Anker Nano 10K 45W: A Power Bank for People Who Forget the Cable

If your usual travel mistake is packing the power bank but forgetting its cable, the Anker Nano A1638 addresses that directly. Its retractable USB-C cable stays with the 10,000mAh bank. The draw is less to carry and manage, rather than the 45W headline. Anker specifications

What changes when the cable is built in?

Anker specifies an approximately 2.3 ft retractable USB-C cable, plus a separate USB-C port and USB-A port. That makes a quick phone top-up simpler when you are out for the day. TechRadar’s reviewer also found the cable and status display practical in use. That is their observation, not a Protein Picks hands-on test. Anker specifications TechRadar review

Can it charge several devices at full speed?

No. Anker rates the cable or USB-C port at up to 45W when used alone, and USB-C input at up to 30W. Use the cable and USB-C port together and total output falls to 22.5W; using all three outputs also has a 22.5W total limit. The 45W figure is a single-connection ceiling, not a promise of sustained output. Anker specifications

TechRadar reported that its test unit reduced power as it warmed and was less suitable for high-power devices. Treat this as a convenient phone-focused bank with some flexibility, not a substitute for a larger laptop power bank. TechRadar review

Who should skip it?

Skip it if you primarily need long, high-power laptop charging or expect full speed from multiple outputs at once. If you already carry the right cable and mostly care about battery capacity, the built-in cable may not justify choosing this model.
