# NTONPOWER USB Power Strip: 3 AC + 4 USB, Flat Plug, and Who Should Skip It > 3 AC outlets, 4 USB (1 USB-C), flat plug, 0.32 kg. Why the missing surge protector is deliberate, and the 125 V limit.

This article goes past the spec sheet to answer the questions that actually decide a purchase: will it work in your setup, and what are you giving up? ## Overview The short version: this is a tool for people who need to run one to three AC devices plus several USB devices from a single wall outlet. A laptop adapter, a phone, earbuds, and a tablet off one socket is the use case it fits best. It is not designed as the hub for a desktop PC, monitor, and printer. The absence of a surge protector says so directly. Surge protection exists to keep lightning strikes and line noise from killing your gear, and a permanent desk setup wants it. NTONPOWER leaves it out deliberately, because cruise lines commonly ban surge-protected strips onboard. ## What Actually Sets It Apart Power strips get chosen by outlet count, but three things differentiate this one. **1. Flat right-angle plug. ** The plug lies parallel to the wall instead of jutting out, so a bed frame or bookshelf can sit flush against the wall. In hotel rooms and behind furniture, those few centimeters matter — and the cable no longer gets bent at the plug's base. **2. Wall-mountable. ** There are holes on the back and adhesive pads in the box, which gets the strip off your desk surface entirely. **3. Mixed AC and USB. ** Four USB ports, one of them USB-C, means one less charger in your bag. | Criterion | This product | Typical stationary strip | | --- | --- | --- | | Intended use | Travel, desk | Permanent PC/AV setup | | Surge protection | None | Usually included | | USB ports | 4 (1 USB-C) | 0–2 | | Plug | Flat, right-angle | Usually straight | | Cord length | ~1.5 m | 2–5 m options common | | Weight | 0.32 kg | Often 0.4 kg+ | These two categories do not really compete. Many readers will end up owning both and using each for what it is good at. ## Compatibility Guide **Voltage. ** The unit is rated 125 V. Japanese mains are 100 V, so running it there is well within spec, and the plug is the same flat two-pin type. The flip side matters more: **it will not work in 240 V regions** such as Europe or Australia. "Travel strip" does not mean universal here — treat it as a 100–125 V device (Japan, North America, Taiwan). **What you can plug in. ** The 3 AC outlets take ordinary 125 V appliances and PC peripherals. The 4 USB ports are aimed at phones, tablets, wireless earbuds, power banks, camera batteries, and e-readers charging at once. **Capacity. ** The published specs list no total amperage and no combined USB wattage. That is not something to guess at, so **if you plan to plug in a hair dryer, kettle, microwave, or heater, check the rated capacity on the product page first. ** As a general rule, high-draw heating appliances do not belong on a compact travel strip. Laptop adapters (65–100 W class), phone chargers, desk lamps, and monitors are all within the spirit of the design. **USB-C expectations. ** There is one USB-C port, but the data says nothing about Power Delivery support or output wattage. If charging a laptop over USB-C is your goal, confirm that spec before buying. If you cannot confirm it, assume you have four ports suitable for phones and tablets. **Physical fit. ** The cord is about 1.5 m. In hotel rooms where the outlet is on the far side of the bed, or under a desk, that can fall short. If you need 3 m or more, buy a longer strip instead. ## Product Info | Item | Specification | | --- | --- | | Brand | NTONPOWER | | Color | White | | Voltage | 125 Volts | | Weight | 0.32 kg | | Total USB Ports | 4 (including 1 USB-C) | | AC Outlets | 3 | | Power Cord Length | about 1.5 m | | Plug Type | Flat (right-angle) | | Wall Mount | Yes (holes and adhesive pads on back) | | Protection | Overcurrent, overcharge, short circuit, overheat, overvoltage | | Certifications | FCC, RoHS | | Housing Material | Flame-retardant ABS+PC (rated to 750°C) | The housing is flame-retardant ABS+PC listed at 750°C. That figure is a flammability-test rating, not an operating temperature — it means the plastic resists spreading a fire, which is exactly what you want from a power strip. Five protections are claimed: overcurrent, overcharge, short circuit, overheat, and overvoltage. Check the retailer's page for the latest price. Power strip prices move constantly with sales and stock, and this article will not update itself, so **check the current price on the product page before buying. Note also that the price label reads "Amazon US" while the link points to Amazon. co. jp — most likely a labeling quirk, but verify the currency and figure yourself. The box contains the strip and adhesive pads. Warranty follows manufacturer policy. ## How It Actually Reviews At that volume you are looking at a product that has sold steadily for a while, and 4.7 is high for this category. For power strips, the usual complaints are a dead outlet out of the box, slow USB charging, and adhesive that lets go. Whatever you pay, **test every AC outlet and every USB port once when it arrives. ** Discovering a dead port after the return window closes is the worst outcome. ## Best Use Cases - **Frequent travelers.** At 0.32 kg with a flat plug, it slips into a laptop sleeve or small pouch. Hotel rooms routinely offer two outlets; if you need to run a laptop adapter, phone, earbuds, and camera at once, this solves it. The lack of surge protection is what makes it cruise-ship friendly. - **Home office workers and students who want a clear desk.** Mount it on the wall or the side of the desk and cables stop crossing the work surface. - **Anyone tired of carrying a separate USB charger.** Four ports including USB-C means one fewer item in the bag. - **People with furniture pushed flush against the wall.** This is where the flat plug earns its keep outright. ## Before You Buy **There is no surge protector. ** That is a design choice, not a defect, but it limits the use case. Do not consolidate a desktop PC, NAS, external drives, or game consoles onto this strip. Keep a surge-protected strip for the permanent setup and use this one for charging and travel. **No PSE listing appears in the data. ** The certifications shown are FCC (US radio regulations) and RoHS (hazardous substances) — neither one certifies a power strip for routine use in Japan, where PSE under the Electrical Appliance and Material Safety Act applies. For occasional travel use that may not matter; **for permanent home use, confirm the PSE mark on the product page or on the unit itself. ** If you cannot confirm it, a domestically certified strip is the safer buy. **It will not work at 240 V. ** Do not let the word "travel" send this to Europe or Australia with you. **Combined USB output is not published. ** Multi-port chargers generally reduce per-port output when several ports are in use, so do not assume four devices will all fast-charge. Power-hungry devices are better served by their own adapter in an AC outlet. **Do not over-trust the adhesive mount. ** Adhesive pads struggle on textured wallpaper, sand-finish walls, and painted surfaces, and when they fail they sometimes take the wallpaper with them — plus the plug and cable add hanging weight. In a rental, use the rear holes with screws, or stick it to a desk leg or side panel where a failure costs nothing. Clean oil and dust off the surface first either way. **1.5 m can be short. ** For stationary use, measure the distance from your outlet to the intended spot before ordering. **Verify the listing yourself. ** Amazon product pages sometimes carry manufacturer, model, or accessory details that do not match the physical product. This article covers the NTONPOWER strip under ASIN B07G21DRHV; **before adding it to your cart, confirm from the product images and title that you are getting the 3 AC + 4 USB flat-plug version. ** The same brand often lists several port-count variants side by side. ## FAQ **Q. Will it work on Japan's 100 V outlets? ** A. Yes — 125 V rated means 100 V is within spec, and the plug shape matches. For permanent use in Japan, check for a PSE mark first. **Q. Can I take it abroad? ** A. Fine in 100–125 V regions (Japan, North America, Taiwan). Not usable in 240 V regions such as Europe or Australia. **Q. Is it allowed on cruise ships? ** A. Policies vary by operator, so check your cruise line's rules before boarding. **Q. Can it charge a laptop over USB-C? ** A. There is one USB-C port, but PD support and output wattage are not in the published data. Confirm the output spec before relying on it; otherwise use the laptop's own adapter in an AC outlet. **Q. Can I run my desktop PC setup from it? ** A. Not recommended — no surge protection, and the design targets travel. Use a proper stationary surge-protected strip for that. **Q. Are screws included for wall mounting? ** A. Adhesive pads are included. The rear holes allow screw mounting, but assume you will supply the screws. ### Product Disclosure (Amazon) - Manufacturer: NTONPOWER - Seller: fuji.harmotech - Fulfilled by: fuji.harmotech - ASIN: B07G21DRHV - Note: This article covers a manufacturer-made product based on Amazon listing details.
