Do you like balloons? Well, it doesn't take you to like them just to know that you need air to make them big and round. That's common sense. That would also go for 'inflatables' like boats. You have to make them portable and, with their size, you cannot make them that if you cannot have them occupy less space when not needed.
If blowing into these things with our mouths is that simple, then we would be all doing that instead of looking for something else to make air. Just imagine how much air will your lungs have to produce before it fills up one balloon, let alone an entire boat!
That's why we have inflators, like this Metro Magic Air 110V Inflator/Deflator from Metro Data-Vac. As you can probably see, Metro Data-Vac is not a producer of fine vacuum cleaners alone but of other handheld machineries as well. This handheld gadget is all made from steel. This means it's durable and mostly weather-resistant. Weighing only three pounds, this device can be carried around anywhere where there is a socket. The only problem I could think of is that you don't normally bring a socket with you when you're outdoors! But bringing a generator with you will solve that.
One more thing that I like about this product is that it is not only an inflator, but a deflator as well, making it a double gadget. Gone are the days when you have to wait for quite a while until your inflatable loses all the air it contains.
With the Metro Data-Vac Inflator and Deflator, you're ready to get into more boats and send away more balloons.
