position means the display faces upward when the power bank is lying flat, making it glanceable on a desk or nightstand. In terms of ergonomics, the AJ11’s 109×64mm rectangular shape with 24mm thickness feels closer to a traditional smartphone in hand — more natural to grip than a square body — and fits more naturally into slim bag pockets and laptop sleeve accessory compartments. The longer shape also provides better weight distribution, so the AJ11 feels balanced rather than dense.

4. Why does the AJ11’s Type-C cable output support 12V/1.5A when the AJ09 does not?

The 12V/1.5A (18W) output profile on the AJ11’s built-in Type-C cable enables compatibility with devices that negotiate at 12V rather than 9V — including certain Samsung tablets, Nintendo Switch (handheld mode), and some drone batteries. The AJ09 omits the 12V profile because its 10,000mAh single-cell configuration has a lower voltage ceiling. The AJ11’s dual 146074 cells in series provide a higher native voltage that makes 12V output more electrically efficient, reducing the boost conversion losses that would otherwise generate excess heat. For B2B buyers targeting markets where Nintendo Switch or drone accessories are popular, the AJ11’s 12V support is a meaningful spec advantage.

5. How long does it take to recharge the 20,000mAh AJ11 from empty?

With an 18W PD wall charger (not included), the 20,000mAh AJ11 recharges from 0% to 100% in approximately 5.5 to 6 hours via the Type-C input port. The 10,000mAh version recharges in about 3 to 3.5 hours. Both versions support pass-through charging, so you can recharge the AJ11 while it simultaneously charges your devices. The LED display shows the recharge progress in real time, counting up from the current percentage. For faster recharging, the AJ11 also accepts 12V/1.5A input, which is slightly more efficient than 9V/2A and can reduce total recharge time by 15-20 minutes on the 20K model.

6. Are both built-in cables on the AJ11 replaceable if they eventually wear out?

The built-in Type-C and Lightning cables on the AJ11 are integrated into the internal PCB through soldered connections and are not designed for user replacement. However, YULIDA’s accelerated life testing shows the cables exceeding 10,000 insertion cycles and 8,000 bend cycles before any electrical degradation — equivalent to over 5 years of daily use. As a failsafe, the AJ11 includes a standard Type-C port and a USB-A port, so even if a built-in cable were to fail, the power bank remains fully functional with external cables. For OEM clients concerned about long-term reliability, we can provide the cable cycle test data as part of the quality documentation package.

7. What OEM customization options make the AJ11 compelling for corporate gift and promotional markets?

At MOQ 500, the AJ11’s large flat surfaces (109×64mm) provide an expansive canvas for branding — approximately 70cm² of printable area, larger than most power banks in its class. The LED display bezel area can be color-matched to corporate brand guidelines. The dual built-in cables offer a unique branding opportunity: each cable can be a different color representing your brand’s primary and secondary palette. For corporate gift programs, the AJ11’s 20,000mAh capacity and dual-cable design communicate generosity and thoughtfulness — recipients get a premium-feeling product that works with both their iPhone and Android devices without hunting for cables. Custom packaging with company logo and a personalized thank-you insert card is available with no additional tooling charge for orders over 1,000 units.
