Skil Power Core 20 2Ah: A Tool Battery That Doubles as a 100W Power Bank

Introduction

There are plenty of power tool battery brands on the market, and most of them follow the same formula: a rectangular pack, some charge indicators, and nothing else to get excited about. Skil’s new Power Core 20 2Ah battery breaks that pattern in a way that caught a lot of attention when it first appeared, and for good reason. It works as a regular 20-volt tool battery, but it also doubles as a genuinely fast portable power bank.

The Standout Feature: 100-Watt USB-C Output

The headline feature sits right on the front of the pack: a USB-C port rated for up to 100 watts of output. Skil’s earlier 12-volt batteries already offered a USB port for topping up a phone, but those were limited to around 5 or 10 watts, which made them painfully slow. The Power Core 20 changes that completely.

In real use, that 100-watt ceiling is more than most phones can draw. A phone charging at 18 or 19 watts barely makes this battery work hard, and anything faster you plug in simply gets the power it asks for. Even a laptop can be charged from it, which puts this in territory most portable power banks never reach.

If you have ever wished your tool battery could keep your devices alive during a power outage or a long day on site, this is exactly the use case Skil designed for.

Charge Indicators and Everyday Handling

Skil kept the battery simple to read. A green pulsating light on the side shows when the pack is charging, and a button on the front gives you a quick check of how much charge is left. The same indicator behaviour applies when power is flowing out of the USB-C port, so you always have a sense of what the battery is doing.

The small details add up here. A braided USB-C cable with connectors on both ends is a natural companion, since it plugs straight into wall outlets on one end and into your phone or laptop on the other.

Charging the Battery Itself

You get two ways to refill the pack. On the back there is a USB-C input, so you can charge it from a wall plug; Skil includes a 45-watt wall adapter for this purpose. The pulsating green light confirms it is taking in power.

Alternatively, you can drop it onto your standard Skil 20-volt charger like any other tool battery, which is handy if you already own Skil tools and keep a charger on the bench.

It Still Works as a Real Tool Battery

None of the power bank features get in the way of the primary job. This is still a 20-volt Skil battery, so it slides into compatible Skil tools and powers them normally. That dual role is what makes it such a clever design: one pack covers your drill and your devices.

At a price of around $75, it undercuts many dedicated high-wattage power banks while doing double duty as a tool battery.

Who Should Buy It

This battery makes the most sense for two overlapping groups. First, Skil 20-volt tool owners who want to consolidate: one fewer gadget in the bag, since your spare battery can now charge your phone or laptop. Second, anyone who wants a compact, genuinely fast power bank and does not mind that it comes in tool-battery form.

With 100-watt output, a 45-watt wall adapter included, and the ability to charge through either USB-C or your existing Skil charger, the value proposition is easy to understand. It is one of those ideas that seems obvious once you see it, and hard to go back from once you have used it.

Conclusion

The Skil Power Core 20 2Ah is a rare example of a tool battery accessory that adds real, everyday value instead of a gimmick. Fast 100-watt charging for your devices, simple charge indication, flexible recharging options, and full compatibility with Skil’s 20-volt tools make it an easy recommendation for Skil owners and a surprisingly compelling power bank for everyone else.
