In days of old, lighting equipment in the woods and on the trail was simple. You had a two cell flashlight with D batteries and if you planned ahead, spare batts.

Nowadays, there are lots of options - different, smaller but brighter lights, different battery chemistries, and all sorts of options. It is even more complex with the adoption of the cell phone and other critical electronics. your cell is also your camera, your timepiece, and a whole lot of other useful functions. It is something you want to keep charged while in the back woods.

Time for the power bank, a big batteries whose electrons can be downloaded into the device of your choosing, provided you have planned ahead. Over time, I have acquired quite a few, as I am sure many of us have. they all will replenish my cell phone, and also my headlamps. all that I have encountered sport a flashlight as a secondary function, so I also have backup lighting. One will even work as a hand warmer. The great advantage is that I can allot my spare electrons to either the cell phone or the light, as the situation demands.

One of my faves is a Goal Zero Mini Lighthouse, original version, whih is a very capable general illumination lantern, with replaceable GZ proprietary 3000 Mah rechargeable batteries. Tuck in an extra battery or two, or perhaps a solar panel, and I have as much electricity as I want.

The next step is to include a rechargeable GPS device into the system. I am sure others are exploring the potential in this new and evolving technology. What do you find useful and worthwhile?

Someone who loves me, who also came up with our family motto, "Excisto Paratus", bought me a Big Blue Solar 28 watt foldable solar panel, about $70:

Separately purchased was a battery charger for AAA/AA/C/D/9V cells/batteries with a 12 volt input that plugs into the solar panel. about $20:

For the reason that it will run off standard or rechargeable D Cells, I like the UST 30 day lanterns ($40): https://www.amazon.com/UST-Portable-Life...23327&psc=1

UST also makes lanterns that will run on AA cells.

I also have a couple of the LUCI solar lights, available at Sierra Trading Post and other sources. I just leave them deflated on our south facing window sills, for continuous charging and ready access. I've given them as gifts to our children's families and they have been much appreciated when the power goes out, or for camping: https://mpowerd.com/collections/our-lineup
