I'm on week 5 of a multi-year camping trip in North America. I'm able to make this trip because I do freelance writing work from the laptop, which can be done anywhere with an internet connection, and in many cases, places without. My base of operations is a 1993 4runner, and I'm running into some issues with electricity storage, generation, and transfer. Electricity generation comes from the 4runner alternator. Storage is presently just the car battery and all the batteries in the various devices I have (and depend on).
What I'm thinking is that I have so many 5V devices that I should install a dedicated ~12V DC - 5V DC converter that has nice smooth regulated output and can push 10ish amps. Here's what I'm trying to power off 5V:
- dashcam ( ~0.5-1 A )
- Samsung Galaxy S7 ( 2-2.5 A )
- old phone for music ( 1.5 A )
- Garmin vista hcx GPS ( ? maybe 1 A )
- a few misc items - goalzero light / battery, 12000 mAh ravpower battery pack
So the question is: How best do I rig up a 5 V power supply to power all of this? I've spent a few hours researching peoples' tangential approaches and haven't really figured out the best solution in my case. I need to figure out fusing from the safety/fire side as well as the protecting my devices side, I want to if possible and not prohibitively expensive install a meter that shows battery current state and how much power each device is pulling, I want to mount all of this so there's not a mess of wires everywhere, and finally I want to install a wireless charging thing for my fancy new phone (what's the point of having a fancy new phone if you can't take advantage of fancy wireless charging?).
Any imput that anyone has is much appreciated. I've been out in the cut without cell / internet signal for 10 of the past 12 days, and so internet access is temporally a valuable commodity for me. Thanks for any help you can render! I'll share some photos of the trip if anyone's interested.
