Electronics

Electronics sorted by where you use them, from the pocket to the living room:

at the pocket end sit mobile phones, chargers and power banks included, and smartwatches, which only make sense beside the phone they pair with. Computers and tablets and e-readers are the work and study end, with monitors, printers and parts filed under computers. The living room splits into television and film, audio and video games and consoles. Video and photography holds cameras and lenses alongside home security cameras, and drones and RC cars go under remote control.

The phone you own decides the smartwatch, and the disc drive decides the console:

both rule models out before price does. An Apple Watch needs an iPhone to set up and run, and a Galaxy Watch on Wear OS will not pair with an iPhone at all. Consoles have their own fork. A digital edition has no disc drive, so it cannot play the used game discs that are the cheapest way to build a library, and downloaded games stay on the seller’s account rather than travelling with the machine. With any older model, check that the maker still sends it software updates; a phone that no longer gets security patches is a poor home for a banking app.

The IMEI and the invoice behind a used phone or laptop:

together they say where the device came from. Dial *#06# on a phone to show its IMEI, check it matches the number on the box and in the settings, and enter it on SUTEL’s validation platform, which shows whether that phone or tablet has been reported lost or stolen and blocked. Ask for the electronic invoice too: its date tells you how old the device really is and that it left a shop here. Gifts and devices brought from abroad never had one, so a missing invoice is not a red flag, but then the device has to speak for itself. Before paying, have the seller sign out in front of you. An iPhone or iPad still tied to someone’s Apple ID, or an Android phone under Google’s factory reset protection, cannot be set up by anyone else.

Batteries, screens and ports, where used electronics wear out:

the battery goes first. An iPhone shows its battery health in settings, and a phone or laptop whose screen is lifting or whose back is bowed has a swollen battery and is not worth taking home. Recent iPhones also flag a non-genuine replacement screen in settings, which should show in the price. On consoles, test every controller for drift and put a disc in; on laptops, open and close the hinge and try the charging port with the original charger. Cheap copies of AirPods and Galaxy Buds are common, so check the serial number with the maker before handing over money for a sealed box. Consoles and camera lenses lose value slowly; phones and laptops drop with every new model and again as the battery ages, so price a two-year-old phone for the battery it has left.

Model, storage and IMEI in a phone or laptop ad:

those three answer most of the first messages. Write the exact model and storage in the title, say whether the phone is unlocked and works on any local network, and give the battery health figure. Photograph the screen switched on, the edges and the box label. Mention any repair or replaced screen, and offer to forward the invoice with your cédula number covered. Whoever sells a phone or laptop has usually just upgraded, so the box and charger are often still in a drawer; including them is what lets a buyer in Grecia or Turrialba decide the trip is worth making.
