I'm an engineer, and tend to try to look at the worst reasonable case. Sparke is likely correct, but I'd like to give a worst case sort of opinion.
Sparke is exactly correct on computer and radio energy useage. My laptop draws 45W maximum. The car has 60,000 kWh. So, ignoring losses, I could charge the laptop for a few months, at 24 hours per days and maximum usage. Radio is even less. No worries here.
The "No Worries Range" is a little less than half of the EPA range. You can drive the car the NWR when the car's battery is almost due to be replaced under warranty, on a cold day with sloppy roads. The NWR of the Bolt is about 100 miles. 150 miles per day is beyond that. So you might have worries, on cold days when the car's battery is getting close to being worn out. Are you OK with that?
The warranty limit on the battery is a 40% loss over 100k miles and 8 years. A 40% loss reduces your range from 240 EPA miles to 144 miles. Yes, lower speeds will help some, but cold weather, with snow/slush on the roads will hurt more. On a really really bad day, with the battery down 40%, you might make only 100 miles. Now in your climate, battery loss isn't likely to be that much, but it still could happen.
Sure, by finding and using public charging on bad days you can stretch out beyond the NWR, but public charging is scarce, often poorly placed, often expensive per kWh, often busy and sometimes broken. Relying on it isn't something I'd suggest.
Do you have 150 miles days in the winter when the roads are slushy?

Most everything around here is wet during the rainy season. And the rainy season is long.

Can't sit in a Bolt seat, hoping for better soon.
Or perhaps a Buick version? Buick Electra 225???
