Here’s a tip. There is a way to share the Jamboree with your smartphone and have it fully charged and available every day.
This advice assumes that most youth participants will likely use a smartphone to take pictures and video during the jamboree. Jamboree planners assume this as well and have incorporated recharge stations located at each of the base camps.
Recharging however takes several hours and you would like to use the device during the daytime. Recharging a phone overnight in the tent offers the most convenience.
Here’s a way you can have access to your phone in the daytime and recharge it in your tent at night. It incorporates the use of a rechargeable USB recharger.
It’s a rechargeable battery that supplies a built-in USB port with the 5 volts of power needed to allow a smartphone to plug in and recharge. The recharger battery itself requires a 110 V line to recharge later.
The workflow of the use of the battery is shown below. After an overnight recharge cycle in your tent, drop off the USB rechargeable recharger battery to a recharge station located inside each base camp headquarters. Bring it’s 110V adapter to plug it in. Have fun and use your phone to take pictures and video. Pick up the recharged USB charger battery and it’s adapter on your way back to your campsite.
I would recommend a capacity twice that rated for your smartphone.
For example the iPhone 5 has a 3.8V, 5.45 Wh battery that should offer 1440 mAH of capacity. A 2880 mAH or more USB Rechargeable battery rating should have enough capacity to fully recharge a fully depleted phone battery.
Why is a higher capacity recharge battery needed. Recharging using batteries solely is not a one to one transfer of energy. All batteries give off heat during recharging. This means a recharger must be able to supply more than the rated capacity of the battery undergoing a recharge. A rating double your smartphones battery rating acts as recharge insurance to insure a full recharge. It also helps to insure against the gradual capacity reduction that develops over time with rechargeable batteries.
A quick review of retail pricing shows many USB rechargeable chargers exist with 2500 mAH or greater capacities between $28 to $50.
