Anker A2738 vs A2735: Match the Cable and Device Input

Choose A2738 for an attached USB-C lead; choose A2735 when you need a native USB-A socket. For a device documented to require 15V/3A, A2735 is ruled out, while A2738’s attached lead passes the published-rating check only: confirm protocol, reach and vehicle supply before relying on it.

The buying question

Which connection fits your cable setup, and can it meet your device’s documented single-connection input requirement?

A2738 supplies a retractable USB-C lead with a higher rated ceiling; A2735 provides a native USB-A socket but cannot meet a 45W USB-C requirement.

Quick verdict

When the recommendation changes
  • Your device specifically requires 15V/3A: only the A2738 attached lead lists that profile.
  • The attached lead cannot reach: a longer cable in the A2738 socket cannot preserve its 45W profile.
  • Your requirement depends on a disputed A2735 profile or on two devices at once; verify that exact setup before buying.

The differences that matter

Native Connector Cable Fit

Anker Nano A2738 Car Charger (Gray)

Attached retractable USB-C lead, extending up to 29.5 inches, plus a USB-C socket; no native USB-A socket.[1, 2]

Anker 323 A2735 Car Charger (Black, No USB-C Cable)

USB-C and USB-A sockets for separate cables.[3, 4]

What this changes: Choose A2735 when a native USB-A connection is required. Choose A2738 for an attached USB-C lead that reaches your device. Both accept a separate USB-C cable, so wanting a longer cable alone does not select A2735.[1, 2, 3, 4]

The better fit depends on your priorities

Single Connection Input Requirement

Anker Nano A2738 Car Charger (Gray)

The attached lead lists 15V/3A and 20V/2.25A, with a 45W maximum; the separate USB-C socket is limited to 30W.[1, 2]

Anker 323 A2735 Car Charger (Black, No USB-C Cable)

No USB-C profile in the examined official tables exceeds 30W. The tables disagree on some higher-voltage modes, PPS and simultaneous output; the selected unit’s full profile remains unresolved.[3, 4, 5]

What this changes: A device explicitly requiring 15V/3A needs 45W at that connection: A2735 fails this rating check. A2738 lists the required profile on its attached lead, but the device’s protocol, vehicle supply and cable reach must also match. A 30W ceiling does not establish compatibility with every device below it.[1, 2, 3, 4, 5]

The better fit depends on your priorities

Best for your routine

A USB-A cable must plug directly into the charger

Best fit: Anker 323 A2735 Car Charger (Black, No USB-C Cable)

Based on listed features, not comparative testing.

A2735 supplies the native USB-A socket. The device and cable still need to match its supported output.

One USB-C device specifies a 15V/3A input

Based on listed features, not comparative testing.

A2738’s attached lead lists that profile; A2735’s ceiling excludes it. This is a conditional specification fit, requiring matching protocol, sufficient lead reach and a suitable vehicle outlet, not verified charging performance.

Value and trade-offs

The offers shown are per listed package; check the quantities and current terms on Amazon before comparing totals.

Compare the complete setup cost, including any separate cable you need. Pay for a connection that solves your requirements, rather than a larger headline wattage.

There is insufficient verified price history for a purchase-timing recommendation.

Limitations

  • Anker’s A2735 US page and original guide disagree with its support table on higher-voltage modes, PPS and simultaneous total output. We cannot tie that disagreement to a documented hardware revision. Those details remain unresolved; the comparison uses only the shared ceiling to exclude a 45W requirement.
  • This is a single-device specification comparison. We did not test negotiated power, charging speed, heat, safety, cable life or vehicle fit. Do not add port ratings or assume these conclusions apply with two devices connected.
  • The A2738 guide lists 12V/8A or 24V/4A input; the A2735 US page lists 12V/5.6A or 24V/3.6A. Check the vehicle outlet rating and each charger’s instructions. Regional A2738 documentation supports hardware facts, not US warranty or delivery terms.

Questions shoppers ask

What if the A2738 lead cannot reach a device requiring 15V/3A?

Neither of these documented setups solves that combination. A2738’s separate USB-C socket is capped at 30W, so a longer cable there cannot replace the qualifying attached lead. A2735 also falls short of the required 45W. Look for a different charger with the needed profile on a connection that reaches.

Does a device rated below 30W work with either charger?

Not necessarily. Check its required voltage, current and charging protocol, plus the cable and vehicle supply. Maximum wattage alone is not a compatibility check, particularly where A2735’s official profile tables disagree.

Does this A2735 selection include a USB-C cable?

The black A2735 selection compared here is the no-USB-C-cable variant. Supply a suitable cable; do not assume a separately advertised cable bundle is the same offer.

Methodology and sources

We checked connector configuration and single-connection input requirements, retaining official-source conflicts rather than treating wattage as proof of compatibility.
