Vention 20000mAh Power Bank — 22.5W Fast Charging Portable Charger with LED Display

The Vention 20000mAh Power Bank (FHLB0) is a high-capacity portable charger built for users who need to keep multiple devices powered across full days or extended trips without access to a wall socket. It delivers 22.5W fast output via USB-A and 20W Power Delivery via USB-C, covering a broad range of smartphones, tablets, and earphones. Additionally, a precise LED percentage display gives users an accurate reading of remaining capacity rather than vague indicator lights.

High Capacity for Multi-Day and Multi-Device Use

The 20000mAh lithium-ion cell delivers substantial backup power for real-world use. It charges an iPhone 15 Pro approximately four times, a Samsung Galaxy S22 Ultra around three times, a Xiaomi 12 up to 3.2 times, and an iPad mini roughly 2.7 times on a single charge cycle. For users managing two or three devices throughout a long travel day, that capacity removes the need to hunt for a power outlet between legs of a journey.

The LED display shows remaining battery as an exact percentage in real time. Consequently, users can confirm available charge before leaving home and make informed decisions about when to recharge the unit itself. The display also shows active charging status for connected devices, removing guesswork about whether a port is delivering power.

Dual-Way Fast Charging — In and Out

The FHLB0 supports fast charging in both directions. On the output side, the USB-A1 port delivers up to 22.5W, compatible with SCP, QC 3.0, FCP, AFC, and Apple 2.4A protocols — covering the majority of Android flagships and iPhones currently in use. The USB-C port outputs up to 20W via Power Delivery, which is the optimal input speed for iPhone 12 through iPhone 15 models and many USB-C Android devices. Meanwhile, the USB-A2 port provides a standard 10W output for lower-draw accessories such as earphones, smartwatches, and Bluetooth speakers.

On the input side, the USB-C port accepts up to 18W, recharging the power bank from empty to full in approximately six hours with a compatible 18W adapter. The Micro-USB input offers a 5V/2A backup option when a USB-C cable is unavailable. Furthermore, the FHLB0 supports simultaneous input and output charging, allowing users to top up the power bank while it continues charging a connected device.

The PC and ABS housing is slim and lightweight relative to its capacity class. CE, FCC, RoHS, and MSDS certifications confirm that the unit meets international electrical safety and environmental standards. Comprehensive built-in protection covers short circuits, overvoltage, overcurrent, over-discharge, reverse polarity, and overpower conditions.
