So this fall I will be traveling to Alaska, I know cell coverage up there is available but not always the most reliable even in the populated areas so I will be taking at least one set of radios up there with me for the trip.
At the moment I am considering taking 2 Motorola UHF HT750’s. They are the best suited for the environment of the units currently available to me. The downside is having to charge the batteries. I know the standard rapid charger requires an 18 volt input to charge these units so I am considering either buying or building a portable power source to have as a backup should I need to charge these in the field or provide power for phones / tablets.
So the way I see it there is a few options. Either I get a 12 volt rig that I can then plug a car 12v to AC adapter into or I custom build something that has the ability to output different voltages.
Going the 12v method means I loose a lot of energy going from one medium (12v dc to 120v AC back to 18v dc) and may need a larger battery to be worth it. But custom making the battery/charging station would take more time and perhaps money, but may result in the best size/least amount of equipment.
Any one have any thoughts or taken on a project like this?
