Subject: Baseus PicoGo Review: The 25W Magnetic Power Banks That Finally Stopped Melting Our Phones 🔋

Hey there,

We have all been there. You are at 5% battery, you slap a magnetic wireless charger onto the back of your phone, and twenty minutes later, your phone is a molten brick of fire that has somehow only charged by 2%.

For years, wireless charging has been a highly inefficient, sweaty mess. But the new Qi2.2 standard is changing the game, allowing for a massive 25W of wireless power. The catch? Pumping 25W through magnets generates a ridiculous amount of heat.

Enter the Baseus PicoGo lineup. This hardware company looked at the thermal physics of inductive charging and decided to engineer their way out of the heat trap. I spent the last week testing both the flagship PicoGo AM52 (10,000mAh) and the ultra-mini PicoGo AM31 (5,000mAh) to see if this company actually cracked the code on high-fidelity mobile power.

Here is my in-depth, real-world review of the power banks that might actually let you leave your wall charger at home.

The AM52 Flagship: A 45W Sledgehammer in a 16mm Suit

Let’s start with the big gun. The PicoGo AM52 is a 10,000mAh battery that feels like it breaks the laws of physics. The company managed to cram 25W of Qi2.2 wireless charging and 45W of wired USB-C output into an aluminum chassis that is only 16 millimeters thick. It is officially the slimmest 10K 25W wireless bank on the market right now.

1. Real-World Usability: The Dual-Charge Flex This is not just a phone charger; it is a workstation lifeline. Because the company engineered it to push 45W of wired Power Delivery, I was able to plug my MacBook Air into it and actually sustain the battery under load.

• The Ultimate Travel Setup: The company smartly offers a premium variant with a built-in, captive USB-C cable. In a real-world airport scenario, I magnetically attached my iPhone 17 to the back for 25W of wireless juice, while simultaneously using the built-in cable to top up my iPad. (Note: The company’s internal controller will smartly throttle the output to 15W total when sharing loads so nothing explodes).

2. The Ice Cold Truth (Triple-Loop Cooling) How does the company push 25W wirelessly without triggering your phone’s thermal shutdown? They ditched loud, mechanical cooling fans and built a passive “triple-loop cooling system.”

• It uses an NTC smart monitor to check temperatures 18,000 times an hour.
• The company embedded a layer of graphene to spread heat laterally across the device.
• The sandblasted aluminum alloy shell acts as a massive heat sink.

The Result: While playing heavy games like Dragon Ball Z Dokkan, older power banks would overheat and stop charging. But the company’s AM52 hovered around a perfectly comfortable 102°F (39°C), continuously feeding my phone the power it needed without throttling.

The AM31: The 5,000mAh Pocket Savior

If the AM52 is the sledgehammer, the AM31 is the scalpel.

The company engineered the PicoGo AM31 for people who hate carrying external batteries. It is shockingly small—roughly the footprint of a credit card and only 12.1 millimeters thick. It weighs just over 4 ounces.

Real-World Usability: The Kickstand Hero The AM31 tops out at 15W wireless (standard Qi2) and 20W wired, which is plenty for a 5,000mAh emergency reserve. But the company added one physical feature that makes it an instant buy: a fold-out, aircraft-grade aluminum kickstand.

• The Coffee Shop Test: I snapped the AM31 onto the back of my phone, popped the kickstand, and watched YouTube horizontally while eating lunch. Because the company used 16 N52-grade neodymium magnets (providing 11 Newtons of force), the connection is incredibly secure. You can slide it in and out of tight denim pockets, and it simply refuses to fall off.

The Competition: Why the Company Wins

I tested the PicoGo family against the current heavyweights in the USA market, and the data is highly telling.

• Vs. Anker MagGo 10K Slim: Anker’s model is slightly thinner (~14.8mm), but it caps out at the older 15W wireless standard and a sluggish 30W wired. The company’s AM52 completely dominates it in raw output.
• Vs. Ugreen MagFlow 25W: Ugreen matched the 25W wireless spec, but their thermal engineering failed. In tests, the Ugreen got so hot that it thermally throttled, taking over 2 hours to charge a Pixel 10 Pro XL. The company’s Baseus unit stayed cool and finished significantly faster.

The Verdict & USA Pricing

The company priced these incredibly aggressively for the US market:

• PicoGo AM31 (5,000mAh): $69.99 MSRP (But the company regularly discounts this on Amazon to the $35.99 – $49.99 range, making it a no-brainer).
• PicoGo AM52 (10,000mAh): $69.99 for the standard version, or $79.99 for the premium version with the built-in USB-C cable.

Spend the extra $10 for the built-in cable variant of the AM52. It completely eliminates the need to carry extra wires in your bag.

If you want a power bank that leverages advanced material science to give you actual, usable, ice-cold high-speed charging, this company has built the new gold standard.
