What to know first
Consider the Anker Prime A2343 if you primarily need up to 100W from either USB-C port when charging one device and want spare ports for travel. With both USB-C ports occupied, expect a documented 65W/35W split. It is less compelling for 140W laptops, buyers who need predictable three-port allocation, or devices dependent on an undisclosed PPS range or proprietary charging protocol.
Why this is a clear buying-intent candidate
The A2343 appears under a stable Amazon ASIN and has been covered by multiple independent publications as a compact laptop-and-phone charger. Its two USB-C ports, legacy USB-A port, folding U.S. prongs, and worldwide-voltage input address a common travel-shopping need. Amazon availability, bundles, sellers, and review counts can change, so the draft does not treat a transient sales rank as evidence of product quality.
Port limits in plain English
One USB-C device can negotiate as much as 100W from either USB-C port. USB-A tops out at 22.5W. Occupying both USB-C ports changes the advertised allocation to 65W for the primary port and 35W for the secondary port. Pairing the primary USB-C port with USB-A produces a published 76W/22.5W split. These are ceilings; a device draws only the profile it supports.
The unresolved three-port question
The official manual promises no more than 100W total with all three ports in use but does not assign a limit to each port. One Anker product page publishes 46W, 30W, and 22.5W, while an Amazon-hosted guide publishes 65W, 24W, and 12W. Because those tables conflict, the defensible conclusion is only that three devices share approximately 100W and that a laptop will receive materially less than the single-port maximum.
Standards and cable requirements
Anker explicitly lists PPS and publishes USB-C profiles through 20V/5A. Those profiles support the charger's 100W ceiling but not 140W-or-higher USB PD Extended Power Range charging. Full output requires a 5A electronically marked USB-C cable; a 3A cable caps power at 60W. The exact PPS range is missing, so shoppers should verify model-specific Samsung or Pixel charging requirements rather than relying on the charger's total wattage alone.
Compatibility expectations
The manufacturer lists a broad range of Apple, Samsung, Dell, Lenovo, Chromebook, tablet, watch, and earbud products. That establishes intended compatibility, not guaranteed maximum speed. The device, cable, occupied ports, battery state, and thermal conditions all influence charging power. Anker also publishes a specific warning about M2 MacBook MagSafe charging and recommends USB-C-to-USB-C instead.
Reasons to choose or skip it
Choose it when one 100W-class USB-C laptop is the priority and the extra ports are conveniences. Skip it when the laptop requires 140W for its fastest mode, when three simultaneously connected devices need fixed guaranteed allocations, or when a device depends on a proprietary charging system. Independent reviews also indicate that the charger can become quite warm and that cheaper alternatives exist, so compactness and dual 100W-capable USB-C ports—not specifications alone—are the main reasons to shortlist it.
Evidence ledger
Anker A2343
Anker Prime 100W GaN Wall Charger (3 Ports)
- The charger has two USB-C ports and one USB-A port, with a stated maximum combined output of 100W.
- Either USB-C port supports the published single-port profiles 5V/3A, 9V/3A, 12V/3A, 15V/3A, and 20V/5A, reaching 100W at 20V/5A.
- The USB-A port is limited to 22.5W when used alone; Anker publishes 4.5V/5A, 5V/4.5A, 5V/3A, 9V/2A, 12V/1.5A, and 10V/2.25A profiles.
- Anker's consumer product page specifies a 65W plus 35W split when both USB-C ports are occupied. It recommends using the upper USB-C port for the laptop in this configuration.
- For the documented USB-C1 plus USB-A combination, Anker specifies up to 76W and 22.5W respectively. The manual confirms a 100W maximum for every two-port combination but does not provide all individual allocations.
- Anker states that the charger supports PPS and its PowerIQ 4.0 charging technology. The official materials reviewed do not publish the charger's complete PPS voltage and current range.
- The fixed 20V/5A ceiling places this charger in the 100W USB Power Delivery power class rather than the 140W-or-higher Extended Power Range class. It should not be purchased for 140W laptop charging.
- Reaching 100W requires a suitable 5A electronically marked USB-C cable. A conventional 3A cable limits USB-C power to 60W.
- Anker lists compatibility with MacBook Air and Pro models, iPads, Galaxy phones and tablets, Dell XPS and Lenovo ThinkPad models, Chromebooks, earbuds, and watches. Actual charging power remains limited by the connected device, cable, protocol, and number of occupied ports.
- Anker specifies universal 100–240V, 50/60Hz input. The U.S. model has folding wall prongs.
- Anker lists dimensions of approximately 1.7 by 1.5 by 2.3 inches and a weight of about 6.4 ounces.
- Macworld independently confirmed the 65W/35W two-USB-C split and reported that the charger became very warm while fast-charging a MacBook Air M3. TechRadar likewise found it compact and capable but noted that less expensive multi-port competitors exist.
- The 100W figure is a shared total, not 100W from each port simultaneously. Connecting another device reduces the power available to a laptop.
- Anker's documentation is internally inconsistent. Its regional product page gives a three-port allocation of 46W, 30W, and 22.5W, while an Amazon-hosted guide gives 65W, 24W, and 12W. The official manual states only a 100W three-port total. Buyers should not rely on a precise three-device split without confirmation from Anker for the exact hardware revision.
- Anker's support database contains an apparent error stating a 65W total maximum, despite listing 100W single-port output and 100W multi-port combinations on the same page.
- The charger cannot provide the 140W input used for the fastest charging supported by certain 16-inch MacBook Pro configurations and other USB PD Extended Power Range devices.
- PPS is supported, but the reviewed official documents do not disclose its complete range. Do not assume every Samsung Galaxy or Google Pixel model will reach its proprietary or highest advertised charging rate.
- Anker says this model does not support charging M2 MacBooks through Apple's MagSafe cable and recommends a USB-C-to-USB-C cable. Compatibility may differ across MacBook generations and cable revisions, so this limitation should be checked for the intended setup.
- High-output GaN chargers can become noticeably warm. An independent reviewer reported substantial warmth during MacBook fast charging; the charger should remain uncovered and ventilated.
- A charging cable may not be included in every retail package. Anker's standard product-page package list omits a cable, while some Amazon bundles have been advertised with one. Verify the exact seller and bundle before ordering.
- The charger's weight and protruding wall-mounted design may make it less secure in worn or loose receptacles than a lighter adapter. The reviewed evidence does not establish outlet retention across different receptacles.
- Adding or removing devices may cause USB charging negotiations to restart. The duration and behavior were not consistently documented for this model in the strongest sources reviewed.
