2: Portable Gas Pump
The days of carrying a heavy gas can around are gone, and now you can get a portable gas pump for half the price. The portable gas pump is a unique device that can pump up to ten gallons of gas without you having to lift a finger. The design is a miniature gas pump, and it has some pretty unique features (via McCarthy Auto Group).

If you’ve ever wanted to pump gas, but you didn’t want to deal with a heavy gas can, then this is a great option. Although the price is high, you can’t put a price on convenience, and this is about as convenient as you can get.
