In idea, charging your cellphone, pill, or laptop computer must be fairly easy: Plug a cable into the gadget, plug the cable right into a charger, await the gadget to cost, and be in your manner.
But by no means underestimate the tech business’s capability to complicate. What must be a senseless interplay as an alternative includes a plethora of competing plugs, codecs, and necessities, all in service of topping up your tech’s batteries sooner than earlier than.
Lately I’ve been getting loads of emails about one of the simplest ways to cost numerous devices on the go, which makes me suspect loads of you might be itching for a trip. What higher time, then, to demystify this matter in glossary type? With a lot jargon to contemplate, breaking down every component is one of the simplest ways to make sense of all of it.

Cable fundamentals
With the exception of gaming laptops and super-cheap Windows laptops, most trendy gadgets will use one of many following charging connectors:
USB-A: The giant, rectangular connector that’s ubiquitous on older laptops (and, nonetheless, many new ones that aren’t made by Apple).
Micro-USB: Flat on one facet and sloped on the opposite, discovered on older Android telephones and a good variety of equipment. Cable sometimes has a big, rectangular USB-A connector on the opposite finish.
USB-C: Reversible connector that’s flat on high and backside with rounded sides, now the usual on Android telephones, iPads, current MacBooks, and lots of Windows laptops. Cables can both have USB-A on one finish or USB-C on each.
Lightning: Apple’s proprietary connector for the iPhone, iPad, and AirPods. Can have USB-A or USB-C on the different finish of the cable. The firm appears to be steadily changing Lightning with USB-C, for example on the 10th-generation iPad and latest Apple TV remote.

Fast cost jargon
While there’s no official business definition for quick charging, Apple loosely defines it as as replenishing 50% of the battery in roughly 30 minutes. To get this stage of charging velocity, you’ll want a Lightning to USB-C cable (for Apple) and USB-C to USB-C cable (for Android).
Assuming you’ve received the requisite charging cables, you’ll additionally want a suitable charger or moveable energy financial institution to allow quick charging. That’s the place issues get difficult, as you’ll typically be confronted with quantity and alphabet soup whereas looking for both kind of product. Here’s what to be careful for:
USB Power Delivery (USB-PD, or simply PD): Industry customary for quick charging, supported by the iPhone and most notable Android telephones. Requires a USB-C connection on the charger.
Quick Charge (or QC): Proprietary quick charging format from Qualcomm. Has some advantages over PD however is omitted by some cellphone makers (most notably Apple and Google) as a consequence of licensing prices.
Programmable Power Supply (PPS): Feature on some USB-PD chargers that may dynamically alter present and voltage to make charging extra environment friendly, resulting in sooner cost occasions. It’s meant to shut the hole in charging effectivity between Qualcomm’s QC and the USB-PD customary.
PowerIQ: Proprietary Anker expertise that mixes PD and QC on a single charging port, permitting quick charging with both format. On multi-port chargers, it may possibly additionally dynamically alter charging speeds based mostly on the calls for of every port.
Wattage: A unit of energy that describes how a lot vitality a tool consumes over time. In the context of chargers and energy banks, it supplies a tough gauge of how shortly they will cost a tool.
20W: The most secure guess for wattage when shopping for a cellphone charger. While the iPhone 8 via iPhone 11 provide quick charging with 18W chargers, the iPhone 12 and up require a 20W USB-PD charger. (That mentioned, tests by PhoneArena and others have discovered 18W chargers to be practically as quick, even with newer fashions.)
60W: The most charging wattage for a lot of laptops with USB-C connectors, due to this fact minimal to focus on when shopping for a laptop computer charger. Note, nevertheless, that newer MacBooks can charge even faster, and we’re beginning to see 240W for some gaming laptops. Check your laptop computer’s capabilities earlier than shopping for a charger to match.
mAh: Stands for milliamp hour, usually used to convey the battery capability of telephones and moveable energy banks. The iPhone 13 has a 3,227 mAh battery, whereas the Samsung Galaxy S21 has a 4,000 mAh battery. Power banks typically are available capacities of 5,000 mAh, 10,000 mAh, or 20,000 mAh.
GaN: Stands for gallium nitride, a semiconductor materials that enables for smaller chargers. GaN adapters are inclined to value somewhat greater than their bigger counterparts.
Wireless weirdness
Qi: Wireless charging customary that’s turn into desk stakes on higher-end telephones. Lets you cost by inserting the cellphone on a suitable charging mat or stand, albeit at a slower fee than with a cable.
MagSafe: Refers to numerous proprietary Apple charging programs, together with a magnetic charging puck for iPhones and a snap-in connector for pre-2016 and late 2021 MacBook Pros. The MagSafe charger on iPhones 12 and better helps quick charging at 15W when paired with a 20W USB-PD 3.0 adapter.
Apple
“Made for MagSafe”: Refers to Apple-approved, third-party magnetic chargers that assist 15W charging speeds on the iPhone 12 and better. Other magnetic chargers have speeds of 7.5W as an alternative, even if they advertise MagSafe compatibility.
7.5W: The most iPhone charging velocity when utilizing a Qi mat or stand with out official MagSafe assist.
Super Fast Wireless Charging: Proprietary format for wireless chargers from Samsung, able to charging compatible Galaxy phones at as much as 15W.
OnePlus
Warp Charge: Proprietary fast-charging format for OnePlus telephones. The firm’s latest 50W wireless charging stand can absolutely cost a drained OnePlus 10 Pro in 47 minutes.

Putting all of it collectively
Now that you simply’re a grasp of quick charging jargon, you possibly can extra simply purchase a charger or moveable energy financial institution that meets your wants. You’ll know, for example, {that a} 20W charger with USB PD 3.0 and PPS assist will allow you to wish to cost an iPhone as quick as potential, and that solely Apple’s personal MagSafe Battery Pack can recharge an iPhone at speeds near these of fast-charging cables. And in case you spot a charger or energy financial institution that’s so much cheaper than the remainder, you’ll hopefully have an eye fixed for what options it may be lacking.
