I’ve stumbled across some tech that I can’t live without. In a world of consumer goods with USB rechargeable batteries and in that same world when we are constantly on the go it’s tough to keep up with charging phones, and cameras, and tablets, and radios.
Also, I like to camp and my camper doesn’t have any USB charging outlets. If you tent camp or do boondock camping then wouldn’t it be nice to have portable power to get you through a night or two? A light to read by? Or power for your phone or GPS? Do you work in the field and need to recharge batteries such a camera batteries. I work on airport Visual Landing Aids which require precise glide slopes and I can’t tell you how many times that the surveyors have shown up and left because their batteries were dead and they had to go back and charge them.
If the power goes out at home your generator might not supply a clean sine wave which means your sensitive electronic devices could get damaged. Clean power can be supplied from an Inverter, Inverter generator, or Inverter power station.
Or, how about this? There isn’t an available USB port for charging because you have too much other stuff plugged in. Perfect for a stop gap measure.
