I’m always on the lookout for new ones that are pocket friendly Portable chargers Which is thin and lightweight, Baseus recently released a 5000 mAh battery Bikogo Air AM71 It’s easily among the thinnest and lightest power banks I’ve ever tested. It is only 0.27 inches (6.9 mm) thick and weighs about 3.7 ounces (105 grams), which is slightly thinner and lighter than the previous Baseus device Ultra-slim PicoGo magnetic power bank and Anker Nano MagSafe Portable Charger ($55), both of which are 0.3 inches thick and hold 5,000 mAh batteries.
But is PicoGo Air better than Anker? The short answer is: yes in some respects; In some ways, no.

The Baseus PicoGo Air AM71 is slightly thinner and lighter than the Anker Nano MagSafe.
What makes the Pico Air AM71 better?
- price: While the PicoGo Air AM71 lists for $70, code applied EHYGXRMR in Checkout on Amazon It brings the price down to $40, which is $15 less expensive than the Anker Nano MagSafe. The code is valid until July 31st.
- Size and weight: The PicoGo Air AM71 is slightly thinner than the Nano MagSafe and definitely feels lighter in your hand. However, they have roughly the same overall footprint.
- Wired charging is a little faster: The PicoGo Air AM71 offers 22.5W wired fast charging, compared to 20W for the Nano MagSafe.
- Braided micro USB-C cable included: You get a well-designed short cable for wired charging that feels sturdy.
- NFC PowerSense feature: When logged into the Baseus app, hold the PicoGo Air AM71 in front of your phone and tap to tether via short-range NFC to view battery status.
The PicoGo Air comes with a short braided USB-C cable for faster wired charging.
What makes it not quite good
- Wireless charging speed: Does not support PicoGo Air AM71 Qi2 wireless charging It only charges at 7.5W speeds in wireless charging mode. (Bassius earlier Ultra-slim PicoGo magnetic power bank Offers the same 7.5W wireless charging speed.)
- The battery heats up a little more: While the PicoGo Air AM71 has insulating layers of graphene and airgel and is designed with a “proprietary thermal management system, featuring a compact heat dissipation design that increases the cooling surface area by 50%,” according to the company, it does get a little warm, especially in wired charging mode. However, it still worked great in wireless charging mode.
- The NFC PowerSense feature is tricky: The battery monitoring feature only provides a quick snapshot of battery health, not real-time data. It also didn’t show me the output power; Only input power.
- The magnet doesn’t seem to be all that strong: The PicoGo Air AM71 sticks well to the back of my device iPhone 16 Pro and iPhone 17 (I’ve tried it with a few cases), but I would say the Anker magnets seem a little stronger. No ring is included for Android devices – I tried it with a Google Pixel 9 – but some people like me have already glued a metal ring to the back of their phones Android phone To mimic MagSafe.

Final conclusions for the Baseus PicoGo Air AM71
The Baseus PicoGo Air AM71 is an ultra-thin, lightweight, pocketable power bank that’s easy to recommend, although it does have some drawbacks. I ended up sticking it to the back of my iPhone 16 Pro, but I used it more in wired mode (with the included short braided cable) than in wireless mode, since the phone charges faster via cable. Note that although a 5,000 mAh battery should be able to fully charge an iPhone 16 Pro or iPhone 17, it can fall a bit short due to capacity loss due to heat and voltage conversion.
The Pico Go Air AM71 offers small advantages over the previous version Ultra-slim PicoGo magnetic power bankincluding a thinner design, faster wired charging, and better cooling. But the older model sells for about $25.
The Baseus PicoGo AM52 is about twice the size and weight of the PicoGo AM71, but it’s slim for a 10,000 mAh battery and has a built-in USB-C cable for wireless charging.
For those looking for a higher-capacity charger, Baseus recently released the 10,000mAh PicoGo AM52 battery (about $55), which is Qi2 certified, offers wireless charging speeds of up to 25W, and has a built-in cable for up to 45W wired charging. Note that you’ll only get short bursts of 25W wireless charging speeds with the battery speed reduced to avoid overheating.
As long as you’re okay with the extra size and weight — the PicoGo AM52 is about twice as thick as the PicoGo Air AM71 at 0.6 inches, and weighs about twice as much at 6.95 ounces — it might be the better choice. Apply code UTYJDF7V at checkout on Amazon to lower its price to $43.
All that said, I personally prefer a very light and slim power bank. But that’s just me.
