Fast chargers have become essential as phones, tablets and even laptops demand more power to keep up with daily use. Many new devices no longer include a charger in the box, so finding the best fast charger for you is important if you want reliable speed without damaging your battery. A good charger saves you time, keeps your devices powered during busy days and often supports multiple gadgets at once.
The best fast charger options now go beyond smartphones. Tablets like the iPad Pro, foldables such as the Galaxy Z Fold series and laptops with USB-C charging all benefit from higher wattage and newer standards like USB-C PD and GaN. Some models are compact enough to fit in your pocket, while others have several ports so you can power a laptop, phone and earbuds at the same time.
With so many different devices and charging standards, choosing the best fast charger depends on your setup and how you use it. This guide breaks down our top picks to help you find the right match for your gear.

What to consider before buying a fast charger
Before you start looking at specific chargers, it’s critical to determine three things: how many devices do you need to charge, how much power do they require and whether or not you’re planning on traveling with any of them.
The reason for the first question is simple. If you only need to charge a single device, like an iPhone or Android phone, it’s cheaper and usually more space-efficient to get a lower-wattage phone charger with one port instead of two or three. Next, it’s critical to figure out how much electricity your gadgets need because it doesn’t make sense to buy a power brick that pushes out more juice than your device can actually use. This may sound a bit tricky, but most major manufacturers will list a product’s max charging speeds in its tech specs, which is typically denoted by a specific wattage (15W, for example) or a quick-charge rating.
Unfortunately, very powerful or large laptops like gaming notebooks can suck a ton of juice (more than 140 watts), which means they may rely on more traditional power adapters with barrel plugs. This may result in them not being compatible with universal chargers. Some of these PCs may also support charging over USB-C, so even if a specific adapter can’t deliver its full power draw, it can still send over some energy — but it will do so at a slower rate compared to the laptop’s included charger. To get the best performance, using a fast charging cable, such as a USB-C cable, can make a big difference in maintaining consistent power delivery.
For frequent travelers, size and weight are often important considerations, because the bigger and heavier a charger is, the more annoying it will be to lug around. You’ll also want to think about other factors like support for international plugs, which can be a big help to anyone who regularly visits other countries. If you’re already traveling with power banks or a charging station, choosing a compact GaN charger can help streamline your gear.
Finally, you’ll want to figure out if your smartphone uses a proprietary charging standard or if it’s compatible with the USB Power Delivery spec (USB PD). For example, the OnePlus 13’s included SuperVOOC power adapter can send up to 100 watts to the phone. However, if you use a generic USB-PD charger, speeds top out at 45 watts. That’s still pretty quick, but not nearly as fast as OnePlus’ brick — and the same applies to devices with super fast charging support. Also, make sure your charging cable and connector are up to spec, as lower-quality accessories can bottleneck your charging speeds.
Fast charger FAQs
What is GaN?
When looking for chargers, you may notice that some are marked as GaN, which stands for gallium nitride. This is an important distinction because, when compared to older adapters that use silicon switches, GaN-based devices support increased power efficiency and output, allowing manufacturers to create more compact bricks that run cooler and support higher wattages.
Depending on the specific power output, GaN adapters can be 30 to 50 percent smaller and lighter than silicon-based alternatives. That might not sound like much, but when they’re sitting in a bag alongside a laptop and a half dozen other accessories you might have, cutting down on excess bulk and weight goes a long way.
Do fast chargers affect battery life?
Technically yes, because the process of sending a ton of watts into a gadget and potentially generating additional heat while doing so can decrease battery health over time. That said, modern devices and chargers use various protocols to ensure temperatures and power levels stay within preset limits — in large part to avoid damaging the product or creating a safety risk. At a base level, simply charging a gadget regardless of speed will cause degradation over time (nothing stays perfect forever, you know?). So as long as you use compatible chargers and cables, the impact of fast charging is generally quite negligible.
What’s the difference between a fast charger and a regular charger?
There isn’t a single generally accepted definition of fast charging. However, with power adapters capable of sending as little as five watts or less, it’s important to know how much juice your device is getting, especially if you need to recharge something quickly. So depending on who you ask (particularly when it comes to smartphones), any charger that can push out more than 15 to 18 watts is generally considered to be “fast.” That said, with some phones capable of receiving more than 100 watts and up to 240 watts for some laptops, it’s more important than ever to consider what devices you own before buying a new fast charger.
