How to choose a GaN charger

A gallium-nitride (GaN) charger does the same job as an old silicon charger in a smaller, cooler package. Choosing one is a wattage decision first and everything else second.

Step 1 — Add up what you charge at once

A laptop typically needs 45–65W, a tablet 18–30W, a phone 15–25W. The VoltCore 65W covers a laptop plus a phone only if the laptop is not drawing its full 65W at the same time — total output is shared across ports. If you charge a 65W laptop and a tablet together at full speed, you need a higher total output than 65W.

Step 2 — Count the ports you actually use

VoltCore gives you 2× USB-C and 1× USB-A. Use USB-C for anything that fast-charges; keep USB-A for older cables and low-power accessories. One port you never use is not a feature.

Step 3 — Check the plug and the protection

Foldable US plugs travel better and break less. Over-voltage, over-current and temperature protection are not optional extras — they are the difference between a charger and a risk. VoltCore lists all three in its specification sheet.

The mistake to avoid

Buying on watts alone and ignoring the port split. A 65W single-port charger and a 65W three-port charger are different products when two devices are plugged in. Read the specification sheet, not just the headline number.
