Choose One Charger for All Your Devices: A multiport travel charger can power a phone, tablet and laptop from a single wall outlet. Before buying one, check the charging requirements of your devices and the number of ports you need. A charger with several connectors is useful only if it supplies enough power to support your devices at the same time.
Check the Total Wattage Before Buying: Wattage determines how much power a charger can provide. A phone may need much less power than a laptop, so check the maximum charging requirement of your most demanding device. USB Power Delivery supports power levels up to 240W under its specifications, although individual chargers and cables have their own limits.
Look for USB-C Power Delivery Support: USB-C Power Delivery helps compatible chargers and devices negotiate suitable charging power. Check that the charger supports the protocol your laptop, tablet or phone needs. A USB-C connector alone does not guarantee the highest charging speed. Also check the manufacturer's specifications for maximum output and compatibility with your particular device.
Understand How Power Is Shared Across Ports: A charger may advertise a high total output, yet each port may deliver less power when you connect several devices. Check the charging table provided by the manufacturer. It should explain how power is divided between ports when multiple devices charge together. This helps you avoid choosing a charger that cannot meet your laptop's needs.
Consider GaN Chargers for Travel: Gallium nitride (GaN) technology allows manufacturers to build compact power electronics, making it useful for high-power chargers designed for travel. Compare the charger's size, weight, plug design and supported output before choosing one. A compact model can save bag space, although its actual portability depends on its power rating and overall construction.
Check Plug Compatibility and Safety: International travellers should check whether a charger supports the electrical supply at their destination and whether they need a separate plug adapter. Buy from a reputable brand and check its safety certifications and protection features. If you need a laptop charger, also confirm that the included cable supports the required power level.
Match the Charger to Your Travel Routine: Choose a charger based on the devices you carry most often. A phone and tablet may work well with a lower-power model, while laptop users should prioritise sufficient USB-C output. For flights, check your airline's current rules for power banks and spare batteries; these rules differ from those for ordinary wall chargers.
