The Anker 737 is a high-wattage USB-C power bank aimed at thin laptops on the road, not a featherweight phone brick. It can charge a modern laptop and still top up a phone. The display is the quiet win. You see input, output, and remaining charge without guessing.
Owners who travel with USB-C laptops usually care about real wattage at the port, not marketing slides. Cable quality decides whether the bank feels fast or defective. Weak cables at high wattage create fake “broken bank” returns. Pack a cable rated for the power you expect.
Capacity is large. So is the weight. Around 630g puts this in a backpack, not a jeans pocket. Phone-only travelers resent that by day two. If you only charge earbuds and a phone, a slim PowerCore-class bank is less to carry and costs less.
Hotel desks with one socket behind the bed are natural habitat. Trains and gates are the other. Airline watt-hour limits still apply. Check the printed Wh rating before you fly and keep the label readable. That advice shows up in every serious travel-gear thread for a reason.
If you already carry a 65W GaN wall charger, the bank is mainly for segments with no outlet at all. Recharge time into the bank itself matters too. Pair it with a wall brick that can fill it quickly when you finally find power.
Praise: laptop top-ups, clear display, multi-device charging, brand familiarity. Complaints: bulk, weight in a sling, cable dependency, overkill for phone-only kits. The product is coherent if you match it to laptop travel days.
Get the 737 for travel days with a thin laptop and no seat power. Skip it for pure phone use. Some laptops also charge slowly on USB-C no matter what the bank can do, so check both sides of the cable. Based on published specs and common Amazon and travel-forum themes, not a Second Week lab loan.
