If you are searching for a portable miniature refridgerator with or without built-in USB, you have some great options to choose from these days.  Although some gadgets that people buy lose their appeal after awhile, portable fridges are an amazing invention that offer a lot of practical value for many different types of people and occasions. Porta-coolers are just like taking a tiny refridgerator with you everywhere you go. Here are just a few of the great ways that these appliances come in handy:

Traveling With A Medical Condition - Imagine being an insulin-dependant long-distance truck driver, or someone having to drive hundreds of miles with medication that has to be refridgerated. It can be a matter of life or death when it comes to the proper storage of certain medications while on the road.Cooluli Mini Fridge in pinkCredit: Courtesy of Amazon.com

Work Site Comfort - Many work sites and construction locations are located well off the beaten path. On hot summer days, staying hydrated is important. It can be nice to know you have access to cool drinks for your entire shift without the hassle of ice meltdown.

Party Time Social Events - Camping and beer, tailgate parties and more. If you like to camp away from the campground ice machines, your vehicle cigarette lighter is the only outlet you need to plug in a cooler and keep those cans cold.

Outings Where Finding Ice Is A Long Shot - Boating is another hobby where a portable mini-fridge can come in handy. It doesn't take long for those ice-filled styrofoam containers to turn into a melted mess on a hot summer day. I have experienced many a lake outing where my ice-filled cooler filled with cold sodas became a warm swimming pool for my lukewarm cans. Yuck!

 

Koolatron P65 Kargo 12v Portable Cooler

The Kargo by Koolatron is a really versatile product. It plugs right in to your car's 12V cigarette lighter and gives you enough space for up to 42 12-ounce cans. I like the fact that it has a split-level design. You can use it as a top-loaded fridge for your food and drinks, or you can flip it vertically so it opens and operates like your home appliance.

Has a switch that turns it into a warmer for baby food and bottles.

Giantex Portable AC DC Mini Fridge

This little miniature fridge is adorable. It reminds me of a mailbox. The tiny features make it perfect for tight spaces. It would be awesome sitting on a desk corner or file cabinet at work because it doesn't take up much room. Other than the red exterior, what makes this cooler unique is the simplicity of it. No bells and whistles, just a place to store up to 6 16-ounce cans or 4-6 bottles of water. There is enough space for a small piece of fruit or a snack. It operates on both AC or DC power supply.

Cute little budget model for tight spaces

Gourmia GMF600 Portable 6 Can Mini Fridge

Is it a toaster? A bread maker machine? It's the smoothly rounded Gormia 600 series portable. You can use this both at home with  AC/ DC power sources or into an auto lighter on the road. The manufacturer has designed this with a removable interior shelf so you can make room for tall items if you want to. It holds up to 6 12-ounce cans or 4 500ml bottles of water. The fridge handle locks to prevent thieves or "borrowers" from helping themselves to the contents.

 

Available in 3 colors: white, blue or red.

Gourmia GMF-900 Portable 9 Can Mini Fridge

The Gormia 900 series is much like the smaller version above, but holds more. The manufacturer also makes an even larger model that holds 12 cans. This product also comes with a self-locking door handle; a measure of security when you are on the road making turns and going over bumps. The 900 model only comes in white.

Quiet enough to sit on your desk at work without disturbing your coworkers

Cooluli Portable Refridgerators Have Carry Handles

This has to be my very favorite brand  because the manufacturer has added a little decorative personality to their products. I would have a hard time choosing between the pink or the cow print; both are super-cute. They have a magnetic self-locking door. I love the fact that this model has a carry handle. The color selection makes it a good option for a baby nursery. It's surprising how many new mothers are using portable mini coolers in the nursery.

Comes in white, pink, fuschia, blue & cow print.

Portable Mini Fridge Appliances Are Perfect For Students

Not a bad idea for a man cave either

Because of their compact size, these gadgets are perfect for college students who have to live in tiny dorm rooms. They give you a personal place to store a few drinks and snacks. They also make a great "lazy day" gadget for people who want to sit in their favorite recliner, watch the game, and not have to get up and go to the kitchen refridgerator to grab another drink.

I think teenagers would have a blast with a porta-cooler; especially if they have a basement "party" room and the notion that they are too cool to trudge up the stairs for another soda.
