How many USB ports does Omnicharge have?
Along the perimeter there are two 60W USB-C ports (ideal for charging up power hogs like a laptop or a Nintendo Switch), two 45W USB-C ports for less power draw, two full-sized USB-A ports that are QC 3.0 compatible, a full-on wall socket, and a DC in/out port. This spread of functionality is pretty compelling, but there are two additional features that Omnicharge has thrown in. First, there’s the ability to use the ports as a USB 2.0 file transfer hub, doing away with the need to throw a bunch of USB-C dongles in your bag on top of your charger. And arguably the coolest feature is the ability to use the flat side of the brick as a 10W wireless charging pad. The whole unit has a 70h capacity, and that full charge can be achieved in as little as 3 hours using the 45W USB-C input. All of this functionality does come at a cost as this unit will run you around $200, more than double what you’d expect to pay for a more limited, similar-capacity charger. But if the best is what you want, the Omni USB-C+ is a definite contender.

When evaluating a charger, we note its amperage. A charger with a higher amperage of 3.4 or even 4.8 is suitable for charging multiple devices at once.
How fast does a portable charger charge?
Amperage: Often referred to as amps, this is a unit of measure that describes how fast a portable charger can send power to a device.

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. If you’ll be charging one or two devices, get a portable charger with at least 2.4 amps. If you’ll be charging more devices than that, get a 3.4 A or 4.8 A model.

What is the best battery charger?
There really isn't a best overall battery charger, because what's best depends on what needs recharging. The best charger for your phone may be useless if you need to charge a laptop. That said, one brand of battery chargers rose to the top during my testing. Nimble's Champ strikes the best balance between power when I need it, weight, and price. At 6.4 ounces, it's one of the lightest on the market, and you'll hardly notice it in your backpack. It's smaller than a deck of cards and can charge two devices at once, one via USB-C, one via USB-A. I've been using this one for several months and rarely leave home without it. The 10,000-mAh capacity has enough juice to charge an iPad, and it can keep my phone running for almost a week.

Check the specifics of your laptop against the battery you're thinking of buying to make sure they're compatible before you invest.
