What are the best portable car air pumps?
The best 12V portable air compressors are those that do not plug into your cigarette lighter, but instead, require you to attach a pair of battery clamps directly to the battery. Why? Because the power of the compressor is limited by the current that can be delivered through the cigarette lighter.
Why do you need more power? Convenience, mostly. In the grand scheme of things it doesn’t matter whether it takes 4 minutes or 10 (yes, all these small pumps are slow) to air up your tire — but when you’re standing on the side of the road waiting for it — you’ll be convinced it’s a piece of crap and that you would be happy with a better one.
This difference matters as the size of the tires increase. It only takes the 12V pump a minute to fill the tire on my motorcycle — but the big mud tires on my truck take forever!
The other feature I highly recommend is one that automatically shuts off when it reaches the desired inflation pressure. This will save you from feeling like it’s essential for you to stand there and monitor the progress, or checking it fifteen times before it’s full.
