You can generally get by using whatever charger came in the box with your device (provided one was included, which is no longer a given), be it a low-powered smartphone or a high-powered item like a gaming laptop. But if you’re anything like me and inevitably lose the original charger, or you need more ports or power for all your devices on the go and at home, the choices suddenly become less straightforward. What wattage do I need? Is GaN actually worth paying for? (Spoiler: yes!) Can the cheap, no-name charger that's on sale safely handle multiple devices over extended charging times?To find the best USB chargers for your phone, laptop, and other devices, we started by testing 20 different models (with plenty more to come), ranging from a 15W phone charger that came with a Samsung phone to 140W beasts, across a wide variety of brands including Anker, Baseus, Belkin, Ugreen, Cuktech, and more. Our charger testing goes beyond marketing claims, focusing on real-world performance, including sustained output over time, thermal performance, efficiency, idle power draw, and even a raw dollar-per-watt metric for those who just want the best bang for their charger buck.We found that most of today’s chargers are relatively efficient, safer, and smarter than ever. Even the cheap options handled basic charging without issue, particularly at lower wattages. But once you hit the 100W-plus range, heat and sustained output are much more important. Modern charging technologies like USB-PD, PPS, QC, and GaN have significantly improved charging speeds, efficiency, and size. However, chargers still can’t escape physics, and removing 140W of heat from something roughly the size of a deck of cards is still challenging.Picking a charger that gets the job done isn’t rocket science. Almost any modern charger will suffice, especially for the low-wattage devices. But if you’re looking to power laptops, tablets, or multiple devices at once, spending a bit more can get you more ports, better sustained performance, cooler temperatures, faster charging, and added peace of mind. After dozens of hours of testing, these are the best phone chargers, laptop chargers, and general USB device chargers we recommend.Quick List
