Best USB-C charger under $50

You are answering a consumer research question. Name your top 3 products, in order, with the exact product name and manufacturer. Judge each one on its specifications and measured results; do not copy a review site's ranking. If you are unsure, say so. Do not invent a product that does not exist. Prices are a constraint where stated; if a constrained pick does not exist, say that and give the closest honest alternative. This is not a paid placement.

    {
      "rank": 1,
      "product": "Anker 317 Charger (100W)",
      "manufacturer": "Anker",
      "reason": "Its specified 100W USB-C PD output and included 100W-rated cable offer the strongest laptop-charging value under $50.",
      "caveats": "Typically about $36–$40 in the U.S.; only one port, and independent measured performance is not verified."

      "rank": 2,
      "product": "Anker 523 Charger (Nano 3, 47W)",
      "manufacturer": "Anker",
      "reason": "Two USB-C ports provide a specified 27W plus 20W simultaneously, or up to 45W when charging one device.",
      "caveats": "Typically about $40 in the U.S.; cables cost extra, and independent measured performance is not verified."

      "rank": 3,
      "product": "Anker 313 Charger (Ace, 45W)",
      "manufacturer": "Anker",
      "reason": "Its 45W USB PD PPS support makes it a particularly good specification match for compatible Samsung phones.",
      "caveats": "Typically about $30 in the U.S.; Samsung's fastest charging requires a 5A cable, and independent measured performance is not verified."

{"knowledgeAsOf":"early 2025","picks":[{"rank":1,"product":"Anker 735 Charger (Nano II 65W)","manufacturer":"Anker","reason":"GaN charger with 65W USB-C PD from one port plus two more ports (2C+1A) in a compact foldable body, so it can charge a laptop, phone and earbuds from one brick.","caveats":"List price is about $50–60, so it is usually under $50 only on sale. Total output is shared when several devices are plugged in, so the laptop port drops below 65W."},{"rank":2,"product":"UGREEN Nexode 65W USB-C Charger (3-Port, 2C1A)","manufacturer":"UGREEN","reason":"65W PD/PPS GaN output with three ports, typically priced in the $35–45 range, making it the strongest multi-port value under $50.","caveats":"UGREEN sells several similarly named 65W Nexode models, so check the exact port layout. Power drops when ports are shared."},{"rank":3,"product":"Anker 715 Charger (Nano II 65W)","manufacturer":"Anker","reason":"Single-port 65W USB-C PD GaN charger that is small enough to fit in a pocket and enough to charge most 13–14-inch laptops, MacBook Air models and phones at full speed.","caveats":"It has only one port. Newer models such as the Anker Nano 65W may have replaced it in some stores."}]}
