Does anyone have any experience with Portable Power Sources? Looking at dropping about $500 bucks on a small unit + a fold-up, portable solar panel to recharge on the go. Reason I’m looking now is that I have a sleeper trip coming up on LOTW with my two boys and devices will need to be recharged. however I think this would be great for throwing the Strikemaster 24V battery between drilling while ice fishing. Also good for camping and just emergency back-up for bare essentials if we ever had a lengthy power outage, etc.

I’m in the process of putting together a solar system for my off the grid hunting property, so I’ve studied this a lot.
The problem with solar is the amount of available daylight you have in the winter. The wattage output ratings of these devices are listed under ideal conditions, which you will never have. To keep even a single deep cycle battery charged in January, you would have to a huge solar panel because your efficiency is cut way back by sun angle, duration of sunlight, and the number of cloudy days.
For your needs, a better investment would be just a quality pure sine wave (PSW) power inverter and run it off your vehicle battery or bring one of the deep cycle batteries from your boat.
– Phones and devices – Takes almost nothing to charge these. First off, most car charging cords are junk. Buy high-quality USB chargers that are rated at 5 ahr charging. This will charge tablets and phones is half the time or less that it takes with the el cheapo cords.
– Cordless auger/tool batteries. For over 10 years, I’ve been charging Milwaukee batteries with a small power inverter in my vehicle. Many newer chargers won’t work with the cheap modified sine wave inverters, so buy a good pure sine wave unit right out of the gate.
An inverter also is handy because then you run all your device chargers from home rather than having to let devices sit in the vehicle to charge off of DC. It’s also tremendously handy for other stuff, I’ve run trouble lights off of mine, I’ve run my chainsaw sharpener, Mrs. Grouse uses it on long trips to chage her laptop, etc, etc.
As always, if using your vehicle battery, have a backup battery and run your vehicle every day to make sure your starting battery stays topped up. Inverters use power even when not under load, so don’t leave the inverter on when it’s not needed.
