737 PowerCore 24K Power Bank / Anker
The 737 is Anker's flagship power bank, built to be the one battery that charges everything fast. It holds 24,000mAh, enough for several phone charges or a meaningful top-up of a laptop, and pushes up to 140 watts out through USB-C, quick enough to run most ultrabooks at close to full speed rather than trickling. A small colour screen on the side reports charge level, wattage in and out, and estimated time remaining, replacing the guesswork of four blinking dots with actual numbers. It recharges itself quickly over USB-C too. It suits the traveller or remote worker who wants a single high-capacity battery for a phone and a laptop, and accepts that this much capacity and output makes for a heavy brick, close to the airline cabin limit, that is more than a phone-only user needs.
Design intent
- +The defining decision is to serve a laptop, not just a phone: 140-watt USB-C output is enough to fast-charge most ultrabooks, so one battery covers the whole kit rather than leaving the laptop tethered to a wall, which is what justifies the size.
- +The information display is a deliberate answer to the power bank's oldest weakness, not knowing what is left: a readout of exact charge, live wattage and time remaining replaces four ambiguous LEDs, so the user can actually plan around it.
Trade-offs
- -High capacity and high output make it heavy and bulky, and at 24,000mAh it sits near the 100Wh airline carry-on limit, so it is a deliberate trade of pocketability for power that a phone-only user does not need.
- -It is a sealed lithium battery whose cells fade over years of cycles and cannot be replaced, and reaching its full 140-watt speed needs a compatible cable and device, so the headline figure is not always the real-world one.
