Power bank HyperDrive HJ245B 27000 mAh Silver, 4-device simultaneous charging

The HyperDrive HyperJuice 245W USB-C Battery Pack (Power bank HyperDrive HJ245B) is a 27000 mAh, 100 Wh portable power bank in a silver finish designed for extended mobile charging. It supports up to four USB‑C devices at once via two 100W Power Delivery ports and two 65W Power Delivery ports, and includes an OLED screen that displays remaining capacity and per‑port charging information. The battery pack is designed to meet airline safety limits and supports passthrough charging at 100W for faster recharging of the unit while powering connected devices.

Advantages

The large 27000 mAh capacity provides multiple full charges for phones, tablets and even several charges for laptops or drones, making it a practical choice for travel, remote work or multi‑device users. Dual 100W USB‑C ports and two 65W USB‑C ports allow simultaneous charging of four devices with fast Power Delivery; the OLED display offers real‑time status for capacity and port usage. Built‑in protections guard against over‑current, over‑voltage, over‑temperature and short circuits, and the unit supports modern fast‑charge protocols including PD 3.0, QC 4.0+ and PPS for broad device compatibility.

Suitable for

• Business travelers and road warriors who need multiple device charges on the go
• Photographers and drone operators needing portable recharges for cameras and drones
• Remote workers who use laptops, tablets and phones away from mains power
• Gamers or console users who require portable power for handheld consoles or accessories

When it may not be suitable

Because the pack is a high‑capacity battery designed to meet airline safety limits (100 Wh), it is bulkier and heavier than small phone power banks and may feel overpowered for users who only need an occasional single smartphone top‑up. It also relies on USB‑C Power Delivery for maximum charging speeds; devices without PD, QC or PPS support will charge more slowly.

How to use

Connect devices to the USB‑C outputs using compatible cables; the pack will negotiate the appropriate Power Delivery profile for each connected device. To recharge the battery pack, connect a 100W USB‑C PD charger to the input port to take advantage of passthrough charging and faster recharging times. Monitor the OLED screen to check remaining capacity and per‑port voltage/current while charging or discharging.

What to consider before purchase

• If you need the fastest charging speeds, verify your devices support PD, QC or PPS standards
• Consider the pack’s weight and physical size if you prioritise minimal carry weight
• For airline travel, check airline rules for carrying lithium batteries, though this unit is designed to comply with 100 Wh limits

Usage recommendations

Use certified USB‑C PD cables and a 100W USB‑C PD wall charger to recharge the HyperDrive HJ245B quickly. Distribute high‑draw devices across the 100W and 65W ports to balance output and avoid exceeding individual port limits.
