The Slim Folio charges through a USB-C port on the bottom edge of the case

The Logitech Slim Folio is a keyboard case for iPad that has a built-in rechargeable battery. You charge it the same way you charge most modern devices: by connecting a USB-C cable to the port on the bottom of the case and plugging the other end into a power adapter.

The USB-C port sits along the bottom edge, usually centered or slightly toward one side depending on which iPad model your Slim Folio is designed for. You'll see a small rectangular opening — that's where the cable goes. The case doesn't have a separate charging dock or proprietary connector, so any USB-C cable and power adapter will work.

A full charge typically takes two to three hours with a standard 5-watt adapter (the kind that comes with many phones). If you use a higher-wattage adapter — say 20 watts or more — it may charge slightly faster, though the case's internal circuitry prevents overcharging.

Key Takeaways

  • The Slim Folio charges via USB-C, the same standard port found on most modern phones and tablets.
  • Any USB-C cable and power adapter will work; you don't need Logitech's specific charger.
  • A full charge takes roughly two to three hours with a standard adapter.
  • The battery typically lasts three to four months of normal use before needing a charge.
  • The case will not charge your iPad — it only powers the keyboard itself.

Where to find the charging port

Look at the bottom edge of the Slim Folio while it's closed. The USB-C port is a small rectangular opening, usually recessed slightly into the plastic. It's positioned to stay accessible even when the case is folded back or propped up for typing.

If you're having trouble locating it, check the user manual that came with your case — it will have a diagram showing the exact location for your specific iPad model. Logitech makes Slim Folios for different iPad sizes (standard iPad, iPad Air, iPad Pro), and the port position varies slightly between them.

What cable and adapter to use

Any USB-C to USB-C cable works. You likely already own one if you have a modern Android phone, recent iPad, or other USB-C device. The cable doesn't need to be made by Logitech.

For the power adapter, use whatever you have on hand — a 5-watt phone charger, a 20-watt laptop charger, or anything in between. Higher wattage won't damage the case; the charging circuit inside regulates the power automatically. If you don't have a USB-C adapter, you can buy a basic one for $10 to $20 from most electronics retailers.

Avoid using a damaged or frayed cable, as this can cause charging problems or pose a safety risk. If your cable is visibly worn, replace it before charging.

How to know when the case is charging

When you plug in the USB-C cable, you should see a small LED light on the case itself — usually on the front or side — turn on or change color. This light indicates the battery is receiving power. The exact behavior depends on your model: some cases show a steady light while charging and turn it off when fully charged, while others pulse or change from one color to another.

Check your manual for what the light means on your specific model. If you plug in the cable and see no light at all, try a different cable or adapter first — the problem is usually a faulty cable rather than a broken case.

Battery life and charging frequency

The Slim Folio's battery lasts roughly three to four months on a single charge with typical daily use. "Typical" means a few hours of typing per day. If you use the keyboard constantly, you may need to charge it every month or two. If you use it occasionally, you might go six months or longer.

You don't need to wait until the battery is completely dead to charge it. Charging whenever it's convenient — even if the battery still has 50 percent left — won't harm the battery or reduce its lifespan. Modern lithium batteries, which the Slim Folio uses, actually last longer if you avoid letting them drain completely.

Troubleshooting charging problems

If the case won't charge, start with the cable. Swap in a different USB-C cable if you have one available. Many charging problems are caused by a damaged cable rather than a broken case. If a different cable works, the original cable is faulty and should be replaced.

Next, try a different power adapter. A faulty adapter can prevent charging even if the cable is fine. If you have access to another USB-C power source — a friend's phone charger, a computer with USB-C, or a public charging station — test with that.

If the case still won't charge with multiple cables and adapters, the charging port itself or the internal battery may be damaged. At that point, contact Logitech support or check whether your case is still under warranty. Logitech typically covers manufacturing defects for one year from purchase.

Charging while using the keyboard

You can use the keyboard while it's plugged in and charging. The cable won't interfere with typing, though depending on how you position the case, the cable might get in the way of your hands or the iPad screen. Most people find it easier to charge the case when it's not in active use, simply to avoid the cable getting tangled or pinched.

The case will continue to charge even while you're typing, so if your battery is low and you need to use the keyboard right away, plugging it in won't stop you from working.

Frequently Asked Questions

Can I charge the iPad through the Slim Folio?

No. The Slim Folio only charges itself; it does not pass power to your iPad. You'll need to charge your iPad separately using its own USB-C port and charger. The case and iPad have independent batteries.

What happens if I leave the case plugged in overnight?

Nothing harmful. Once the battery is fully charged, the charging circuit stops delivering power to prevent overcharging. You can safely leave the case plugged in for hours or overnight without damaging the battery.

Does the Slim Folio come with a USB-C cable?

Most Logitech Slim Folios do not include a cable in the box. You'll need to provide your own USB-C cable and power adapter. If your case did come with a cable, use it, but you're not required to — any USB-C cable will work.

How do I know if the battery is fully charged?

The LED light on the case will change behavior when fully charged — usually turning off, stopping a pulse, or changing to a steady color. Check your manual for the exact indicator on your model. You can also try using the keyboard; if it responds normally, the battery has charge.

Can I use a fast charger with the Slim Folio?

Yes. Fast chargers (20 watts, 30 watts, or higher) are safe to use. The case's internal circuitry regulates the power, so a high-wattage adapter won't overcharge or damage the battery. Charging may be slightly faster, but the difference is usually small.
