Gate areas in Terminals A and B both have a Tech on the Go
Tech on the Go sits airside in SJU’s main concourse, handy if you realize at A10 or B5 that your charger died overnight. It runs typical airport hours, roughly from the first departures to the last evening flights, so you can usually grab gear even on early JetBlue or late Spirit banks.
Expect national-brand accessories at airport markups: phone cables around $20–$30, basic wired earbuds in the $25 range, and name-brand power banks often pushing $50+. You’ll see rows of Lightning, USB‑C, and micro‑USB cords, plus wall plugs and a few multi-country adapters that work with Caribbean and US outlets.
Inventory leans hard into last-minute needs: screen protectors cut to fit iPhone and Samsung models, tablet cases for common sizes like 10.2" iPads, and small Bluetooth speakers whose boxes actually list wattage and battery life. They also carry over‑ear headphones in the $60–$150 band, including a few noise-cancelling models that beat what airlines hand out in coach.
Selection skews mainstream brands you’ll recognize from big-box stores, along with some cheaper house-label cables near the cash wrap; employees will usually point you toward the mid-range option if you ask at 7 a.m. before that AA mainland hop. Returns and exchanges typically have to happen the same day of purchase, on-site, with the printed receipt.
One practical tip: test everything at the counter using the sample charging block or your own phone before you walk back to A4 or B8; swapping a dead cable is painless at the register and annoying once you’re already in the boarding line.
