Live gauges
- State of charge and real usable energy — not a guess-o-meter
- Pack voltage, current, and power
- Battery, motor, and ambient temperatures
- Tire pressures, all four corners
- 12V system health — the part that actually strands trucks

Your truck's real numbers, at a glance.
Big gauges for state of charge, usable energy, pack power, and temperatures — pulled live from the vehicle, drawn for a dash mount.

What you need
Two things. You already own one.
A Bluetooth OBD-II adapter
A Bluetooth Low Energy OBD-II adapter that plugs into the port under the dash. The Vgate vLinker MC+ is the adapter ChargeState is tested with.
Buying one? Three things to check: it must say BLE / Bluetooth 4.0+ (the cheap “classic Bluetooth” ELM327s can’t talk to iPhones at all, and WiFi adapters aren’t supported); skip anything reporting “v2.1” firmware — that marks the clone chips that choke on the deeper vehicle queries this app relies on; and prefer one with auto-sleep, because the Lightning’s OBD port stays powered when the truck is off, and an adapter that never sleeps slowly drains the 12V battery.
A Ford F-150 Lightning
ChargeState is built specifically for the Lightning's signals — its battery pack, its charging behavior, its quirks. It is not a generic scanner.
Privacy
Your truck's data never leaves your phone.
ChargeState has no accounts, no analytics, and no servers. Every reading, every drive, every charge session is stored on your phone and nowhere else. The app makes exactly one kind of network request: if you choose to send a support message from inside the app, it sends what you typed — and nothing more is ever transmitted, by anyone, for any reason.
The full policy is short enough to actually read: Privacy policy.
