Our take on the Portable Charger 20000mAh Power Bank 22.5W Fast Charging Battery Pack

A 20,000mAh USB-C power bank with 22.5W fast charging, PD 3.0 and QC4+ support, built-in cables and a digital display. It weighs 430 grams and measures 7x3x1 inches, so it is a bag charger rather than a pocket one. It has no wireless charging and no solar. At $20.97 at Walmart as of November 5, 2026, it is a low price for this capacity and wattage.

Questions and answers

Is this power bank worth it at $20.97?
Yes, if you want maximum capacity for the money. 20,000mAh with 22.5W PD/QC charging at $20.97 at Walmart as of November 5, 2026 is cheap for this class. You trade pocketability for capacity.
How many times can it charge a phone?
Roughly 4 to 5 full charges for a typical 4,000-5,000mAh phone, less in practice because of conversion losses. Expect around 3 to 4 real-world charges.
Can it charge a laptop?
Only slowly. The 22.5W maximum output is below what most laptops need for normal charging, so it suits phones, tablets and earbuds rather than laptops.
Does it support fast charging on iPhone and Samsung?
Yes. It lists PD 3.0 and QC4+, which cover USB-C iPhone fast charging and Samsung fast charging, provided you use a compatible cable and port.
What is in the box?
The power bank with built-in cables, including a Micro USB input cable. A separate wall adapter is not listed, so plan to supply your own charger for recharging it.
How long does it take to recharge?
Several hours. The input is listed at 12V/1.5A max, so a full recharge from empty takes roughly 5 to 7 hours with a suitable adapter.
Where is the Portable Charger 20000mAh Power Bank 22.5W Fast Charging Battery Pack cheapest?
At Walmart, for $20.97, as of our latest check.
