How to Choose the Best Travel Charger for International Travel
You're about to book a trip abroad and you realize your current charger won't work in the outlets at your destination — or it will, but only if you buy three different adapters and hope for the best. Choosing the best travel charger for international travel isn't complicated, but there are a few key things to get right. This guide walks you through exactly what to look for so you can travel confidently, fully charged.
1. International Outlet Compatibility
The most fundamental requirement for any international travel charger is that it actually works in the countries you're visiting. Outlet types vary significantly around the world — the flat two-prong plugs used in the US don't work in Europe, and European plugs don't work in the UK or Australia.
Look for a charger that works in a wide range of countries without requiring separate plug adapters. The NexCharger GaN 20W Travel Adapter works in 180+ countries, which covers the vast majority of international destinations travelers visit.
2. Number and Type of Ports
Modern travelers carry multiple devices. A good international travel charger should have enough ports to handle your full device lineup without requiring multiple outlets.
Look for:
- USB-C ports — essential for modern phones, laptops, and tablets
- USB-A ports — useful for older accessories and cables
- At least 3–4 total ports if you travel with multiple devices
The NexCharger GaN 20W Travel Adapter includes 2 USB-C and 2 USB-A ports, giving you the flexibility to charge up to 4 devices simultaneously from a single outlet.
3. GaN Technology vs Traditional Chargers
If you're comparing travel chargers, pay attention to whether they use GaN (Gallium Nitride) technology. GaN chargers are more efficient than traditional silicon-based chargers, which means:
- Smaller, more compact design
- Less heat generated during charging
- More power delivered in a lighter package
For travel, this matters. A GaN charger can replace multiple traditional chargers while taking up less space in your bag. It's one of the most meaningful upgrades you can make to your travel kit.
4. Size and Weight
A travel charger that's too bulky defeats the purpose. Look for a compact, pocket-sized design that fits easily in your carry-on, day bag, or even your jacket pocket. The best travel chargers are ones you barely notice you're carrying — until you need them.
5. Wattage and Charging Speed
Wattage determines how quickly your charger can power up your devices. For most travelers, a 20W charger is sufficient to fast-charge phones and keep tablets and laptops topped up. If you have a high-powered laptop with specific charging requirements, check the USB-C Power Delivery specs before purchasing.
6. Warranty and Return Policy
A travel charger is something you'll rely on heavily. Look for a brand that stands behind its product. The NexCharger GaN 20W Travel Adapter comes with a 30-day money-back guarantee, so you can try it risk-free. Fast global shipping means you can have it before your next trip.
