Anker MagGo 10K Slim Power Bank review: On-the-go charging with wireless smarts

Power banks are all the rage at the moment, and since the Wireless Power Consortium released the Qi2 standard back in April 2023, we've seen an upsurge in power banks dedicated to wireless charging.

The Anker MagGo Power Bank (10K) is the current winner of the best iPhone power banks, but since then, Anker has released a slimmed-down version of the same device. The charging specs are almost identical, although you get three more watts on power delivery from the USB-C. It also adds support for the iPhone 16.

The big selling point of the MagGo 10K Slim is its portability. It's nowhere near as small as the Anker Nano 621 Power Bank (5,000mAh) which wins the prize for the most pocketable. Despite that, it still measures 104 mm x 70.6 mm x 14.7 mm and weighs 200g, which is small enough to be considered portable.

In this review we'll dive into the specs and design as well as how it performs on a day-to-day basis.

Anker MagGo 10K Slim: Specifications

Anker MagGo 10K Slim: Price

At $74.99 / £69.99, the Anker MagGo 10K Slim is a little more affordable than the original (non-slim) version, but there are still more affordable alternatives out there. This is especially true if you're happy dropping down to 5,000mAh power. At the time of writing, Anker are offering 15% off the retail price, and we often find similar deals available elsewhere.

Anker MagGo 10K Slim: Design & Handling

The Anker MagGo 10K Slim Power Bank boasts a metal frame and a matte UV finish. It also incorporates aerogel thermal insulation and is made with 75% recycled materials. The highlight, though, is the liquid silicone covering on the front and back, which provides additional grip. I found this especially helpful when moving the device in and out of my pocket.

The circular Qi2 wireless charging area has a slightly raised border, which is a nice touch and may well help visually impaired users locate their iPhone correctly. Touches like this, as well as the smooth corner bevels, show the attention to detail that Anker has given this device.

At the bottom of the power bank, you'll find battery LED indicators so you know how much juice you have left. I would much rather see a small screen integrated here, even if it only detailed the battery percentage. Alongside the indicators is a USB-C port. If I were being fussy, then I'd like two of these ports so I could charge my smartwatch at the same time as my phone.

Compared to the original non-slim version, there is no flick-out stand. This would be a nice-to-have, although it doesn't particularly affect its functionality. This is one of the downsides of portability, although I do wonder if Anker could integrate one into the case without compromising on the overall thickness.

Anker MagGo 10K Slim: Performance

Anker advertises that the Anker MagGo 10K Slim Power Bank is capable of delivering 15W of power for wireless charging and double that for wired via USB-C. I tested the performance of this device using my iPhone 12.

In terms of wireless charging, I was able to charge my iPhone from 0% to 50% in 45 minutes and from 0% to 100% in 145 minutes. As expected, the charging time for the final 10% was rather slow. These times are comparable to other power banks I've used. I'm also pleased to report that during charging, I didn't experience the power bank heating up, although my phone warmed up a little.

Wired charging was significantly faster, and that is still my preference. I prefer avoiding hot phones and slow charging speeds, but it's not as convenient as the wireless alternative. I was able to charge my iPhone 12 from 0% to 50% in just over 30 minutes, and a full charge took 95 minutes.

Using a cable capable of 30W power delivery, I was able to recharge the power bank itself in around 150 minutes. I doubt this will be much of a problem, especially given that the power bank can just be recharged overnight.

Anker MagGo 10K Slim: Verdict

This is Anker's slimmed down version of their Anker MagGo 10K Power Bank. In real terms that means it's 5mm thinner and 50g lighter. Personally, I don't think that's enough of a reduction to warrant the creation of a whole new power bank, and I actually found the 200g weight still a little heavy.

The loss of a screen is a little disappointing, and the battery LED indicators make it rather tricky to know exactly how much juice you have left. This is particularly annoying when running very low because, at that point, it's helpful to know exactly how much power you have left.

All that being said, I can't fault its performance in terms of wireless and wired charging. This is a 10K power bank that is as high-performing as they come. If you can set aside the fact that it's not as slim as you might like, then you won't be disappointed.

This Ugreen Nexode 10K power bank isn’t Qi2 certified, but still claims 15W wireless charging speeds, but also has a USB-C and USB-A wired port for charging a range of devices on the go.

If you just want sheer power and performance out of a power bank, then one of the best you can get is the Anker Prime 20K. There is no fancy wireless charging here, but the power bank does offer a big 20,000mAh tank and up to 200W combined output through its wired ports.
