Summary

A single-port 20W USB-C Power Delivery wall charger for phones and small tablets, sold under Anker’s PIQ 3.0 label. Check whether your phone needs PPS fast charging before you buy: this charger has no PPS, so it will not trigger Samsung Super Fast Charging and charges PPS-only phones slowly.

Strengths

  • One USB-C port, 20W maximum, and a footprint of roughly 30 mm per side.
  • Delivers close to its rated output: a lab test of the sibling A2149 measured 19.76 W on the 9V rail.
  • Charges an iPhone 13 to 50% in 27 minutes, matching Anker’s own claim.
  • Small and light enough to live in a travel bag.
  • Anker’s 18-month warranty on this family is longer than most commodity chargers.

Weaknesses

  • No PPS, so Samsung Super Fast Charging will not engage and PPS-only phones charge slowly.
  • A single port, no USB-A, and no cable in the box.
  • At sustained load the sibling unit reached 61.3 °C surface temperature, so it should not be covered while charging.
  • One owner reported the Cube negotiating 12V at 1.55–1.6A instead of the advertised 9V at 2.22A.

Charging speed and output

Anker’s own manual for the A2637 specifies 100–240V input at 0.6A and USB-C output of 5V at 3A or 9V at 2.22A, which matches the seed product’s published spec. No instrumented test of the exact seed unit exists. The closest measurement is a lab teardown of the sibling A2149 Cube: a protocol decoder confirmed exactly the two advertised profiles, 5V at 3A and 9V at 2.22A, with no 12V and no PPS, and the 9V rail delivered 19.76 W (8.94V at 2.21A, 98.8% of its profile) while the 5V rail delivered 15.02 W. An iPhone 13 reached 50% in 27 minutes and 100% in 1h 37m. Android Authority measured 18.7 W reaching an iPhone 13 from the PowerPort III Nano, and only 14.3 W to a Samsung Galaxy S21 because the charger lacks PPS.

Ports, cable and design

The charger is a cube roughly 30 mm per side and about 30–31 g, and it ships without a cable, so you need your own USB-C cable. There is one USB-C port and no USB-A, and the prongs are fixed rather than folding on at least some variants, which reviewers call a portability negative. TechRadar’s UK review of the PowerPort III 20W reports 20W maximum, one USB-C port, dimensions of 49 × 45 × 33 mm with the UK adapter, and a £11.99 street price, and calls it a weak choice in a crowded field.

Repairs, warranty and running costs

The device is a sealed adapter with no user-serviceable parts, so a fault means replacement rather than repair. Anker’s manual for the A2637 documents normal operation and FCC compliance but lists no serviceable components. Warranty coverage varies by SKU and channel: Anker’s retail listings state 18 months for the PowerPort III 20W family, while the Anker US store states 12 months on some 20W multi-packs. The only running cost is a USB-C cable if you do not already own one. At sustained load the sibling unit reached 61.3 °C surface temperature, so keep it ventilated while it charges.

Is it worth it?

At about $10–12 this is a fair, unexciting commodity charger for one phone that accepts 20W USB-C PD. Anker US lists the Nano Charger (20W) at $11.99, and a US marketplace listing for the Anker USB C Charger Block 20W (Nano Pro) shows $11.99, with a Glacier Blue color at $9.99. Anker Singapore lists the A2149 at a $17.99 regular price. Below about $8 it is strong value; $13–16 is weak for a 20W brick, and above $16 a single-port 20W charger is not recommended. If your phone wants 25W or more with PPS, or you want folding prongs and a second port, a higher-wattage PPS-capable charger is the better value.

Which model this is

This page covers the 20W single-port Anker USB-C charger sold under the PIQ 3.0 label; the listing’s ASIN is B08N68K4TP. The exact ASIN-to-model mapping is unresolved: Anker’s A2637 manual gives the electrical spec that matches the seed (0.6A input, 5V at 3A, 9V at 2.22A), while the seed’s 28 × 28 × 30 mm and 30 g sit between the A2637 (29.5 mm, about 31 g) and the A2633 PowerPort III Nano (30 g). The A2149 PowerPort III 20W Cube is a separate foldable model at 42.1 g with 0.7A input. Match the model number before you buy.
