Just saw the announcement post and ran down to my Apple Store! They have them but you have to ask for them to look it up and get it from the back.

First impression is great! It feels really nice in the hand, it’s WAY slimmer and lighter than the 10k, and I’m currently charging it up at the full 20 watts. Phone pictured is a 16 pro.

One thing to note, the blue model is much lighter (at least on the box photo) than the photo on the announcement post.

Not sure why no one is really talking about this. I attached comparisons of previous Anker Powerbank models for reference. Hopefully it helps.

It is my go-to battery bank now. It is the next best thing when compared to Apple's battery pack, and slimmer. It's wider, but actually surprisingly gives better grip. The Anker 622 (old 5K) was great, but too slow to charge and also got quite hot even as a qi1 charger. The Anker 10K is fantastic, but it's way too heavy.

Some things to note from my 1 week experience:

- It doesn't get hot that you might expect
- Magsafe attachment animation shows, but does not show in the battery widget

Thinking of getting a magsafe powerbank and came across this one. I’m looking for a thin and light preferably 5k or lower power bank, was wondering if the new qi2 5k slim from anker is worth it.

If anyone has experience with this anker one, was this any good/worth the price? Does it wirelessly charge at 15W, gets super hot? How does it compare to other similar magsafe batteries?

Open to other recommendations, I’m prioritising lightness, could be more compact but thicker, Qi2 is a plus but don’t want anything that runs super hot.

This is a English translation of my German written review you can find on this Sub -> Link

A good Qi2 power bank stands and falls with its heat development. Because the worse this is, the more the power bank throttles itself, and the slower the smartphone charges. While many 10,000 mAh models now achieve good charging results, it was and still is primarily the 5,000 mAh models that had the disadvantage here. The sometimes ultra-thin models too obviously could not maintain stable performance, too often this resulted in poor charging times that did not differ much from Qi at 7.5W.

The old Anker MagGo Slim with 5,000 mAh (A1667), which was only available exclusively through the Apple Store, was considered a particularly negative example here. Although the model is particularly thin and compact, reports on the net criticized the slow charging times. To see if something has actually improved with the new A1665 model, I will compare it in the following test with both the old model, which a reader kindly provided to me - thanks again! - as well as with the previous best Qi2, 5,000 mAh model: the INIU P71-E1.

An overview of all Qi2 power bank tests can be found here . Just search for "Qi2".

For comparison:

KU XIU S2 5k: 10,63 x 6,98 x 1,09 cm, 149g

Only the INIU is still a touch more compact and lighter. The new Anker differs only minimally in dimensions and weight, but visibly different materials were used. The new model is even more rounded and feels better in hand. Essentially, it shares the same design language as the MagGo Slim 10k model. Everything looks super premium. You have to give Anker credit for that.

Specs:

• 5.000 mAh bzw. 18,5Wh Capacity

• 5V 3A / 9V 2,22A

• C1: 20W PD Output, 20W PD Input

• Qi2: 15W wireless

• shared Performance:

• 12W per Kabel & 5W wireless

• PPS:

• NO PPS!
  

A few bullet points:

• same specs on paper to the old model, but the differences will be shown later

• Passthrough is supported

Net capacity:

• 13,81Wh bei 9V 2,22A (75%)

• 16,19Wh bei 5V 2A (88%)
  

The older Anker:

• 12,61Wh bei 9V 2,22A (65%)

• 15,91Wh bei 5V 2A (82%)
  

The INIU:

• 15,91Wh bei 9V 2,22A (88%)

• 16,01Wh bei 5V 2A (89%)
  

It's well-known that good values start at 80%. It's striking that both Anker models operate noticeably less efficiently under high load, which is particularly evident when looking at the INIU. However, at low loads, the models are all on par and perform consistently well. I'm used to significantly worse performance from no-name Qi slim power banks here. Kuulaa, Nohon, and similar brands sometimes deliver in the 60-70% range.

None of the models can output a constant 20W via cable. The newer Anker A1665 throttles down to 15W after 30 minutes. The older Anker A1667 throttled down after just 20 minutes. Both models were thoroughly cooled down beforehand to achieve the fairest possible results.

Qi2 Wireless Performance:
First off, wireless charging is incredibly susceptible to all sorts of factors that can negatively impact the charging result. To ensure the greatest possible comparability, I set the following test conditions:

As always, I used an iPhone 15 Pro, starting at 20% and charging it to 80%. The charges were repeated multiple times, and an average value was calculated. The room temperature was consistently 21°C, and charging was done without a case.

Why 20-80%? From 80% onward, the iPhone naturally throttles down and enters trickle charging. Comparability is no longer present there. And starting from 20% to represent a realistic everyday scenario, as many people charge their smartphones within this range.

It should, of course, be clear that these results aren't entirely comparable to real-world everyday experiences. Too many factors play a role here: 5G, temperatures, case, phone usage—generally anything that could lead to the phone heating up influences wireless charging. Therefore, please only view all results as a guideline!

In addition to the three Qi2, 5k power banks, I've included a Qi1, 5k Anker model and the 10k variant of the MagGo Slim for comparison. Also "nach" just means after, too lazy to edit these out. Sorry. :D

• Nach 40 Minuten: 71%

• Nach 50 Minuten: 80%
  

My observations:

• The new Anker 5k charges slightly faster on average, confirming the impression that there are minor improvements.

• Both Anker models charge slower than the previously best Qi2 5k, the INIU.

• None of the three models come close to the very good Qi2 10k models.

• Compactness remains a limiting factor.

• If you want the fastest wireless charging from a power bank, you have to go for a good 10k model like the Anker.

• The 5k Slim models, however, are excellent battery extensions, and especially the new Anker adds absolutely no bulk and sits perfectly.

• While all three 5k Slim models charge slower, they still achieve true Qi2 speeds, as seen in the first 20 minutes. They only throttle down more significantly over time.

• The old Anker 321 charges slower at 7.5W but maintains that charging power almost consistently.

• All mentioned models share one characteristic: they remain pleasantly warm. Under good conditions, none of the models overheat. This can, of course, change in everyday scenarios. However, there are also plenty of power banks that overheat even under perfect conditions.

• All models are recommendable in their own right; if you take a look at my Wireless Charging table in the Google Sheet, you'll see that most other brands achieve significantly worse results.
  

Input:
The newer power bank model charges in 1 hour and 38 minutes with a 20W input, while the older one takes about 5 minutes longer. However, even with charging, smaller optimizations are noticeable. The new model charges consistently at 20W and essentially reaches 90% charge within one hour, then tapers off very slowly. The old model charges alternating between 20W and 12W, and after about an hour, it has only charged to approximately 70-75%. So, if you don't always want to fully charge your power bank, you can take the new model off the charger after about an hour.

Conclusion:
Is the new Anker Nano MagGo Slim Qi2 5k a good model? That's a clear yes and no. Yes, it's better than the old model, but the improvements are limited. It's clearly slower than a good 10k Qi2 power bank, and it's also slower than the best 5k Qi2 power bank, the INIU model.

So, is there actually anything that speaks for this Anker compared to the INIU? Strictly speaking, no. The INIU is technically better, more efficient, much cheaper, and has small extras like a kickstand. However, it's nowhere near as well-built as the Anker. The Anker simply feels great in the hand; it's a clear premium product with premium materials by comparison. And considering its size and weight, it's not bad. It's better than most 5k Qi2 power banks, but for the price, it really should be the best. Unfortunately, it's not.
