It’s happened to most tablet owners: you’re on a vacation and you can’t find your tablet charging cable. “It’s okay,” you think. “I can just plug my USB cord into my laptop and charge it that way.”

Excited, you pull out your USB cord, attach it to your laptop and your tablet, and wait for the charging icon to appear. Tragically, it never does. And you’re forced to watch your tablet die in your arms.

Why does this happen? Well, the USB ports on most laptops do not supply enough power to charge up your iPad or other tablet. Some tablets will even kindly display a “Not Charging” message when connected to an insufficient power supply.

Fortunately, there’s an easy and affordable way for tablet owners to avoid this tragic scenario. Follow the steps below:

Step 1) Buy a travel accessory called the ChargeDr USB Charge Booster, which will go on sale in March 2013 for $29.99.

Step 2) Connect the male end of the connector into your laptop’s USB slot

Step 3) Connect the male end of your tablet’s USB charging cord into the female end of the connector

Step 4) Your tablet will start charging.


How does it work?

If you’re confused about how the ChargeDr works, then you’re probably not alone. Does this bizarre contraption actually boost the power output of a USB port? Or does it do something else?

In addition to apparently improving the power output of your laptop’s USB ports, the ChargeDr promises to charge your favorite electronics up to 4X faster than a regular cable. Tablets are charged 4X faster and smartphones can charge twice as fast. In other words, you can forget about bringing five different charging cables on your next business trip.

The ChargeDr even works when connected to a USB wall adapter, in which case it claims to reduce charging time by up to 20%.

We’re not marketing a product here – this is actually the only way to charge a tablet through a laptop. $29.99 seems like a steep price to pay for a piece of electronics as big as your thumb. But I suppose you can either shell out $29.99 today or not forget your tablet charger next time.
