Our Verdict
While the Ace by RAVPower couldn't claim the top spot, it distinguishes itself from the rest of the batteries that we tested by having an unmatched capacity. This portable battery pack can charge typical smartphones 4 or 5 times or smaller tablets 2 or 3 times, ensuring that you are never caught with a dead battery with any of your devices. While this battery pack is a bit heavy and bulky to carry around in a pocket, it easily fits in a bag or backpack. It's a bit more expensive than some of the smaller batteries, but it's the best option if you are heading off the grid for a few days and want to make sure you don't run out of juice, earning it the Top Pick for Maximum Capacity award.
Our Analysis and Test Results
This portable battery pack finished right behind the Anker PowerCore Speed 20000 and ahead of the Tzumi Endurance AC 12000. The RAVPower Ace 22000 is just a bit less portable than the Anker PowerCore Speed, but performed a bit better in our capacity tests. It is about equally convenient to use as the Anker PowerCore Speed and takes about the same amount of time to recharge. However, the RAVPower costs quite a bit less. The Tzumi costs quite a bit less than the RAVPower and is a bit easier to fit in a pocket, but has less capacity and takes forever to recharge.
Even the largest batteries are quite easy to carry in a bag or backpack.

Portability
This high capacity battery is at a severe disadvantage to the smaller capacity batteries when it comes to portability, being one of the largest and heaviest batteries of the entire group. This rectangular battery is 6.38" long, 2.38" wide, and almost an inch thick (0.94").
It has a considerable heft to it, weighing in just shy of a pound, or 14.59 oz. For reference, this is three times the weight of the lightest battery pack in the group.
This weight and bulk combine to make it much harder to fit this portable battery into a pocket.
This giant battery barely fits in most front pockets.

This battery actually felt alright in a back pocket when sitting down, but was definitely unpleasant to sit with in a front pocket. Its weight is also noticeable.

Capacity
The RAVPower Ace 22000 has a stated capacity of 22,000 mAh. Using the load resistor, we were able to extract about 66% of this, or 14,220 mAh, with a 2.4A discharge rate. We repeated this test with the discharge rate set for 1A, but only got a little bit more energy out of it, 14,337 mAh.
The advertising claims of this portable charger stood up very well to our testing process. RAVPower claims that this battery can charge a Samsung Galaxy S8 4.4 times, an iPhone X 4.9 times, or an iPad Mini 4 2.6 times. We got 5.3 Samsung S8 charges from the Ace, well exceeding the expected amount.

Added Convenience
This battery doesn't really have any integrated convenience features, lacking any built-in cables, recharging methods, or a flashlight. It does include a pair of micro USB cables and a 1-year limited warranty.
The Ace 22000 can charge up to three devices at once, with each USB port able to output up to 2.4 amps.

Recharge Time
The RAVPower Ace 22000 delivered a less than stellar performance in this area.
It took close to the longest to charge, with about 485 minutes elapsing before the LEDs showed the battery to be completely full.

Value
This portable charger isn't the best option if you are trying to shop on a budget, as there are much smaller batteries that cost quite a bit less and mean you will just have to recharge them more frequently.
Conclusion
Overall, the RAVPower Ace 22000 is the best option if you are looking at charging a bunch of different devices or if you need maximum power for an extended off-the-grid outing.
