Off Stamp Charger
Standard USB-C — meaning any phone-grade cable you already own works. Here's the cable that ships with the kit, what counts as a safe replacement, and what to avoid.
What ships in the box
Every Off Stamp X Cube Kit (both 25K and Crystal 35K) ships with a short USB-C cable — roughly 8 inches, USB-A on one end, USB-C on the device end. The cable is rated for 1A+ and works with any standard USB-A wall adapter (phone-grade).
Cable specs (what you need in a replacement)
| Spec | Requirement |
|---|---|
| Connector (device end) | USB-C, standard 24-pin. |
| Connector (power end) | USB-A is fine; USB-C-to-USB-C also works with a USB-C wall adapter. |
| Current rating | 1A or higher. |
| Cable length | Any standard length. The included 8-inch cable is convenient for travel. |
| Data lines | Not required (the Cube device only consumes power). "Charge-only" cables work. |
What to avoid
- Unbranded fast chargers above 2A. The Cube device's internal controller caps charging current at roughly 1A regardless of what the adapter supplies — but cheap adapters can have voltage spikes that damage the cell. Stick to brand-name phone chargers.
- Knockoff cables with unstable resistance. A bad cable shows up as on-and-off LED behavior during charging. If your device flashes intermittently while plugged in, swap the cable first.
- Wireless chargers, magnetic pucks. The Cube device has no inductive coil; only the USB-C port works.
If the device won't charge
Most "won't charge" reports trace to one of three causes:
- Cable seated wrong. Off Stamp's USB-C port is recessed; the connector needs to push in firmly until you feel it click. Pull it out and re-insert.
- Dead adapter. Try a different USB port (computer, different wall adapter, car USB).
- Over-discharge protection. If the device hasn't been used for many weeks while the battery was low, it may enter a protected state. Leave it plugged in for 15+ minutes; the LED should re-engage. If after 30 minutes the LED is still off, email service@offstampvapeusa.com with your order number.
Need a fresh cable?
We don't sell replacement cables direct — any standard USB-C cable from a phone-accessory aisle works (Apple, Anker, Belkin, Amazon Basics all do). Phone-grade is fine; you do not need a "fast charging" or "USB 3.2 Gen 2" cable.
