How to Build Your Own Smartphone Battery Backup

How to Build Your Own Smartphone Battery BackupThis is an interesting project for those do-it-yourself people who like to tinker. It seems that all of us have become victims of buying everything already made and we no longer get our hands dirty to either built a PC, or in this case, to build a smartphone battery backup. Let me just say this: if you have never built yourself a desktop PC, you don’t know what you are missing. I have built hundreds of computers for myself, my family, and for clients, which has always left me with a feeling of satisfaction when the job was completed.

Similarly, building your own smartphone battery backup system is a project that you can do for yourself or share with another family member. I would classify the knowledge needed to complete this project as moderately easy, but your tech expertise will decide just how easy — or difficult — the project will be.

First, let’s start with some of the parts you will need to begin.

The battery is the heart of a smartphone battery backup system. One would think that a car battery could serve as a battery backup, but this is not the case; car batteries expel gases during the charging process, and no one wants that inside of their homes. One battery I’d recommend is one that is designed to be used in a marine environment, produces no deadly gases, and is leak proof. One such battery for use in a battery backup system is sold at Amazon and is called the Optima 8014-045-FFP YellowTop Group 34/78 Deep Cycle Battery. The battery sells for about $185.

A wall charger is needed that will keep the battery fully charged and is compatible with a marine type battery. Amazon has such a charger and it is priced at $25. Schumacher SC-600A SpeedCharge High Frequency Battery Charger.

To complete our project, we will also need a battery clip-on cigarette lighter adapter that connects to the battery. The Roadpro 12V Battery Clip-On and Cigarette Lighter Adapter at only $5 meets this need.

Finally, you will need to purchase a USB car charger like this one: Griffin Powerjolt Dual Universal USB Micro (priced at $5), plus a volt meter of some type to measure the power remaining in your battery; the Equus 3721 Battery and Charging System Monitor meets this need at $15.

Once you have the parts all rounded up, just follow these directions to set up your charging system.

  • The first thing you have to do is connect the wall charger to the battery. Make sure you use the correct connections, which are marked on the battery pole. Red to plus and black to minus. Let the system charge for six to eight hours.
  • Once the battery is fully charged, it is now time to check to see if your phone can be charged. Attach the cigarette lighter adapter to the battery with the same connections (red to plus and black to minus) as above.
  • Plug in your USB cable to the phone adapter and you should see the charging indicator on your phone pop into action.

The amount of times you can charge your phone will depend on how much power your phone uses during normal operation. However, using this type of battery backup will provide more charging power than the simple backups that may charge a smartphone as few as three times.

How do you keep your smartphone working when the power is out?
