Best phone carger for moterbike?

[Quackerzakieee]

Hi all just looking for some opinions on what the best phone chargers are about

I'm guessing a USB socket is all you'd really need?

I have a four day trip coming up so to run the phone for satnav I'm just using a powerpack. Saves adding yet more wiring to the bike and I don't really need a 12v socket on either of the bikes that way.

If you are thinking of using your phone as a navigation device you will need a charger of at least 2.1 amps to keep the phone charged.

Is it for satnav? or just charging?

Is phone waterproof? do you have compartment for phone on bike or tank bag or under seat?

I just have a double USB socket tucked away under the pillion seat and the charger lead is routed to the tank bag via the underside of the riders seat so it's all mainly hidden
