Portable Power

Portable Power

For most of us, having access to electrical power has become so second nature that we hardly give it a thought. It's so abundant to be almost free, and there are lots of places all around to plug in your cell phone when it runs out of juice. But if the grid goes down for a long period of time, or you need to charge your devices on the move, then you need to consider sources of portable power. It makes sure you can recharge your child's tablet so they can watch their favorite shows, and hopefully be distracted to a less than ideal situation around them. It keeps your communication devices going, and keeps your lights working at night.

This list factors in only small devices, such as anything charged over USB like phones and tablets, or anything that runs off AA or AAA batteries like head lamps.

Ni-MH AA and AAA Batteries

There are several different types of rechargeable batteries: from the lead-acid which powers your car or truck, to Ni-MH which are used in AA and AAA batteries, to Lithium-Ion used in portable re-chargeable electronics like cell phones. Lets look at Ni-MH which stands for Nickle Metal Hydride.

Eneloop Batteries

Panasonic eneloop AA batteries

Price: $40
We have been using eneloop batteries for years. They are considered by many insiders to be the best-made rechargeables. They maintain 70% of their charge after 5 years of storage and they can be charged and discharged up to 2100 times. Unlike the older rechargeable AA and AAA there is no memory effect on them, you don't have to fully charge and discharge to maintain them. They pay for themselves after using them only 5 times. We have them in our head lamps, torches, and table lamps.
