I vary my travel kit depending on where I’m going, but there are a few piece of gear that are non-negotiable. Satechi’s GaN Travel Charger is one of those items, and it’s currently on sale during Amazon’s autumnal sale (aka Prime Big Deal Days). The four-port charger comes with modular adapters that snap into the charger itself and allow you to plug it directly into U.S., European, Australian, and U.K outlets . I’m writing this story while traveling in Croatia, and you can see the charger plugged into a European outlet below. Satechi GaN Travel Charger, $95.99 (Was $119.99) Brandt Ranj / Popular Science See It Having a single charger that can top up all of my devices simultaneously is hugely important on trips where plugs may be few and far between. I also feel better about using a charger that plugs into a wall rather than using a converter or adapter as there’s no additional accessory between my devices and the power outlet. Plus, Satechi’s charger offers massive power output. Its top two USB-C ports can deliver up to 140 watts of power, while the third and fourth USB-C ports can output up to 45 watts. When multiple devices are plugged in simultaneously, the charger will split how much power it sends to each port based on the demands of your devices. Knowing I can recharge my smartphone, tablet, or laptop at their top speed offers peace of mind as I plug them in before heading out for the day. If you travel often—especially in a larger group—don’t skip this deal. And remember, if you don’t have an active Amazon Prime subscription, you can sign up for a free, 30-day trial here.
