Our take on the Baseus 20000mAh 45W Power Bank with Built-in USB-C Cables

A 20,000mAh power bank with two built-in USB-C cables, so you don't need to carry one. The USB-C port and cable output up to 45W with PD3.0, PPS and QC4+ support, enough to fast-charge most phones and many small laptops. An LED display shows remaining charge, and it can run four devices at once. At $26.99 at eBay as of November 4, 2026, it sits at the low end of its recent price range.

Questions and answers

Is 45W enough to charge a laptop?
It will slow-charge or maintain many USB-C laptops, but not at full speed. For a MacBook Air or similar low-power laptop it works as a travel top-up; for a 65W-plus laptop expect slow charging under load.
How many times can it charge a phone?
With 20,000mAh and typical conversion losses, expect about three to four full charges of a 4,500-5,000mAh phone. Heavier use and simultaneous charging reduce that.
How long does it take to recharge?
The USB-C input is 30W, so a full recharge takes roughly three to four hours with a 30W or higher PD charger. A lower-wattage charger will take longer.
Does it support Samsung Super Fast Charging?
PPS support means it can trigger Samsung Super Fast Charging (25W) on compatible Galaxy phones. It will not reach the 45W mode some Galaxy models use.
What's in the box?
The power bank with its built-in cables. A wall charger and a separate charging cable are not included, so you need your own USB-C charger for recharging.
Is $26.99 a good price?
Yes. At $26.99 at eBay as of November 4, 2026, it is near the bottom of its recent range for a 20,000mAh 45W unit with built-in cables.
Where is the Baseus 20000mAh 45W Power Bank with Built-in USB-C Cables cheapest?
At Amazon, for $29.97, as of our latest check.
Where can I buy the Baseus 20000mAh 45W Power Bank with Built-in USB-C Cables?
