With a thickness of only 0.34 inches (0.86 cm), this force bank sets a new record for the slimmest magnetic power bank we have tested so far. With dimensions of 4 x 2.8 x 0.34 inches (10.2 × 7.1 x 0.86 cm) centimeters, it is also perfectly matched to iPhones that support magnetic wireless charging (iPhone 12 and later). At 4.3 oz (122 g) Maggo Slim 5K is also very light.
Despite its minimal dimensions, anchor has included a USB-C port, a four-joint battery indicator and an on / off button.
Test performance
With a capacity of 5,000 mAh (19.35Wh), Anker 5K Slim appeared impressive in our test. From an iPhone 16 -Pro down to 0% fee, Power Bank returned it to 77% before it was also used.
This measures well against other 5K magnetic power banks we have tested exactly matches the marked thicker (0.6 inch) ESR QI2 5K Maglim, although this power bank has a kicking stand which anchor Nano 5K Slim is missing.
Only Belkin BoostCharge Pro Magnetic Power Bank Qi2 beat it and then only marginally at 79%.
The closest power bank with regard to thinness, Baseus Picogo Ultra-slim 5K is only 0.02 inches deeper, but at 71% it did not measure in the speed tests.
Like its larger (although still pretty thin of 0.58 inches), higher capacity siblings, Anker Maggo 10K mucus, it used the QI2 wireless charging technology, so it can reach speeds of 15W, which is the same as Apple’s own Magsafe (as it is compatible) and twice as fast as older 7.5W Magnetic Power Banks.

Connect a device to Power Bank’s USB-C port and it can cord charging at 20W if you are in a hurry and have a cable to hand.
The battery protection with graphic cooling technology and double NTC chips adjusts the charge and must ensure a permanent temperature below 40 ° C. We noticed this in the summer’s heat wave with highly fluctuating charging times.
Charging an iPhone 15 we measured at least 22% and a maximum of 32% after 30 minutes. Charging an iPad Pro and MacBook Air M3 with 20W via the USB-C port was also no problem where we measured 27% and 14% respectively. Charging Maggo 5K Slim even took 1.5 hours, also at 20W input.

Should you buy Anker Nano Maggo 5k Slim?
Even anchor can’t do magic: 5K Maggo Slim Power Bank is record-breaking thin, but this also comes at the expense of temperature control icing noticeable as we tested at the height of this summer’s heat wave. It gets hotter than thicker alternatives when charging. Fortunately, there is a well -functioning protective circuit, but this leads to a fluctuating charging speed.
The extremely slim design of 5K Nano Maggo Slim is especially appealing to users who appreciate the mobility-mens they are still impressing with fast and powerful performance on its QI2 magnetic wireless charging pillow and USB-C ports.
