Speaking of batteries, it is amazing how they have changed over the years. From left to right is a power bank from around the year 2000 to a V Mount battery purchased this year.
The V Mount battery has USB C, so in theory can charge one of the latest Apple MacBook. I don’t have one to see if this is correct but that is what it says on the spec sheet. While the oldest power bank was designed to top up a non smart mobile phone.
Power is one of those things that is easily forgotten when talking about modern technology. The advances aren’t as sexy as mega pixels or processing speed. But without it that new piece of equipment is just an expensive door stop.
