          Orders and shipping

          What happens between placing an order and it arriving, and where the tracking comes from.

          1. You place the order Orders placed before 5pm CST on a business day are processed that same day. Anything after that goes out the next business day.
          2. We pick and pack it Everything ships from our own warehouse at 3030 Commercial Ave, Northbrook, Illinois — not a third party, which is why the cut-off can be that late.
          3. It leaves us Primarily USPS. Your tracking number is emailed the moment the label is scanned, so a number that shows nothing yet usually means it is still on the truck to the depot.
          4. It arrives Two to five business days anywhere in the US on standard shipping. Express is a three-day service.

          Your tracking number arrives by email — we do not hold it anywhere else, so if the email has not come, check spam before anything else. Tracking that has not updated for a couple of days is almost always a missed scan rather than a lost parcel — it catches up at the next depot. If it has been still for more than four business days, email us the order number and we will chase it from our end.

          You can also check any time with the order tracker.

          Charging questions

          The things people ask us most about how charging actually behaves.

          Three things decide the speed and the slowest one wins: the charger, the cable, and what the phone will accept. A 65W charger with a 20W cable gives you 20W.

          Phones also taper deliberately. Above roughly 80% the rate drops to protect the battery, and it drops again when the phone is warm.

          No. USB-C Power Delivery negotiates before any power flows — the device asks for what it wants and the charger supplies only that. A 100W charger gives a pair of earbuds exactly what they request.

          Buying more wattage than you need costs you nothing but money.

          Gallium nitride replaces silicon in the charger's switching components. It wastes less energy as heat, so the same output fits in a noticeably smaller body.

          In practice: a GaN charger is smaller and runs cooler than a silicon one of the same wattage. It does not charge faster on its own.

          Because it is showing what your device is drawing at that moment, not what the cable can carry. It falls as the battery fills, when the phone is warm, and when the screen is on.

          A number lower than the rating late in a charge is the system working correctly.

          Laptop charger to phone: yes, the phone takes only what it asks for.

          Phone charger to laptop: usually not enough. Most USB-C laptops want 45W or more, and below that they may hold their level but not gain charge while you are using them.

          No, but it does run warmer than a cable, and sustained heat is what ages a battery. If you charge overnight on a pad, keep it out of direct sun and off soft surfaces that trap heat.

          Making a warranty claim

          Two years from purchase, on every product. Sending these four things in the first email is what makes it quick.

          1. Find the SKU. It is printed on the product and on its box, and searching it at the top of this page confirms you have the right one.
          2. Have your order number ready. It is on your confirmation email. If you bought through a retailer, the receipt works instead.
          3. Tell us what it does and what you have tried. “Charges on one port but not the other, tried two cables” gets resolved far faster than “it stopped working”.
          4. Email info@tron-us.com. A photo helps for anything physical — a frayed jacket, a bent pin, a cracked housing.
