Anker MagGo Power Bank 2 Pro review: Fast 25W charging with active cooling

25W wireless charging creates a lot of heat that can force an iPhone into a self-safety mode that throttles the amount of power going into it or even stops it altogether. That’s why cooling is so important with this level of charger power.

In our tests, the MagGo 2 Pro charged an iPhone 16 Pro to 50% in 30 minutes with active cooling enabled, compared to 33 minutes in Silent Mode. It also delivered 199% total charge in our capacity test, comfortably beating the 174% average for 10K power banks we’ve tested.

What is the exact battery capacity of the Anker MagGo Power Bank 2 Pro?

Although we’ve seen some larger, 10000mAh (10K milliamp hours) is the largest battery size that you can clamp to the back of your MagSafe iPhone without it being too cumbersome to pocket or just fall off through its own bulk. Smaller pockets will appreciate a smaller 5000mAh (5K) power bank. Read reviews of all the best magnetic power banks we have tested, both 5K and 10K.

While it’s industry standard to talk of “5K” and “10K” power banks, it should be noted that not all in each of these broad categories have exactly the same actual capacity. To be more precise you need to look at the battery capacity in watt hours (Wh) rather than milliamp hours (mAh). The Anker MagGo Power Bank 2 Pro’s 39.2Wh is higher than the average 10K battery capacity of 38.2Wh.

How fast is the Anker MagGo Power Bank 2 Pro?

For wireless power output the MagGo Power Bank 2 Pro is rated at the top 25W, using the fastest Qi2.2 technology. Only the iPhone 16 series and later can take all 25W of this power output, with older iPhones pegged back at 15W (still much faster than the 7.5W still offered by some battery packs). Note that the 17e is also limited to 15W, and the iPhone Air to 20W. If you own the iPhone 16e you’re out of luck as that curiously doesn’t support MagSafe charging.

In our tests the Anker MagGo Power Bank 2 Pro recharged our test iPhone 16 Pro to 50% in 30 minutes, which is what we’d expect from a 25W charger, and much faster than the average 45 minutes it would take with a 15W wireless charger. It rates as a couple of minutes faster than the average, although environmental factors have a large impact—mainly from heat. Later, we’ll look at how Anker’s smart fan impacts charging times.
