Solar & batteries ...
The house battery in our Livin Lite truck camper has died after about 3.5 years of frequent use. Lots of boondocking during which it kept the fridge, LED lights, water pump, ... running for about 3-4...

1) iPad = 3A x 4 hours of charging or use daily = 12AH
2) Cell phone = 1.5A x 4 = 6AH
3) Laptop = 16A x 4 = 64AH
4) Dometic 3-way fridge running on propane = 3.5A x 24 = 84AH
5) RV water pump = 7.5A x 0.3 = 2.25AH
6) RV furnace = 12A x 3 = 12A x 3 = 36AH
7) LED lights = 10A x 4 = 40AH
8) Camera = 4A x 4 = 16AH
9) RV radio = 4A x 2 = 8AH
10) Shaver = .67A x .3 = .2AH
11) Gas detector = 1A x 24 = 24AH
12) Inverter = .5A x 24 = 12AH

Most of these estimates are WAY WAY off.
1. ipad will run for hours and hours on a 4 AH battery
2. cell phone runs all day on 2 AH
3. laptop will run for hours on 4 AH
4. Cannot provide any info. I run a full compressor refrigerator on about 30 to 50 AH.
5. My water pump pulls about 3 amp and runs maybe 10 minutes a day.
6. RV furnace mine pulls 5 amps and I rarely use it more than a few minutes a day.
7. LED lights. I usually run about 1 amp of lighting. If I turn on lots of lights I might hit 2 amps.
8. camera?? I charge my DSLR batteries daily for way less than 1 AH.
9. RV radio most radios will be closer to 1 or 2 amps.
10. Shaver. don't own one. don't know.
11. Propane detector pulls about 1.5 AH per day.
12. Inverter...inverters waste at least 10% of the power provided. I try to stick with 12 volt appliances and rarely use anything but a very small inverter.
Not counting the shaver and refrigerator, I typically run all my devices for less than 20 AH per day. That includes a lot of laptop time and topping off the charge on several camera batteries.
