Is 30W enough to charge a laptop?

It will slow-charge or maintain many ultraportables and keep them topped up under light use, but it is below the 45W to 65W most laptops want for full-speed charging.

What devices can this charger fast charge?

Any USB-C phone or tablet that supports USB Power Delivery, including most recent iPhones, Samsung Galaxy phones and iPads. It also charges accessories like earbuds and power banks.

Does it come with a USB-C cable?

Chargers in this class usually ship as the adapter only, so plan on using your own USB-C to USB-C or USB-C to Lightning cable.

Is GaN worth it over a regular charger?

GaN lets the charger run smaller and cooler at the same wattage. At $29.99 it costs little more than a standard 30W charger, so the size benefit comes cheap.

When is the best time to buy it?

At $29.99 as of November 7, 2026 it is already near the bottom of the 30W GaN range. Watch for bundle or site-wide discounts around Black Friday and back-to-school.

Our take on the StarTech 30W USB-C Wall Charger Portable GaN

The StarTech 30W USB-C Wall Charger is a compact GaN charger with folding-style portability and a single USB-C output that runs from 5V to 20V, so it can top up a phone, tablet or a small laptop. GaN internals keep it smaller and cooler than older silicon chargers of the same wattage. At $29.99 at Newegg as of November 7, 2026, it sits at the low end of what 30W GaN chargers cost, with two stores pricing it new.
