Ugreen Nexode Air 45W Charger Slim – What’s New?

Ugreen has added a new member to its Nexode Air family: a 45 W GaN charger that fits comfortably in a pocket. The device measures 61 × 40 × 11.7 mm and weighs 53 g, giving it a footprint similar to a credit card. Its single USB‑C port delivers up to 45 W, and the chassis is finished in a brushed‑metal coating that feels solid while staying lightweight.

Safety suite	ThermalGuard temperature control, over‑voltage, over‑current, short‑circuit protection
Dimensions	61 × 40 × 11.7 mm
Weight	53 g
Price	US $39.99 (Ugreen store / Amazon)

The charger’s ThermalGuard system monitors the silicon temperature in real time and throttles output if the junction approaches 85 °C, keeping the outer shell comfortably cool to the touch.

How it stacks up against the Nexode Air 65W

Ugreen released a 65 W version earlier this year. The 65 W model is slightly larger (71 × 44 × 12 mm) and carries a second USB‑C port for dual‑device charging. In raw power it can push a 13‑inch MacBook Air to full charge in about 1 hour 45 minutes, whereas the 45 W Slim needs roughly 2 hours for the same task. The trade‑off is obvious: the 45 W charger saves 10 mm in length and 20 g in weight, making it a better fit for travel‑first users who rarely need to power a laptop and mainly charge phones or tablets.

If you primarily charge an iPhone 17, an iPad Pro or a thin‑and‑light laptop, the 45 W model hits the sweet spot. For power‑hungry 15‑inch laptops, the 65 W version remains the safer bet.

Real‑world charging performance

Ugreen’s marketing claims that the charger can bring a MacBook Neo from 0 % to 34 % in 30 minutes and an iPhone 17 from 0 % to 70 % in the same window. In our bench tests, the MacBook Neo (13‑inch, 45 W‑rated) reached 33 % after 30 minutes, confirming the claim within a 3 % margin. The iPhone 17, using Apple 2.0 fast‑charge, hit 68 % after 30 minutes, again matching the advertised figure.

The adaptive algorithm is noticeable during the final charge phase: once the battery passes 80 %, the charger backs off to a trickle of 5‑6 W, preventing the heat spikes typical of older chargers that stay at full output until the battery is fully topped off.

Who should consider the Nexode Air 45W Slim?

• Frequent travelers – Its pocket‑size and 53 g mass mean it can slip into a jacket pocket or a slim laptop sleeve without adding bulk.
• Apple ecosystem users – The charger supports USB‑PD 3.0 and Apple 2.0, delivering the 20 V / 2.25 A needed for the latest MacBook Air and iPhone 17.
• Android power‑hunters – QC 3.0 and Samsung Adaptive Fast Charging are built‑in, so a Galaxy S24 series will see its 25 W fast‑charge profile without issue.
• Budget‑conscious buyers – At $39.99 it undercuts many competing GaN bricks that sit above $50, while still offering a full safety suite.

If you regularly power two devices at once, the single‑port layout may feel limiting. In that case, the 65 W dual‑port charger or a separate 18 W USB‑C wall wart for the phone would be a better combination.

Availability and Outlook

The charger is available now through the Ugreen online store and via Amazon’s Ugreen storefront. Ugreen hinted at a Prime Day discount in June 2026, so early adopters may want to lock in the $39.99 price now.

Overall, the Nexode Air 45W Charger Slim delivers the expected performance of a GaN brick in a remarkably small package, with a smart‑charging curve that helps extend battery health. It won’t replace a high‑wattage laptop charger for power users, but for the majority of pocket‑sized charging needs it hits the mark.
