The Best Smartphone and Tablet Chargers Of 2012

Today, we use smartphones and tablet computers wherever we go. However, batteries life tends to be a constant issue. That’s why carrying a spare charger in your daypack or purse makes a lot of sense. In most cases, you just need a bit of spare power to make a call or access the internet.

Smartphone (USB) chargers all contain a rechargeable lithium-ion battery, and a USB socket that outputs 5 volts. The difference is the power capacity of the batteries inside the chargers, and this capacity is measured in milliamp hours (mAh). Here’s a quick guide to what you can charge with different battery capacities:

  • 1000 – 5000 mAh: This is enough power to recharge a smartphone or small USB device
  • 5000 – 12000 mAh: Enough power to recharge a phone, iPad or other tablet computer
  • 12000 mAh +: Enough power to charge a notebook computer, tablet computer, or smartphone

These are our selections for the top rated smartphone and tablet chargers:
