How to inventory your electronics

Electronics are the one category where a home inventory earns its keep the fastest — a stolen laptop or a flooded TV is exactly the kind of loss an insurer wants proof for — and also the one category most likely to turn a simple list into an afternoon spent squinting at a serial number sticker on the bottom of a router nobody has touched in three years. The fix isn't tracking less. It's noticing that electronics are actually asking you two different questions, and only one of them needs that much detail.

Two different questions, wearing one category

The first question is "could I prove I owned this." That's an insurance and warranty question, and it only applies to a short list of things: the items expensive enough that losing them would actually hurt, and old enough or few enough that you could plausibly forget the details by the time you needed them. The second question is "do I already have one of these." That's a duplicate-buying question, and it applies to a completely different, much longer list — chargers, cables, adapters, the accessories that pile up one small purchase at a time. Treating both questions the same way is what makes an electronics inventory collapse. Proving ownership needs real detail. Not re-buying a USB cable needs almost none.

What actually earns a serial number and a photo

Keep this list short on purpose: laptops, phones, tablets, TVs, game consoles, cameras, monitors, and anything else you'd genuinely notice the cost of replacing. For each one, four things are worth having — the brand and model, roughly when and for how much you bought it, a photo of the device itself, and a photo of the serial number where the sticker actually is, usually on the underside or the back. A receipt or order confirmation is the strongest proof of all if you can find it, but the photo of the serial sticker matters even without one, because it's the detail most insurers and manufacturers actually ask for and the one nobody can remember from memory under pressure.

What to skip entirely

Nearly everything else. A charging cable doesn't need its own serial number, its own entry, or really its own name — what's worth knowing is roughly how many of a given type you have and where they live, not which specific cable is which. The same goes for the manual that came in the box, the twist tie, the little bag of screws: none of it is what an insurer or a future you will actually go looking for. The instinct to log a device "properly" — full spec sheet, every port, every accessory — is exactly what turns a fifteen-minute pass into an abandoned project. Detail belongs on the short list of things worth proving you own. Everything else just needs to be findable.

A photo of the sticker beats typing the number

A serial number is usually twelve to twenty characters of letters and digits in a small font, and typing it by hand is where most people give up or get it wrong. A photo of the sticker, taken once, is both faster and more reliable — you're never relying on your own transcription being correct months later when you actually need it. Say the brand and model out loud instead of typing that part too; talking through what something is takes seconds, and it's a smaller ask than sitting down to type a description for a dozen devices in one go.

When to actually update it

Two moments, and only two. Right after you unbox something new and before the packaging goes in the recycling — that's the cheap moment to photograph the serial number, because it's the last time it's sitting right there in good light rather than tucked under a desk. And right before you sell, recycle, or hand down an old device — that's the moment to notice the charger and cable that came with it and are now unaccounted for, since accessories for a device you no longer own are some of the easiest things in a house to end up buying a second time without noticing. Kept's idle-days tracking is built for exactly that gap: an HDMI cable or a charger nobody has touched since the device it belonged to left the house shows up as idle on its own, and the check-before-you-buy search catches you before a matching one comes home to sit next to it.

What it looks like when it works

Not a spreadsheet with a row for every cable in the house. It looks like a short, genuinely useful list for the handful of devices an insurer would actually ask about — proof ready before you need it, not assembled in a panic afterward — and a drawer of chargers and adapters you no longer have to dig through and guess about before buying one more.
