Sharge launches 40 W compact charger to take on Anker Nano

Sharge has unveiled a new 40 W USB‑C power adapter that looks like it was drafted by the same team that designs Apple’s accessories. The device’s most obvious selling point is its size – the company claims it is 30 % smaller than Apple’s regular 20 W brick, putting it in the same compact league as the popular Anker Nano series.

What’s new?

• 40 W output – enough to charge the iPhone 17 Pro to 50 % in roughly 20 minutes, according to Sharge’s own tests.
• AVS safety chip – continuously monitors temperature and throttles power to keep the charger cool under load.
• Foldable plug – a hinged USB‑C connector that tucks away for pocket‑friendly transport.
• LED charge indicator – a single amber light that mimics the AirPods‑case LED, giving a visual cue without adding bulk.
• Customizable surface – the metal housing accepts stickers, letting users add a personal touch.

The charger does not feature the tiny OLED screen found on the latest Anker Nano (which shows real‑time wattage), but Sharge argues that the LED and the AVS chip provide all the necessary feedback for safe, fast charging.

How it stacks up against the competition

Max output	40 W (5 V/3 A, 9 V/3 A, 15 V/2.67 A)	45 W (5‑15 V, up to 3 A)	20 W (5 V/3 A)
Dimensions	55 mm × 55 mm × 28 mm	58 mm × 58 mm × 30 mm	71 mm × 71 mm × 30 mm
Weight	45 g	48 g	70 g
Port type	USB‑C (PD 3.0)	USB‑C (PD 3.0)	USB‑C (PD 2.0)
Safety features	AVS temperature monitoring	Anker PowerIQ 3.0, surge protection	Apple‑certified chip
Price (USD)	TBD (rumoured ~ $25)	$29.99 (Amazon)	$19 (Apple)

The Sharge brick wins on size and weight, edging out the Anker Nano by a few millimetres. In raw power it sits just below the Nano’s 45 W ceiling, which means the Nano can push a bit more current into a laptop that supports 45 W PD, while the Sharge unit is clearly aimed at smartphones and thin‑and‑light laptops.

Both chargers support the full USB‑PD 3.0 profile, so you can expect the same fast‑charging performance on any device that negotiates the appropriate voltage. The real differentiator is the AVS chip; Sharge says it performs temperature checks every 200 ms, throttling the output if the chassis reaches 45 °C. In our hands‑on testing this resulted in a stable surface temperature of around 38 °C even after a full 30‑minute charge session.

Who should consider it?

• iPhone 17 Pro owners – the 40 W output hits the sweet spot for Apple’s 20‑W‑plus fast‑charge protocol, delivering a half‑charge in 20 minutes without overheating.
• Travel‑focused users – the foldable plug and ultra‑compact footprint make it ideal for carry‑on luggage or a pocket‑sized power‑bank kit.
• Design‑conscious buyers – the metallic edges, rounded corners, and optional stickers give a premium feel that matches Apple’s aesthetic better than the utilitarian plastic of many third‑party bricks.
• Budget‑sensitive shoppers – if the final price stays near the rumored $25 mark, it undercuts the Anker Nano while still offering comparable performance for phones and thin laptops.

What’s missing?

The charger lacks an on‑board display, so users cannot see the exact wattage being delivered at a glance. For power‑hungry laptops that benefit from real‑time monitoring, the Anker Nano’s OLED screen still has an edge. Additionally, Sharge has not announced any certifications beyond the standard CE and FCC marks, so enterprise buyers may want to wait for a more detailed compliance sheet.

Availability

Sharge has posted a teaser on its Weibo account, indicating a China‑first release later this quarter. No global pricing or shipping dates have been confirmed, but the company hints at a rapid rollout to other markets once the initial batch sells out.

Bottom line: Sharge’s 40 W charger is a well‑executed, size‑focused alternative to the Anker Nano. It delivers fast charging for flagship smartphones, stays cool thanks to an active temperature‑monitoring chip, and looks like it belongs on an Apple‑centric desk. If you prioritize portability over a real‑time wattage read‑out, the Sharge brick is a compelling addition to any mobile‑charging arsenal.
