I constantly seek compact portable chargers that fit easily in a pocket while remaining light. Baseus recently launched the 5,000-mAh PicoGo Air AM71, which stands out as one of the thinnest and lightest options I have evaluated. Measuring just 0.27 inches (6.9mm) thick and tipping the scales at roughly 3.7 ounces (105 grams), it edges out Baseus prior PicoGo Ultra-Slim Magnetic Power Bank as well as Anker Nano MagSafe model in slimness and weight, both of which measure 0.3 inches and contain similar battery capacity.

Still, the question remains whether the PicoGo Air surpasses the Anker unit. The brief response is that it excels in certain areas yet falls short in others.

What makes the Pico Air AM71 better

Price: Although the PicoGo Air AM71 carries a $70 price tag, entering the code EHYGXRMR during Amazon checkout reduces it to $40, which undercuts the Anker Nano MagSafe by $15. This promotion remains valid until July 31.
Size and weight: The PicoGo Air AM71 measures slightly thinner than the Nano MagSafe and feels noticeably lighter during use, though both share comparable overall dimensions.
Slightly faster wired charging: The PicoGo Air AM71 supports 22.5-watt wired fast charging, surpassing the 20-watt capability of the Nano MagSafe.
Braided mini USB-C cable included: A short, well-made braided cable comes with the unit for reliable wired charging sessions.
NFC PowerSense feature: After signing into the Baseus app, users can tap the PicoGo Air AM71 against their phone via NFC to quickly check battery levels.

What makes it not quite as good

Wireless charging speed: The PicoGo Air AM71 lacks Qi2 support and delivers only 7.5-watt wireless charging. This matches the speed of Baseus earlier PicoGo Ultra-Slim Magnetic Power Bank.
The battery heats up slightly more: Despite graphene and aerogel layers plus a proprietary thermal system that boosts cooling area by 50 percent, the unit warms noticeably during wired use. Wireless mode keeps temperatures lower.
The NFC PowerSense feature is finicky: Battery status appears only as a static view rather than live updates. Output power readings also failed to display, showing input power alone.
Magnet doesn't seem quite as strong: The unit attaches securely to an iPhone 16 Pro and iPhone 17 even with cases, yet Anker magnet feels marginally firmer. No metal ring ships for Android phones such as the Google Pixel 9, though many users already apply one to enable magnetic attachment.

Baseus PicoGo Air AM71 final conclusions

The Baseus PicoGo Air AM71 provides an exceptionally slim and lightweight power solution that slips easily into pockets and earns a solid recommendation despite minor limitations. I frequently placed it on my iPhone 16 Pro yet relied more on wired charging with the included braided cable for quicker results. A 5,000-mAh cell can typically top off an iPhone 16 Pro or iPhone 17, though real-world capacity may dip slightly from heat and conversion losses.

This model improves on the prior PicoGo Ultra-Slim Magnetic Power Bank with a thinner profile, quicker wired speeds, and enhanced cooling. The older version, however, sells for around $25.

Users seeking greater capacity may prefer the new PicoGo AM52 10,000-mAh model priced near $55. It carries Qi2 certification, supports up to 25-watt wireless charging, and includes a built-in cable for 45-watt wired sessions, though wireless output drops quickly to manage heat.

Given its added thickness of 0.6 inches and weight of 6.95 ounces, roughly double that of the PicoGo Air AM71, the AM52 could prove preferable for some. Enter code UTYJDF7V at Amazon checkout to lower its price to $43.

Ultimately I favor the lightest and slimmest designs, though preferences vary.
