Best Prices Today: INIU Cougar P64 140W Power Bank
$79.98
- Who is the INIU Cougar P64 for? This power bank is rated at 140W for 16-inch MacBook Pro fast charging but is a good-looking battery recharging solution for any MacBook owner, from the Neo up.
If you’re away from a power socket long enough even a fully charged MacBook battery will eventually dry up, and that might be in the middle of a complex Excel spreadsheet, deep PowerPoint or just as the streamed movie is getting good.
We’re used to carrying around a power bank for our phones—check out the best magnetic power banks for iPhone—but lugging one around that’s big enough to top up a thirsty laptop is not an everyday backpack companion.
When you’re travelling having a high-capacity power bank nearby might just save that spreadsheet or presentation and get you to the end of the movie.
Laptop power banks come in different capacities—the higher the milliamp hours or watt hours the more recharge power it brings—and at different speeds: the more watts, the faster the charge.
We loved INIU’s Cougar P62-E1 laptop power bank for its lightweight compact form and fun color choices in a world of gray pillar designs. That model topped out at a 65W power output—just about enough watts to fast-charge a MacBook Air but falling a little short for a MacBook Pro. It can handle the Pro but a little slowly.
Now it has a senior sibling, the Cougar P64 that is rated at PD 3.1, which means its Power Delivery is up to the 140W demanded by the 16-inch MacBook Pro for fast-charging. It will work at the max speed of all Apple’s other MacBooks, too.

Macworld Test Score: 119%
It’s the slimmest and lightest of all the 140W laptop power banks we’ve tested, and maybe the best looking depending on whether you prefer the slab shape compared to its rivals’ pillar form.
It ships with a 2-foot 240W USB-C to USB-C cable and a handy travel pouch. It’s available in either black or white, although the white model was hard to get at the time of writing.
The EcoFlow RAPID Pro Power Bank has an integrated USB-C cable that is convenient, especially if you are susceptible to forgetting to pack a cable on your travels.
Fastest charging
With a 140W USB-C port, the INIU Cougar P64 matches the speed of some of our other top-rated MacBook power banks, including the Anker Prime Power Bank (26K, 300W), EcoFlow RAPID Pro Power Bank 27K (300W), Ugreen 48000mAh Portable Power Bank (300W), Cuktech 15 Ultra Power Bank 20000mAh (165W) and others.
At top-speed it should take only 30 minutes to simultaneously charge a 16-inch MacBook Pro to 60% and an iPhone 15 Pro Max to 62%. It also supports Samsung Super Fast Charge 2.0.
25K capacity and performance
Its large 25,000mAh (92.5Wh) battery capacity is airline-approved, although it’s always worth checking before taking it to the airport as some airlines have their own rules.
In our recharging test, the INIU Cougar P64 got a Macworld score of 119%. That means that it recharged our test 14-inch MacBook Pro from 0% to 100% and then another 19% on the second recharge.
That compares favorably with the Anker Prime’s 125% and EcoFlow’s 120% scores.
Max output
Where it falls off in comparison to its rival 140W power banks—and therefore where you must compromise fir the lower cost—is its lower maximum power output. Using its two USB-C ports it can push out a total of 145W (100W+45W), where the Anker Prime, Ugreen 48000mAh and EcoFlow RAPID Pro each has a maximum 300W output.
If you are wanting to recharge a few MacBooks at the same time, the P64 will do it slower than the others as it has less power to simultaneously share around.
That said, when using all three at the same time, one laptop could be charged at 100W with the other two ports sharing 45W, which should be enough to fast-charge an iPhone (via the second USB-C) and a third device via the USB-A port.
Input
The P64 is no slouch when it comes to being recharging itself, with an 80W input speed. But the Anker Prime and EcoFlow Power Banks can use both their two 140W ports at the same time for far-higher input speeds of 250W and 280W respectively.
If time is on your side before you venture out, 80W should be fast enough for a gentle power bank recharge.

Display
The P64 has a large smart display, showing the remaining power in the power bank, the output power of each port, plus the remaining battery in terms of hours.
Price
How does the INIU Cougar P64 match up on price with its 140W rival power banks?
Priced at $89.99 / £89.99 it looks like a bargain compared to the $229/£179 Anker Prime and $189/£169 EcoFlow RAID Pro. Those products have higher total power output when using more than one port at a time and much faster power bank recharging, but for a fast-charging laptop power bank the P64 is hard to ignore at this price.
The Cuktech 15 Ultra is cheaper still at around $75 but has a lower 20K battery capacity and a larger body.
Should you buy the INIU Cougar P64 140W 25K Power Bank?
The Cougar P64 is a compellingly affordable power bank for MacBook owners with its speedy recharging and compact, lightweight form.
