Best portable battery charger on sale

You really find out how little battery your portable devices have when you head to a conference. Between increased use taking notes, texting friends, and getting directions, you'll find your devices dying half-way through the day. For these occasions, we recommend a portable batter charger. The one that both Paul and Michael use is on sale today for only $20 on Amazon with the code FK9SLMB8. I bought mine for $40.
