Anker Nano A2738 car charger review: is the retractable cable worth it?

Verdict: The Anker Nano 75W USB-C Car Charger with Retractable Built-In Cable (A2738) makes sense when a loose charging lead is the daily annoyance you want to remove. It can serve two devices, but the attached cable tops out at 45W and the separate port at 30W. Skip it if you need higher power to one laptop or are content with a basic charger and removable cable.

Pros

• An attached retractable USB-C cable gives your main device a lead that stores with the charger.
• A separate USB-C port accommodates a second device with its own cable.
• Two connections provide up to 75W combined. Anker product page ChargerLAB teardown

Cons

• Neither connection supplies 75W to one device.
• PPS charging is limited to 30W; this is not a 45W Samsung PPS charger.
• An integrated cable makes its reach and mechanical wear part of the buying decision. Long-term retractor durability is not established by the sources used here. ChargerLAB teardown

Can it charge two devices at once?

Yes: the retractable cable and separate USB-C port provide two charging connections. Keep these limits distinct:

ChargerLAB documented these ratings on the A2738 label and checked advertised charging profiles with test equipment. The figures are capability ceilings, not a promise that every device reaches them or sustains them throughout charging. ChargerLAB checks

A phone plus a passenger’s device is the straightforward use case. The second person needs a separate cable. For laptop charging, check supported input profiles and power demand; a laptop expecting more than 45W may charge slowly or lose battery under heavy use. The combined headline does not change that single-device limit.

Is the retractable cable worth choosing?

It is most useful if the same USB-C device charges near the console every day. Pulling out only the needed length can reduce loose cable in the cabin, and you are less likely to leave the lead at home. That is our workflow assessment, not a durability finding. Anker design

ChargerLAB measured a cable around 72cm long. Check the distance from your vehicle’s socket to the phone mount, allowing slack and a clear route. A fixed-length built-in lead may be inconvenient for a distant mount or passenger; a normal charger lets you choose a longer cable and replace it independently. ChargerLAB measurements

The evidence here does not establish retraction life, hot-car performance or fit around your gear selector and console trim. Those practical checks matter more than buying by the largest wattage number.

Who should buy it, and who should skip it?

Buy it for cable cleanup with occasional second-device charging. The retractable lead is the reason to choose this design. If a cheaper basic charger meets your device’s requirements and you already have a suitable cable, there is little reason to pay extra just for storage.

Skip it for more than 45W to one device, 45W PPS charging, or a reach the attached cable cannot provide. This analysis covers US model A2738, ASIN B0D9NPDLG3. Protein Picks has not tested it.
