Anker Nano 30W vs Belkin WCB009: Which Charger Fits Your Setup?

Pick the Anker for a compact one-device USB-C setup; pick the Belkin if you also need USB-A at the same outlet. Belkin's 42W is the total across its 30W USB-C and 12W USB-A ports, not a 42W USB-C output. Both publish a 30W maximum for USB-C, and actual fit depends on the outlet layout.

The buying question

Is one USB-C port enough, or is Belkin's extra USB-A port useful enough to choose the dual-port charger?

Anker is a single-port 30W USB-C charger with a manufacturer-described narrow body; Belkin adds a 12W USB-A port alongside a 30W USB-C port, for up to 42W combined. Belkin's 42W total does not raise its USB-C-only maximum above Anker's 30W.

Quick verdict

Choose Anker Nano Charger 30W A2147 (Phantom Black) if

  • You need one USB-C port rated up to 30W and want Anker's manufacturer-described narrow design for a crowded power strip.
  • You are packing a single charger for one USB-C device and do not need USB-A at the same time.

When to skip: Your device requires more than 30W from a single USB-C port; neither published USB-C port exceeds 30W.
When the recommendation changes
  • If you need the USB-A port simultaneously with USB-C, Belkin's additional port matters; if the second port will go unused, both list a 30W maximum on USB-C.
  • If adjacent outlets are tight, check each published dimension against the physical strip layout; no general fit winner is established here.

The differences that matter

Port Mix And Simultaneous Device Charging

Anker Nano Charger 30W A2147 (Phantom Black)

One USB-C port; up to 30W maximum output.[1]

Belkin BoostCharge Dual Wall Charger 42W WCB009dqWH (White)

One USB-C port up to 30W and one USB-A port up to 12W; up to 42W total.[2, 3]

What this changes: Belkin's practical difference is the extra USB-A connection for a second device. Its combined 42W rating does not mean the USB-C port alone can exceed Anker's 30W maximum.[1, 2]

The better fit depends on your priorities

Crowded Outlet And Travel Fit

Anker Nano Charger 30W A2147 (Phantom Black)

Manufacturer-published dimensions are 1.12 × 1.12 × 1.39 inches; Anker describes the design as narrow enough to fit between larger plugs on a power strip.[1]

Belkin BoostCharge Dual Wall Charger 42W WCB009dqWH (White)

Manufacturer-published dimensions are 2.8 × 1.7 × 1.1 inches (L × W × H).[2]

What this changes: Use the published dimensions and the layout of your own outlet or strip to check clearance. These measurements are not a side-by-side obstruction test, and plug orientation can change the fit.[1, 2]

The better fit depends on your priorities

Best for your routine

Charge one USB-C phone or tablet from a single wall charger.

No clear winner

Both manufacturers list a USB-C port with a maximum output of 30W. Actual charging depends on the connected device, cable, and protocol.

Charge a USB-C device and a USB-A device at the same time from one adapter.

Best fit: Belkin BoostCharge Dual Wall Charger 42W WCB009dqWH (White)

Based on listed features, not comparative testing.

Belkin documents a USB-C port and a separate USB-A port, while Anker documents one USB-C port. Choose Belkin only if that second port is useful to your device mix.

Fit a charger between neighboring plugs on a crowded strip.

The better fit depends on your priorities

Anker explicitly describes a narrow design for this use; the Belkin page provides its dimensions. Check the actual outlet spacing and plug direction rather than assuming either body will clear every neighboring plug.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

If the Belkin is currently more expensive, its extra USB-A port is useful only when you will use it alongside USB-C; this comparison does not establish a fixed dollar premium or payback point.

Catalog price observations are current-only; compare the live offers with your budget and feature needs at checkout.

Limitations

  • The listed wattages are manufacturer maximum ratings, not measured results from a controlled Anker-versus-Belkin test. No charging-time, thermal, efficiency, or reliability winner is established.
  • A device's charging protocol, cable, and state of charge can affect actual input power; verify the requirements of your specific device.
  • Published body dimensions do not guarantee clearance on a particular power strip. The article does not normalize plug orientation or claim an obstruction-free fit.
  • Check the selected package listing for cable contents; this comparison does not assume that either standalone charger includes a charging cable.

Questions shoppers ask

Does Belkin send 42W through its USB-C port alone?

No. Belkin lists up to 30W on USB-C and up to 12W on USB-A, for up to 42W combined. Its USB-C-only maximum matches the Anker's listed 30W maximum.

Will the Anker fit beside other plugs on every power strip?

Not necessarily. Anker describes its body as narrow enough to fit between larger plugs, but actual clearance depends on the strip's spacing and the direction of adjacent plugs. Compare the published dimensions with your own setup.

Methodology and sources

Matched the assigned product models to U.S. manufacturer pages, then compared port type/count, manufacturer-rated maximum output, and published enclosure dimensions. No charge-time or fit test was performed.

Automated tools helped organize the published product specifications; neither charger was physically tested for this comparison.
