A USB extension cable seems simple until devices start dropping. Here is how USB-A, USB-C, active, and powered extensions differ, and how far each can run.
Every USB-C adapter solves one job: OTG, couplers, USB-A dongles, video Alt Mode. Which ones quietly limit speed or power, and three checks before buying.
SPR AVS is the USB PD 3.2 feature behind iPhone 17 fast charging. What it is, how it differs from PPS, and what it means for the charger you buy.
PPS vs AVS: both adjust charging voltage, but they solve heat differently. The spec differences, who uses which, and what it means for your next charger.
Most homes still have a few devices that need a micro USB cable. Here is how to pick one that charges fast and lasts, plus the specs that matter.
Every iPhone Air case fights the reason the phone exists: 5.9mm of titanium. When a thin or magnetic shell earns its place, and how to protect the lens.
The right iPhone 18 charger is a 45W USB-C unit you may already own. Which charger to buy, which cables work, and what Apple will include in the box.

How to get full iPhone 17 charging speed: the settings that matter, the habits that help, and fixes for slow or intermittent charging.
A charger is not one product category — it is several. The right USB-C charger for an iPhone 17 is not the right pick for a MacBook, a power bank is not a wall plug, and a MagSafe pad trades speed for convenience. Our guides split them the way you actually shop: by device, by standard, and by wattage you can verify.
Start with what you own. For a recent iPhone, the iPhone 18 charger guide and the iPhone 17 charging guide cover the adapters and cables worth buying. For everything else — the micro USB cable still living in your drawer, the USB-C adapter that will not slow your phone down, the 10000 mAh power bank that flies carry-on legal — there is a guide for that too.
Three checks filter almost everything on the phone accessories shelf. Does the listing name a standard (PD, PPS, Qi2) or only a wattage number? Is the charging cable in the box certified, or is it the freebie that will throttle your fast charge? And does the seller exist when you need the warranty? A no on any of those costs you more than the price gap between brands.
Every charging cable and every phone charger we recommend is picked from published specs and USB-IF certification status, never from brand press releases. Phone accessories guides follow the same rule. Where we have not tested a unit ourselves, we say so.
