Charging speed depends on the port you use, the cable, and how many devices are charging at once. Most slow charging can be fixed with the checks below.
Use the right port
- USB-C ports (PD, Power Delivery) are the fastest on Jackson products. They charge most recent phones, tablets and some laptops quickly.
- USB-A ports (QC, Quick Charge) suit older phones, earbuds, watches and accessories.
- If your device has a USB-C socket, use a USB-C port and a USB-C to USB-C cable for the fastest charge.
Check the wattage
Each Jackson product shows its USB output on the box and product page, for example 20W, 30W, 45W or 60W. A higher number can charge bigger devices faster.
The USB power is shared between the ports. On many Jackson powerboards and travel adaptors, when you use more than one USB port at the same time the total USB output drops to 15W, so each device charges more slowly. For the fastest charge, charge one device at a time.
Try these steps
- Unplug other devices from the USB ports and charge one device on its own.
- Try a different cable. Damaged, very long or low-quality cables can slow charging. Fast charging usually needs a cable rated for it.
- Use the cable that came with your device, or a USB-C cable rated for Power Delivery.
- Check your device's settings. Some phones slow charging when they're hot, almost full, or in an optimised or battery-saving charging mode.
- Let your device cool down if it's warm, then try again.
