Laptop power banks need to do more than top up a phone: they have to deliver enough sustained USB-C Power Delivery output to keep a laptop charging, in a size you will actually carry. Here we review and compare laptop power banks by output per port, capacity in watt-hours, cables, size, weight and warranty, using manufacturer specifications. Browse our roundups, single reviews, head-to-head comparisons and how-to guides below, and match the bank to the wattage printed on your laptop charger.
