This is the early version of Ledger Nano X and Its like a USB drive that connects to any USB port. It doesnt have a battery and only starts up when plugged into a computer (or mobile device).
The Ledger doesnt come with an anti-tampering sticker as its cryptographic procedure checks for the integrity of the instrument when powered on.
It also comes with an OLED screen and two side buttons for confirming transactions.
When you configure your Nano S as a new device, you need to set up your pin code in order to secure your wallet. After that, note down and store your 24-word recovery phrase. This recovery phrase can be used anytime to restore your bitcoins.
With this wallet, your private keys are stored offline, so you need not worry about the safety of your coins.
Nano S is also the cheapest multi-currency hardware wallet ($90).
