A central air conditioner is great for keeping your home comfortable, but sometimes the added cost or space requirements needed for one aren't ideal.

Window air conditioners or portable air conditioners are perfect to counter this situation -- the latter more so -- because of the minimal space it needs. Plus, a portable AC unit will keep your space comfortable for less money and hassle. To provide more context, like window air conditioners , a portable AC is placed right in the space you want to cool down without the need for any ductwork.

Now, they have to be vented through a window -- don't forget to take this into account -- but the best portable AC comes with wheels, making it easier to move around. Whether you're looking for a portable air conditioner for an apartment, a particularly stuffy part of your home or another space, we've tested several portable AC units in the CNET Testing Lab to see which can get your room cooler and maintain its air conditioning. But if you're looking for a straightforward answer, our newest pick, the Black+Decker BPP08WTB , is the best portable AC unit that does this on a budget.
