Which is better for charging a laptop?

The Prime 20K (220W). It delivers 140W over USB-C and charges a 16-inch MacBook Pro (M4 Pro) to 50% in about 28 minutes. The 65W model tops out at 65W, too low for fast laptop charging.

How many phone charges do I get from each?

The 20K's 20,100mAh is rated for up to 4.2 days of video streaming on an iPhone 17 Pro Max. The 65W's 9,600mAh is roughly a single day of heavy phone use.

Is the 20K worth the extra money?

Yes if you charge a laptop or several devices at once. If you only charge a phone, the 65W covers it and is easier to carry.

Can I take either on a plane?

Both are flight-approved. The 20K is 72.36Wh, under the 100Wh carry-on limit, and the 65W is smaller still.

How fast does each recharge?

The 20K reaches 50% in about 25 minutes on its 100W USB-C input. The 65W takes about 2 to 2.5 hours.

Do both have an LED display?

Yes. Both list an LED display; the Wukong Edition adds custom UI animations tied to its charging indicators.
