I currently have the Garmin Overlander GPS in my truck. I was considering getting an InReach Mini and pair it to the Overlander for vehicle use. I've read many reviews complaining about poor satellite performance of the InReach Mini. I've also read this may be due to the device trying to conserve battery power by regulating when the receiver is active. Would performance be improved if connected to a constant external power source in my vehicle? Would this allow the GPS radio to stay on continuously? If so, seems like using a small USB power bank would work the same way for hiking use.
