Tech Gift Ideas for Dads & Grads

This is a sponsored post written by me on behalf of Cobra. All opinions are 100% mine.

I’m not the best driver in the world, but I’m also not the worst. I’m okay with calling myself an average driver with average needs.

I stick to the posted speed limit, I yield to pedestrians, and I stay within the lines (not just in driving, but in coloring books as well).

There are certain features I wish my car carried with it – not the least of which is a warning light that would illuminate whenever I was about to obey the law and incite a fellow driver’s road rage. They’re probably working on that in a lab indirectly somewhere right now (along with edible turn signals since drivers don’t seem to use them for anything else).

Heading out with the family? Heading back to school? Dads (and grads) could use better tools to further enhance our driving experiences, but we’re not necessarily the kind who will pull over and ask for directions. Sometimes, you have to gift us with technology before we will accept it into our lives.

I was sent an Escort Max 360 radar detector, and my immediate thought was: “I’ve never felt like I needed one before, so how will this tool actually help me as a driving dad?” Then I saw the “Posted Speed Limit Data” feature and got very excited. Yes, this device knows the posted speed limit in your location and will warn you (unlike your car) when you’re going over.

I’ve wanted something like that for the longest time, and I can’t tell you (as someone who respects the law) how genuinely excited I was to see this. Yes, it’s a system with dual front & rear detection, arrow indicators to point out the source of a radar, GPS-powered for rejecting false alerts, and lightning-fast data detection – but all of that intelligence means nothing if you’re playing fast and loose with the rules.

Yes, I’m a stickler – but that’s what keeps me (and others) safe on the road.

I also like planning ahead, so my trunk has a tiny kit with all sorts of emergency accessories in it. As soon as I saw the Cobra JumPack – Tiny but Mighty, I knew it would be a permanent part of my prevention pack. With it, you can not just rapid-charge your favorite mobile devices, but actually jump start your car multiple times (on a single JumPack charge). And it has a little LED flashlight built-in!

Okay, the smallest things often get me the most excited. Does your portable battery pack have an LED flashlight built-in? Didn’t think so. Oh, and it also comes with jumper cables – without any worry about needing another vehicle to help you start moving again.

You don’t need to wait for a specific occasion to gift a dad or grad the right tech tools – they may not know that these experiences exist, so why wait another day to enable them to become a better-prepared driver?

I wouldn’t recommend waiting too much longer – because they probably needed these tech tools last week at some point.

Car Batteries: Acid-Lead vs. Lithium Ion

Add to iTunes | Add to YouTube | Add to Google | RSS Feed

Bob Lutz, GM Vice Chairman of Global Product Development, recently discussed different types of batteries and the forecast for each during a round table interview. Which is better? What is more cost-efficient? Let’s start by defining the two types of batteries in question.

Lithium Ion batteries are a type of rechargeable battery in which a lithium ion moves between the anode and cathode. The lithium ion moves from the anode to the cathode during discharge and from the cathode to the anode when charging. Lithium ion batteries are commonly used in consumer electronics

Lead-Acid batteries are the oldest type of rechargeable battery. Despite having the second lowest energy-to-weight ratio and a correspondingly low energy-to-volume ratio, their ability to supply high surge currents means that the cells maintain a relatively large power-to-weight ratio. These features, along with their low cost, make them attractive for use in cars, to provide the high current required by automobile starter motors.

Bob stated that 18 months ago when GM announced the new Volt, there were many nay-sayers. Those people said that GM were crazy, and said that using Lithium Ion would never work. Yet, these same people and companies have announced that they are now working on the very same things.

All the technology for the car is here today, except for the battery pack. It will use lithium-ion (li-ion) technology. Current hybrids use nickel-metal hydride (NiMh), which carry much less energy per unit weight. The li-ion cell technology exists but putting it into tested and safe packs is what will take some time. There are companies working with GM and trying to get these Li-ion batteries and their packs ready for automotive use.

As the technology proliferates across the industry, the price will come down. How many labor hours do you think goes into making just one of these kinds of batteries? I bet you’re surprised to find out that the entire process is so automated, it only take four minutes’ worth of ‘man labor’ in order to create each one.
