Back in the 1970's I got tired of the hassles of trying to use mantle lanterns and decided to try using electric lighting in the tent...
This required a battery and inverter (since 12 volt bulbs and fluorescent lamps proved less than optimum).
After much experimenting, I finally settled on a small 12 volt storage battery and inverter along with a 120 volt LED bulb in a pendant (hanging) fixture for intent lighting.
Here is my most recent tent battery and inverter combination;
Its a 12 volt 50 amp hour LiFePo4 (lithium iron phosphate) battery, weighing about 11 pounds with a modified 80 watt (added a switch and terminals) inverter and custom carry handle.
It recharges USB toys and can power most of my 120 volt toys (one at a time).
When I was backpacking I experimented with USB power packs/banks but they are a bit on the small side for my needs.
I don't normally bother with solar charging or a generator as this provides energy enough for my purposes during week long camping trips.
I recharge it at home before each trip using a 10 amp "Genius brand" battery charger. I do have a 12 volt to 12 volt charger for charging in the field, which, so far, has not been needed.
Since the rules are just one hack, I will cover the tent light tomorrow, and other toys/items in subsequent posts..
If you get the impression of "Glamping"; you are correct; I gave up bare bones sometime around the beginning of this century...
Simple can be good but it can be less than comfortable.
As long as everything will fit in a 2 door Jeep (CJ, YJ, TJ), its all good!
