  • Start by defining your available power. How many watt-hours can you generate? A small 100W solar panel can provide an average of 400Wh of energy per day in the winter. That’s more than enough to run a 10-inch tablet 24/7 and LED lighting at night. I’ve seen 360W solar panels for under $100 on the used market. That’s a couple of KWh a day. Even a 100W bicycle generator and a 30 minute workout would power a tablet for 8 hours.

    If power consumption is that big of a factor, perhaps separate devices for video, music, and reading would be beneficial. A dedicated music player can consume less than a watt. An e-paper reader requires fractions of a watt.

    I have a folding 100W panel, a 30Ah 12V LiFePO4 battery, and a charge controller that I use while car camping. It keeps all the electronics running for a group of 4 without relying on a noisy generator. The battery is big enough to compensate for a couple of rainy days.

    My backpacking setup is a 15W panel and a 30Wh battery. That kept my phone and flashlight charged for 2 weeks on the Pacific Crest Trail.




  • There are plenty of companies that will sell your name, email addresses, phone numbers, street addresses, marital status, and relative’s names. They obtain the information from publicly sold databases. I had access to one that had all that, plus the registration info for the car I drive, my estimated income, my military record, my driving record, my political party preference, and pictures of my home that had been on the realtor’s website.

    The scary one was when a phone center employee in the Philippines stole my wife’s debit card number and then did two big Western Union MoneyGram transfers to a couple of Filipino men. That means bad actors have access to the credit companies’ databases from which Western Union draws their proof of identity questions, like who holds your mortgage, where you lived when you were 10, and the make/model of your first vehicle.

    If you’re well-off enough to be a financial fraud target, paying a company for identity theft protection is probably well worth it. Put fraud alerts in with all the major credit bureaus too. That usually stops identity thieves from accessing your credit. If you use 2FA with your phone, make sure your telecom provider will not transfer your number to a new device without in-person authorization and authentication.
