Frequently asked questions
- How powerful a charger do I need?
- A phone charges at full speed from a 20 to 30 W charger, a tablet from 30 to 45 W, a USB-C laptop needs 65 W and a powerful laptop 100 W or more; the required wattage is printed on the original adapter. A stronger charger does no harm, it delivers only what the device asks for. A weaker one charges slowly, or not at all in the case of a laptop.
- What is a GaN charger?
- A charger built with gallium nitride transistors instead of silicon. It is much smaller and lighter at the same power and runs cooler, which makes it ideal for travel and for charging a laptop. Functionally it is no different from a conventional charger; what matters is still the wattage and the supported standards.
- What do Power Delivery and Quick Charge mean?
- They are fast-charging standards: USB Power Delivery (PD) runs over USB-C and is supported by today's phones, tablets and laptops; Quick Charge (QC) is an older standard of some Android phones over USB-A. The charger and the device negotiate the highest standard they share. If the charger does not know the device's standard, it charges at basic power.
- Does a multi-port charger charge every device at full power?
- No, the stated wattage is the total and it is shared when several devices are connected. For every charger we state how the power is split, for example 100 W in total means 65 W and 30 W with two devices. If you are charging a laptop, expect a phone on the second port to reduce the laptop's share.
