Baseus Blade 20,000mAh 100W Power Bank Hits Record-Low $39.99 at Amazon

Baseus Blade power bank hits record-low price

The Baseus Blade 20,000mAh 100W power bank is on sale for a record-low price of $39.99 at Amazon. You must apply coupon code YBKEIAQE at checkout to get the deal, which does not require an Amazon Prime membership.

This is a significant discount for a high-capacity, high-output power bank with a unique slim design. It’s powerful enough to fast-charge gaming handhelds and laptops.

A slim, wide design with four ports

Unlike most chunky, brick-shaped power banks, the Baseus Blade is just 0.7 inches thick. It achieves this by using a wider body design, making it easy to slip into a laptop bag or backpack sleeve.

It weighs about one pound, which is standard for its capacity. The wide body houses four charging ports.

• Two USB-C ports: Each supports 100W Power Delivery.
• Two USB-A ports: Each supports 30W output.

The total maximum simultaneous output is 100W, not the sum of all ports. If you use multiple devices, the bank will intelligently split that 100W of power between them.

Capacity for multiple device charges

The bank has a 20,000mAh (74Wh) battery. Factoring in about 80% power efficiency, here’s how many full charges you can expect for popular devices:

• Nintendo Switch 2 (18Wh): About 3.3 times
• Steam Deck (40-50Wh): About 1.2-1.5 times
• ROG Ally (60Wh): About 1 time
• ROG Ally X (80Wh): About 0.7 times
• Lenovo Legion Go (55Wh): About 1 time
• iPhone 17 (14Wh): About 4.2 times
• iPhone 17 Pro Max (20Wh): About 3 times

Fast charging for phones and handhelds

The 100W USB-C ports can deliver power at the maximum rate a connected device will accept. It automatically throttles down for devices that don't need the full wattage.

For example, a Nintendo Switch 2 would get 18W-30W, a Steam Deck would get up to 45W, and an ROG Ally X could take the full 100W. This makes it a versatile charger for nearly any phone, tablet, or gaming handheld.

TSA-approved for air travel

With a capacity of 74Wh, the Baseus Blade is well under the TSA's carry-on limit of 100Wh. You can bring it in your carry-on luggage without issue, making it a solid travel companion.

The sale price of $39.99 is a standout deal for a power bank with this combination of capacity, output, and portability. The coupon code is valid for Presidents Day.
