The power config options are: Charge Current, Power Saving, Shutdown after losing power, ADC Multiplier Override Wait Bluetooth Interval, Mesh Super Deep Sleep Timeout, Super Deep Sleep Interval, Light Sleep Interval and Minimum Wake Interval.  Power config uses an admin message sending a `Config.Power` protobuf.

Power settings are advanced configuration, most users should choose a role under Device Config to manage power for their device.

## Power Config Values

### Charge Current

**Tbeam 1.1 only setting**

Sets the current of the battery charger using the AXP power chip on the Tbeam 1.1

### Power Saving

If set, we are powered from a low-current source (i.e. solar), so even if it looks like we have power flowing in we should try to minimize power consumption as much as possible.

### Shutdown after losing power

Automatically shut down a device after a defined time period if power is lost.

### ADC Multiplier Override
**Fixes issues on Heltec v2**

Ratio of voltage divider for battery pin eg. 3.20 (R1=100k, R2=220k)

Overrides the ADC_MULTIPLIER defined in the firmware device variant file for battery voltage calculation.

Should be set to floating point value between 2 and 4

### Wait Bluetooth Interval

How long wait before turning off BLE in no Bluetooth states

`0` for default of 1 minute

### Mesh Super Deep Sleep Timeout

While in Light Sleep if this value is exceeded we will lower into super deep sleep 

or Super Deep Sleep Interval (default 1 year) or a button press

`0` for default of two hours, MAXUINT for disabled

### Super Deep Sleep Interval 

While in Light Sleep if Mesh Super Deep Sleep Timeout Seconds is exceeded we will lower into super deep sleep or this value (default 1 year) or a button press

`0` for default of one year

### Light Sleep Interval

**ESP32 Only Setting**

In light sleep the CPU is suspended, LoRa radio is on, BLE is off an GPS is on

`0` for default of five minutes

### Minimum Wake Interval

While in light sleep when we receive packets on the LoRa radio we will wake and handle them and stay awake in no Bluetooth mode for this interval

`0` for default of 10 seconds
