The iWalk KS1 Pro 2021 was a visionary product. It predicted the rise of "dockable" batteries before the MagSafe boom. Today, it faces stiff competition from magnetic wireless batteries (like Anker MagGo). However, the KS1 Pro has two distinct advantages over magnetic batteries:

In the fast-paced world of personal mobility, finding the perfect balance between portability, power, and price can feel like an impossible quest. Enter the iWalk KS1 Pro 2021—a third-generation electric scooter that redefines what a lightweight commuter vehicle can be. Building on the successes (and learning from the limitations) of its predecessors, the 2021 Pro model isn’t just a minor refresh; it’s a complete overhaul of the ultra-portable scooter category.

I have spoken to users who have had the KS1 Pro 2021 since its launch. The most common failure point is not the battery (lithium holds up well), but the hinge mechanism.

If you drop the power bank while it is attached to your phone, the leverage force can snap the plastic hinge. However, under normal use—tucking it into a purse or a laptop bag—the mechanism remains solid. The battery degradation after two years is typical: expect about 80-85% of the original capacity.

Let’s address the elephant in the room: 7.5W output.

In 2021, this was considered "standard fast charging" for iPhones. By 2025 standards, it is slow. However, we need to contextualize what the KS1 Pro is designed for. This is not a fast charger. It is a top-up charger.

It cannot keep an iPhone 15 Pro Max alive while gaming, but for social media, music streaming, and navigation, it provides a steady, low-heat trickle charge. Heat is the enemy of lithium batteries, and because the KS1 Pro charges slowly, your phone stays cool.

Unboxing the KS1 Pro 2021, the first thing you notice is the weight—or rather, the lack thereof. Tipping the scales at just 26.5 lbs (12 kg) , this scooter is featherlight in a market dominated by 30–40 lb behemoths. The matte black aerospace-grade aluminum frame feels rigid and premium, with zero creaks or flex. The new 2021 folding mechanism—a one-lever, secondary safety-lock system—snaps shut with a reassuring click, allowing you to carry it onto a bus, train, or up three flights of stairs with one hand.

First, let’s clarify the nomenclature. The "2021" model is a specific revision of iWalk’s popular KS1 series. Unlike generic rectangular power banks, the KS1 Pro looks like a futuristic lipstick case or a small Bluetooth speaker.

Its defining feature is the integrated Lightning connector (and a separate USB-C version) that flips out from the top. Essentially, it plugs directly into the bottom of your phone—no cables required. This turns your phone into a slightly taller, heavier device, but one that is actively charging without any dongles.

The "Pro" in the name isn't just marketing. iWalk listened to user feedback from the 2019/2020 models and delivered three major improvements:
