 +[[lifestyle:faq_solar_generator|Solar generators]] are a simple although relatively-expensive solution to power storage in cars.  
 +
 +They can be charged from the cigarette outlet or from solar panels, or from wall power while you are at work or in a place where outlet power is available. It may be counterintuitive, but depending on the device's specifications it may actually charge faster using a small inverter to run the wall charger than using the cigarette outlet cord.((it's less efficient to go 12vdc - 120vac - 12vdc but the alternator's huge power output makes the inefficiency a non-issue))

 +People with limited power needs (charge phone, run personal fan) may do fine with a USB power brick (example:  [[https://amzn.to/3f7mI7j|Anker 20,000mAh portable charger]].  Charge from wall power when available or from USB adapter while the car is running.  
  
 +[[https://amzn.to/3vjgR48|Some units also have handwarmer functions]] which may be useful in cold weather.((secessus uses that one)) 
  
 +Power ratings can be a bit confusing;  the 20,000mAh unit above is more plainly understood as 20A @ 5v.((USB voltage is 5v)).  While it may look like a marketing ploy, it is also a historical artifact from when lithium batteries were quite small and 150mAh was easier to parse than something like 0.0150Ah.

 +[[https://amzn.to/3u8o7P7|Jump packs]] are USB power packs on steroids.  They tend to have larger internal capacity and also the ability to produce 12v to help start dead car batteries.  The unit shown here also has a ~60w inverter built in for light loads.
