Ultra-Slim Magnetic Power Bank

The Kuulaa KL-YD71 is a 5000mAh lithium-polymer power bank designed for MagSafe-compatible iPhones. It snaps onto the back of iPhone 12 through 17 series devices for cable-free charging. A USB-C port provides wired input and output for other devices. The aluminium shell measures 0.27 inches thick and weighs 110 grams.

Wireless And Wired Output Limits

Magnetic wireless charging delivers up to 20W when aligned with a compatible iPhone. The USB-C port supports 5V at 3A for both charging the power bank and powering connected gear. Metal objects, cards, thick cases or pop grips can weaken the magnetic hold and reduce wireless efficiency. Some capacity is lost during voltage conversion and wireless transfer.

5000mAh Capacity For Daily Top-Ups

The 5000mAh cell provides roughly 0.7 to 0.9 full charges for typical iPhone models depending on usage conditions. It can raise an iPhone 15 from empty to around 55 percent in 30 minutes via wired connection. Users needing multiple full phone charges or power for larger devices like tablets should consider a higher-capacity unit.

Questions about this item

Which version of the Kuulaa KL-YD71 should I choose for my iPhone?

The KL-YD71 comes in a single 5000mAh capacity with USB-C input and output, and magnetic wireless charging for iPhone 12 through 17 series.

What does the 5000mAh rating actually deliver to an iPhone in daily use?

Expect roughly 0.7 to 0.9 full charge for most iPhone models because energy is lost during voltage conversion and wireless transfer.

How fast does the USB-C port charge and what limits it?

The USB-C port supports up to 20W output, so an iPhone 15 can reach about 55% in 30 minutes; the 5V 3A rating caps the maximum speed.
