SANWA SUPPLY launched the TAP-SLIM7U-15BK power strip on May 15, 2026, packing USB Power Delivery up to 100W into a GaN (gallium nitride) chassis that measures just 18mm at its thinnest point[1][2]. With 2 AC outlets, 2 USB Type-C ports, and 1 USB Type-A port, it can charge up to five devices simultaneously, and the SANWA Direct retail price is 9,480 yen (tax included)[1][3]. For anyone who wants to consolidate a desk-side power strip and a USB fast charger into a single unit, this product fills a long-standing gap, and the practicality of being able to toss it into a business-trip bag is something I have not felt this excited about in a while.

GaN squeezed into an 18mm-thin chassis: "more than enough for a laptop" specs

The TAP-SLIM7U-15BK's headline feature is packing up to 100W of USB PD into a body whose thinnest point is just 18mm[1][3]. The two USB Type-C ports each deliver up to 100W when used as the sole port, while the single USB Type-A port outputs up to 18W[3].

GaN is a semiconductor that can operate at higher voltages and frequencies than silicon, with less loss during power conversion, which makes it well suited to balancing heat dissipation and miniaturization. SANWA SUPPLY leverages these characteristics to enable fast charging of high-spec laptops directly from the strip, with no separate AC adapter required[2]. A smart IC automatically distributes the optimal output to each connected device, so it can supply a steady 65W to a laptop while charging other USB devices at the same time[2].

The body measures roughly 60 x 137 x 18mm, weighs about 249g, and ships with a 1.5m cable[3]. It is clear from the design that SANWA SUPPLY has built this not only for permanent desk use during telework, but also for hauling it out to business trips and meeting rooms[1].

Slim L-shaped plug and shutters: relentless focus on "stays out of the way against the wall"

Looked at as a spec sheet, this could read like just another USB-equipped power strip, but the product photos make it clear that the interference-prevention details have been worked through carefully[3].

The plug is a slim diagonal L-shape, with the cable exiting at an angle so it does not bend even when pressed against a wall, and it stays out of the way of adjacent outlets[2][3]. The AC outlets feature dust-proof shutters that block dust and foreign objects from entering unused ports[3]. On top of that, an LED indicator shows power status at a glance, and rubber feet keep the strip from sliding around when placed on a desk[3].

The whole product is built around the "unobtrusive, no accidental unplugging, no in-the-way" philosophy that matters most when the outlet is tucked away behind furniture or under a meeting-room table, and it should be a welcome design for anyone who wants to keep their desk clean.

9,480 yen direct: one unit to consolidate telework, business trips, and meeting rooms

The SANWA Direct retail price is 9,480 yen (tax included)[1][3]. When you buy an AC power strip and a USB charger separately, cables tend to multiply on top of the desk, and this product is positioned to collapse that into a single unit[1].

SANWA SUPPLY positions the use cases as telework, business trips, and meeting rooms, emphasizing that a single TAP-SLIM7U-15BK can also serve as a laptop power supply[1]. Compared with multi-port tower-type strips, the number of simultaneously connectable devices is modest, but in exchange the chassis is thin enough to fit in a bag, and the PD 100W support means it can step up to serious laptop charging too, which strikes a friendly compromise for frequent travellers.

As a gadget fan, the prospect of consolidating what used to be a "slim power strip plus a PD 100W charger" into a single piece of luggage is satisfying to imagine, and the 9,480 yen price tag looks far from unreasonable in that light.

Summary

The SANWA SUPPLY TAP-SLIM7U-15BK is a power strip that packs GaN-based USB PD up to 100W and five-port simultaneous charging into a body whose thinnest point is just 18mm, launched on May 15, 2026 at a SANWA Direct retail price of 9,480 yen (tax included)[1][3]. The careful build of the slim L-shaped plug and the dust-proof shutters leaves a strong impression of attention to desk-side usability, and for anyone looking to cover telework, business trips, and meeting rooms with a single device, this looks like a strong candidate.
