Power bank YENKEE YPB2145 — 20,000mAh, USB-C PD 45W, dual USB-A QC, LED display

Power bank with a 20,000 mAh capacity and up to 45W output, designed to fast-charge mobile phones, tablets and laptops. The USB-C Power Delivery port supports full laptop charging at up to 45W; a high-quality USB-C to USB-C cable (Gen.1/Gen.2) is recommended but not included. The USB-C input also enables fast recharging of the power bank itself in about 3 hours. A USB-A output supports QC 2.0 and QC 3.0 for accelerated charging of compatible devices. Dual outputs allow two devices to be charged simultaneously, while intelligent power management detects the connected device and adjusts output accordingly. A digital LED display indicates remaining battery capacity in real time.

Advantages

High 20,000 mAh capacity provides multiple full charges for smartphones and substantial additional runtime for tablets and laptops. Up to 45W Power Delivery via USB-C allows charging of power-hungry devices, including many laptops. Fast recharging of the power bank through USB-C reduces downtime to approximately 3 hours. Dual outputs (USB-C and USB-A) with QC support enable simultaneous charging of two devices and faster charging for compatible phones and accessories. Six layers of protection (overvoltage, short circuit, overcharge, overdischarge, overload and overheating) and intelligent charge management improve safety for both the power bank and connected devices. A digital LED display offers clear, real-time battery level information.

Connect devices to the USB-C output or USB-A outputs to charge; the power bank will automatically detect device requirements and adjust output. For charging laptops, use a high-quality USB-C to USB-C cable rated for Power Delivery. Do not expose the power bank to water or extreme temperatures, and follow the device safety instructions for best results.

Recommendations

Use a certified USB-C to USB-C cable (Gen.1/Gen.2) for laptop charging and a compatible high-wattage wall adapter to enable the fastest recharge and output performance. Store the power bank in a cool, dry place and avoid prolonged exposure to heat to preserve battery life and safety.
