If you’ll be charging one or two devices, get a portable charger with at least 2.4 amps. Keep in mind that with amperage, performance is affected by the total number of devices being charged, so if you buy a 2.4 A portable charger and connect two devices, both will charge more slowly than they would if charged individually one after the other. For example, a 1.0 A portable charger will take a few hours to charge a phone, while a 2.4 A portable charger can do the same in under an hour. Capacity is the single most important feature of a portable charger, so pay attention to the mAh numbers as you compare models.Īmperage: Often referred to as amps, this is a unit of measure that describes how fast a portable charger can send power to a device. Smartphone batteries usually have a capacity of between 2,500 mAh and 3,500 mAh. For example, a fully charged laptop battery typically stores around 5,000 mAh. Milliampere hours: These are the units of measure for battery capacity. The most important tech specsĭifferent portable chargers offer a lot of different extra features, but at the end of the day, there are only two specs to care about: the milliampere hours (mAh) and the amperage (A). They’re a little more expensive, but they usually include a pretty big battery, so the investment is worth it. But if you need to charge a beefier device like a laptop, you’ll need to buy a portable charger with an AC outlet. If you’ll mostly be connecting devices that can charge via USB, just about any portable charger will work. Do your devices charge via USB or with an AC adapter? If you expect that you’ll need to recharge a lot of gear regularly, buy a portable charger that supports charging multiple devices at once.
