One of their latest offerings is the Anker Nano Power Bank (5K, MagGo, Slim). It's a slim Qi2-compatible power bank with 15W MagSafe charging, but maybe its standout USP is its heat management. Thanks to graphene, dual NTC chips, and smart charging adjustments, the power bank stays 14 degrees cooler than the industry standard.

We’ve been testing the Anker Nano Power Bank (5K MagGo Slim) for about a month now, including a two-and-a-half-week trip through Tanzania, and it’s quickly become one of our favorite travel companions. From the moment we unboxed it, it felt different from your standard chunky power bank . Its slim, sleek, and curved design makes it comfortable to hold while still attached to your phone. If you’ve ever tried carrying a MagSafe battery in your pocket, you know it can get awkward—this one just works.

So, the overall construction of this thing, it feels very sturdy. I took this on a 2 and a half week trip to Tanzania and I used it pretty much every single day cuz I was out and about and we were gone for long stretches of time.

We love this Anker Nano power bank for one big reason: its built-in retractable USB-C cable is an unbelievably practical feature that makes on-the-go charging incredibly convenient. Our reviewer found this to be a massive plus, as the integrated wire is always ready.

Despite its compact size, the Anker 5K Slim has impressive charging performance. With a 5,000 mAh capacity, it’s great for topping up a smartphone during the day.

As someone who works a lot on the go, I rely on the Anker Nano Power Bank for its built-in USB-C cable, large 10K capacity, and fast 45W charging.

So basically this is the Anchor Nano Power Bank Mag Slim and excellent for um for any iPhone. I believe also for iPhone Air. This would be a great um addition for it. Um, and look at this. Compared with this one, this one has also 15 watts uh charging features. Compared with this one, this is of course it has a bigger capacity, but it's more bulkier. Here it is.

I used it heavily this past weekend while at Universal Studios, and it was awesome. Enough to get me through the day, but super thin.

The Qi Nano Power Bank is my favorite of the bunch, and the only improvement I'd like to see in a next-generation version is Qi2.2.

The Anker Nano Power Bank is probably the most convenient power bank you can buy. It’s very similar to the Anoer 533 Power Bank (PowerCore 30W) BUT with the added convenience of a built in USB C cable.

It's an awesome choice if you're looking for a portable power bank that's small enough to slide into a pocket or bag without adding a lot of bulk.

Despite its heating issues, it’s still a good charger to carry with you in case of emergency. It’s quite cheap compared to similar chargers like Apple’s MagSafe charger for iPhone Air and EcoFlow’s Rapid, and its slim form factor won’t add a ton of extra bulk to your pocket.
