The Baseus Blade ultra-slim power bank is back at its lowest Amazon price yet, and this time you don’t need a Prime membership to take advantage of it. If you’ve been looking for a travel-friendly portable charger that can handle everything from phones to laptops, the Baseus Blade 20,000mAh model is getting attention again thanks to a price that drops to just under $40 when you apply the coupon code CAXWUTQ9 at checkout (availability and pricing can change quickly).
What makes the Baseus Blade stand out isn’t that it has the biggest battery on the market in 2025—it’s the design. This is a super-slim power bank built for people who actually carry gear every day. At only about 0.7 inches thick, it’s slim enough to slide into a laptop sleeve or backpack pocket without adding that bulky “brick” feeling most high-capacity chargers come with. It measures roughly 5.28 x 5.28 inches and weighs around 1.08 pounds, which helps explain why it’s often compared to the footprint of a small tablet rather than a traditional power bank.
In terms of charging capability, the Baseus Blade offers a 20,000mAh capacity, which should provide multiple full charges for most smartphones. It’s also a useful backup for laptops, where it can add a few extra hours of work or streaming time when you’re away from an outlet—especially valuable for commuting, travel days, conferences, and campus life.
A big reason this model remains popular is its port selection and power output. You get four output ports in total: two USB-C ports and two USB-A ports. The USB-C ports are rated for up to 100 watts each, making the Blade a strong option for USB-C laptops and other devices that benefit from higher-wattage charging. The USB-A ports are rated up to 30 watts each, which is still plenty for phones, accessories, and many tablets.
One thing to keep in mind is that the maximum output changes depending on how many ports you use at the same time. Reviews note that the shared output behavior can be a downside if you’re trying to fast-charge several devices at once, because performance can drop when everything is plugged in together. For many buyers, though, that’s a reasonable trade-off for the Blade’s signature feature: a thin, packable shape with enough power to cover both phone charging and laptop top-ups.
If you’ve been waiting for a solid deal on a slim 100W power bank, this is one of the better price drops seen for the Baseus Blade. Since Amazon discounts and coupon offers can disappear fast or run out of stock, it’s worth checking sooner rather than later if the Blade’s portability-focused design fits your everyday carry setup.
