Which charger for Oura Ring 5? The original in your ring size or a charging case

For the Oura Ring 5 you need the original Oura charger in exactly the same size as your ring. For trips, you can take a charging case, which also comes in ring sizes.

The charger from the Ring 4 does not fit, because the new one works only with the Oura Ring 5, and according to Trusted Reviews the old Ring 4 case does not work with the new ring because the design has changed.

The charger comes in the box with the ring, as the Engadget and Trusted Reviews reviews note. So this guide is about a second charger, for your desk or your bag, and about travel.

The Oura charger comes with a USB-C cable. According to Oura, the ring charges in 20-80 minutes, and on a full charge it lasts 6-9 days, depending on size and use. Tom's Guide gives up to 9 days for the Ring 5 and up to 8 for the Ring 4, Engadget about a week, and Trusted Reviews a result just under 8 days.

Charger size: where to check it and why it matters

The ring size is stamped on the inside. Look inside the ring and read it before you order anything.

The charger must be exactly the same size as the ring. It is not a universal dock, so a charger in a different size will simply be the wrong one.

Watch out for links in listings. The link in the box leads to one size, and you choose your own only on the listing page. Before you click "buy", check that the size you selected matches the one stamped in your ring.

Fun fact: according to Oura, 10 minutes of charging gives the ring a full day of use. If you forget to charge in the morning, a short break at the charger is enough to start the day.

We picked the original Oura charger and case, plus two third-party alternatives, so you can compare them.

Recommended chargers for Oura Ring 5

Charging case for travel: 5 charges without looking for an outlet

The Oura charging case is the size of a ring and gives up to 5 full charges from a single charge of the case. According to Oura, that's up to a month of ring use, so for a longer trip you can leave the charger at home.

The case itself charges wirelessly on a Qi charger or via USB-C. A USB-C cable is not included in the box, so if you don't have one handy, buy it together with the case.

It fits in a backpack pocket or a toiletry bag, with no extra luggage.

Fun fact: the case weighs 60 g and measures 56 x 55 x 17 mm, according to Oura. That's not much for a power reserve that covers this many charges.

Third-party alternatives and the power adapter: what they promise and what you risk

There are chargers from other companies on the market. XZ-Tech and Baiyexing state Gen 5 compatibility in individual sizes. ALAFLY is a 2000 mAh case for Gen 3, 4 and 5, into which you insert your own charger.

All of them are non-Oura products, so Oura's warning applies: unauthorized chargers can permanently damage the ring's battery. If you do reach for an alternative, treat it as a cheap backup at your own risk, and use the original every day.

A power adapter is not included. A regular USB-C adapter is enough, and Oura does not specify the required power, so you don't need to look for a special model.
