The problem it should solve
A charger can be small and still be the wrong purchase. Before comparing models, name the inconvenience you want to remove: a bulky adapter in a daily bag, an awkward fit beside another plug, or a missing charger at a second desk. If none of those applies and your current unit works, a replacement has little practical value.
What the listing establishes
Anker identifies this model as A2147, with one USB-C connection and a maximum output of 30W. That establishes its basic role; it does not establish the charging speed of your particular phone. Check the device maker’s required charging standard and the cable you intend to use against the exact regional listing.
Our decision table
| Your situation | Decision |
|---|---|
| One compatible device, limited bag space | Worth comparing with the charger you own |
| Phone and tablet needed at the same time | One port means taking turns or keeping another charger |
| Laptop is the main load | Check its recommended supply before buying |
| No problem with your current charger | Keep it; a smaller case alone is not a necessity |
Check the complete kit
Lay out the adapter, cable and any travel plug together. Compare that complete kit with what is already in your bag. Saving space at the wall does not help if you must add another adapter to charge a second device. Check that the cable reaches the socket you actually use without pulling the device toward the edge of a table.
What we cannot conclude
We have not measured charging time, temperature, power consumption or long-term durability. The comparison photo shows an Anker 511 beside an Apple adapter; its A2147 model label is not readable. Treat it as an illustration of physical size, not a laboratory comparison or proof of performance.
Before ordering
Confirm the model, plug, cable requirements and return terms. Our link opens the US store. A reader elsewhere should compare a locally suitable version and the full delivered cost before making a decision.
