At last year’s Red Bull Global Rally Cross event some decent swag was handed out by the major sponsors. One of the items we scored was a phone booster battery — not bad!
While cool, the construction of these are on the cheaper side. Like other inexpensive boosters, they lack a button to power up the charge port – they just automatically turn on when plugged into your phone.
Turns out this cost-cutting move is actually a feature: keeping RaceCapture/Pro powered up during pit stops! Just plug it in to RaceCapture/Pro’s USB port, and when 12v power is cut, it’ll seamlessly provide power for an extended period of time. The unit we scored was rated 2200mAh, which is good for about 2 hours of continuous use. Since these turn on/off automatically, they’ll simply go idle when 12v is turned back on.
What’s the benefit of keeping telemetry active during the pit stop?
- Maintain GPS lock
- Watching sensors while engine is off (is the coolant temperature spiking due to lack of flow?)
- Maintaining a constant cellular link
