Buying guides for phone cases, chargers, and accessories

Phone Balls explains what the labels on phone gear mean, including Qi2, USB Power Delivery, drop-test claims, and watt-hour ratings, so you can tell whether a case, charger, or power bank suits your phone before you order it.

What to check on the listing

Each kind of phone gear has one or two specs that decide whether it works with your phone. This table lists them, with the guide that explains each one.

Common buying mistakes

A charger can carry a big wattage number and still charge your phone slowly. Phones negotiate power over USB Power Delivery, and Samsung and Google phones only reach their faster rates with chargers that support PPS, which the USB-C fast charger guide explains along with the newer AVS feature Apple lists for the iPhone 18 Pro. The cable can hold things back too, and the USB-C cable guide explains the difference between a 60W and a 240W cable.

Wireless chargers sold as "Qi2 compatible" haven't necessarily passed certification, and a Samsung Galaxy needs a magnetic case before a Qi2 charger can hold it in place, as MagSafe and Qi2 explained sets out. Case listings lean on "military grade," and the case materials guide explains what that drop claim does and doesn't tell you. Power banks are the one item with legal limits on where they can travel, since they're banned from checked bags, so compare the watt-hour rating with the limits in power banks and flying before a trip.
