Problems, parts and running costs

Summary

A 100W GaN travel charger with built-in US, UK and EU plugs, three USB-C ports, one USB-A port and a small display that reads voltage, power and temperature, aimed at frequent international travelers. Check the 100W total ceiling before you buy: that is shared across all ports, not per port.

Strengths

  • One object replaces a charger plus separate plug adapters.
  • Built-in US, UK and EU plugs cover the common travel regions.
  • USB-C1 and USB-C2 each deliver up to 100W when used alone.
  • Four ports cover a laptop, a phone and smaller devices at once.
  • The display shows local voltage, output power and temperature.
  • A mechanical interlock keeps only one plug extended at a time.

Weaknesses

  • 100W is the total output ceiling, so a laptop and phone share it rather than each getting full speed.
  • USB-C3 and USB-A share a combined 15W when used together.
  • Sustained full-load operation can trigger overtemperature protection that reduces output.
  • The AU plug is not included, so Australia still needs an adapter.
  • The multi-port power split was not documented at launch, and owners could not find it.
  • No instrumented independent test of this exact model exists; the one review restates manufacturer specs.

How the power split works

The headline is 100W, but that is the total the charger can put out at once, not a budget each port gets. USB-C1 and USB-C2 can each deliver up to 100W when you use one of them alone; USB-C3 tops out at 15W and USB-A at 12W. Plug a laptop into USB-C1 and a phone into USB-C2 and they draw from the same 100W pool, and USB-C3 plus USB-A share a combined 15W when both are in use. Anker uses PowerIQ 4.0 to allocate power dynamically, so adding a phone does not necessarily starve the laptop, but the total never rises above 100W. The Gadgeteer, the only independent review found, makes this shared ceiling its main caveat, and one r/anker owner could not find the multi-port split documented when the charger launched.

The display and built-in plugs

The 1.3-inch LCD shows local input voltage, output power and temperature, and Anker says it detects local voltage in about a second. The body folds in US (Type A), EU (Type C) and UK (Type G) plugs, and the interlock keeps only one plug extended at a time. Anker’s blog table lists AU among the built-in plugs, but the product page and 9to5toys both state the AU plug is not included, so treat the built-in set as US, UK and EU. The charger accepts 100–275V input, which means it works in different regions, but it does not convert voltage for other appliances. It is an AC wall charger, not a power bank.

Evidence quality, owner reports and running costs

No lab has published an instrumented teardown of this exact model. The only dedicated third-party review, from The Gadgeteer, is non-instrumented and says its safety figures are Anker’s claims rather than its own test results, so treat it as spec confirmation. Owner evidence is thin: essentially one hands-on r/anker post, which liked the consolidation value but could not find the multi-port power split documented. A separate r/UsbCHardware report describes a boot loop on the 140W A2697 smart-display charger; that is a different model and only a family-level caution.

Running costs are low. There is no subscription or consumable, but the charger ships without cables, and output above 60W needs an E-marker USB-C cable, so budget for one if you do not have it. Anker’s US policy page gives chargers an 18-month standard warranty, while the bundle listing says 24-Exchange Service; the 18-month figure is the better-supported one. The warranty applies only in the country of purchase and is void if the product leaves that country.

Is it worth it?

Anker’s US product page lists the A140A at $79.99. At or below about $70 it is a strong consolidation buy for someone who travels between US, EU and UK outlets, because one object replaces a 100W charger plus two plug adapters and adds a live voltage and power readout. From $71 to $90 the feature set is competitive, but the 100W total cap and the missing independent test data cap the premium. Above $90 it is weak for pure domestic use: if you rarely leave your home plug region, a conventional USB-C charger is the simpler choice. If you need sustained multi-device fast charging, the shared ceiling and the overtemperature throttling matter more than the display.

Which model this is

This page covers the Anker Universal Charger, manufacturer model A140A, a 4-in-1 100W travel charger with a smart display, sold in Iron Gray and Starlight Silver. The Amazon listing for this model is ASIN B0GS5M96KD. Do not confuse it with the Anker Charger (100W, 3 Ports, Smart Display) model B121B, the Anker Prime Charger 100W (A2688), the Anker 140W 4-port PD 3.1 charger (A2697), or the older Anker 736, 717 and 737 GaN chargers; those are different models with different port counts, wattage and no built-in international plugs.
