planning a road trip and thought of using google navigation continously. so would need a charger plugged in. any one knows of a good charger.
I have read that some chargers are unable to cope with the battery drain caused by the continuous gps use. so need a good rating one.
I am using this one for last 4 years (never tried for a Laptop though). I always use the USB port. Even if I start with 50% charge, with GPS navigation, it will charge my phone to 100% aproximately in 4 hours.
If my entire family needs to charge the phone while travelling, I am keeping an externsion box readily in my car where we plug using our home chargers. It says 200W capacity and it is charging 4 mobiles from AC port + 1 USB port (at-a-time) at good rate. No complains so far and I am happy with it.
I never faced a situation where my phone was depleting faster than the charging rate.
