ANTANK B08

Most power banks disappear into a bag, along with a tangle of cables. The ANTANK B08 takes a different approach, treating the carrying method as a core feature. According to the maker, the unit can be held by a leather hand strap or slung across the body on a 1.6-meter strap, and that crossbody strap has a Type-C cable built into it.

Capacity and output

The maker says the 25,000mAh battery is enough to charge a smartphone 3–4 times or an iPad 2–3 times, and that it can also charge a laptop. Output is rated at 100W with PD 3.0 fast charging, which the maker claims can bring a device to 60% in 30 minutes. Two USB-C ports and one USB-A port allow three devices to charge at the same time.

A strap that is also a cable

The crossbody strap combines two zinc-alloy hooks with a 1.6-meter Type-C cable protected by braided wire, letting the bank charge a device while being worn hands-free. The cable is described as 60W. A silicone plug is included to keep dust out of the Type-C port. For business settings, the leather hand strap offers a more formal option.

Display, protection and design

• Smart display showing remaining battery percentage, estimated usage time and charging progress in real time
• Six-layer protection system covering risks including overcharging, over-discharging, overvoltage, short circuits and high temperatures
• Aluminum alloy body with what the maker calls a halo-style, minimal design

Taken together, the B08 pairs familiar power bank specifications with an unusual emphasis on how the device is carried, positioning the strap-integrated cable as its defining detail.
