A solar cell phone charger could definitely be viewed as a worthwhile addition to your preps. Especially when you consider how affordable they are. Solar panels for your home are quite an investment, but a solar cell phone charger will cost you about the amount of dinner for two at a fast food restaurant. That’s around $20 nowadays, which is a lot more than it used to be!
While there is the potential that cell service will be down, there is a very plausible chance that it won’t, and even if it does go down at some point service will resume and having a way to contact others will be very important. Most people won’t have this option 48 hours after things go haywire because their battery will die and they will have no means to recharge it.
As much as we might not like receiving them, messages will be sent to every cell phone from the government updating us on conditions. These can potentially inform us of status of the power grid, food lines and first aid care if needed. I wouldn’t worry about authorities being able to track you from the location of your cell phone. Things will be so haywire and so overwhelming for them, that the thought that they don’t want you trying to survive in the woods is beyond ridiculous. They aren’t going to track every prepper down to put you in a camp. Anyone who thinks that doesn’t have a good comprehension of what the SHTF will be like.
You might find that when your cell phone is charged and you send out texts or try to call people that very few are able to respond. When you are trying to reach a loved one, or your ex who has your kids with them or anyone important in your life, having the ability to connect with them is invaluable. Considering the affordable cost of a solar cell phone charger, I would buy several to give to those people who are most important to you so that you can be in contact with each other during this unpredictable time.
