Verdict up front: the Ellipal Titan 2.0 is the most physically uncompromising air gap you can buy — a sealed, full-metal slab with no data ports at all: no USB data, no Bluetooth, no WiFi, no NFC. Transactions pass exclusively as QR codes through the glass, and prying the case open wipes the keys. It’s a fortress at $169 — with a vault door we can’t see behind: the key-generation code is closed, which caps it at 4/10 on our verifiability board. The $79 X Card is the featherweight sibling: a tap-to-sign card in the Tangem mold. Both weighed honestly below.

The fortress philosophy
Every air-gapped wallet promises isolation; the Titan 2.0 builds it. Where a Keystone or Coldcard still has a USB port (power and, on some, data modes) and a microSD slot within reach, the Titan is a sealed metal unibody whose only conversation with the world is light: QR codes shown and scanned through the glass. Firmware updates arrive by microSD through a detachable adapter, USB-C is power-only, and the tamper response is the same promise SafePal and Keystone make — open the case, lose the keys — wrapped in a chassis that feels like it could stop a car door. For the physical-threat-model buyer (border crossings, hostile roommates, burglary-prone areas), nothing else in this price class is built like it.
The closed door
Here’s the tension our scoring can’t ignore: the strongest physical isolation in the roundup is guarding code we can’t fully read. Ellipal’s firmware is only partially open, and critically, the key-generation code is closed — the single most important routine in any wallet, the one that decides whether your entropy is truly random, is a trust-us. No published breach suggests a problem, audits exist, and the QR protocol is inspectable in transit — but at the same $169, a Trezor Safe 5 ships fully open firmware, and at $149 a Keystone publishes even its secure-element code. On our pillars that’s the difference between 4/10 and 8+/10. Fortresses are wonderful; we just prefer ones with published blueprints.
The X Card, briefly and fairly
The X Card competes with Tangem: a secure-element card you tap against your phone to sign, no battery, no screen, wallet lives in the app’s UI. It’s a fine $79 “always in the wallet” device with one structural caveat shared by all screenless cards: you verify transactions on your phone’s screen, which is precisely the machine a hardware wallet exists to distrust. For meaningful sums, buy something with its own display; for pocket money and gifting, the format is genuinely convenient.
Who should buy it — and who shouldn’t
- Buy the Titan 2.0 if: your threat model is physical — theft, tampering, coercion — and you want the most sealed device made; you’re comfortable trusting Ellipal’s closed key-gen the way Ledger owners trust theirs.
- Buy the X Card if: you want a no-battery spare or a starter card and accept phone-screen verification (see also our Tangem row).
- Skip both if: verifiability drives your choice — the Keystone 3 Pro gives you the air gap with receipts, and the Safe 5 gives full transparency at the same price as the Titan.
FAQ
How do firmware updates work with no data ports?
Via microSD card through the included adapter — you download the update on a computer, move it on the card, and the device verifies and installs it offline. Slightly ceremonial, entirely in keeping with the philosophy.
Is QR-only signing limiting day to day?
It’s the same loop as a Keystone: build in the app, scan, verify on the Titan’s 4-inch screen, sign, scan back. A few seconds slower than Bluetooth; several philosophical miles safer.
If the tamper-wipe triggers, are my coins gone?
No — the device is gone; your coins live on your seed backup. Which should be steel: our guide.
Bottom line
The Titan 2.0 wins the physical-security arms race outright — sealed metal, zero radios, self-wiping. If the wallet-in-hand is your worry, it’s the pick. If the code-in-wallet is your worry, the same money buys published source elsewhere, and that’s where our score lands: respect for the fortress, points withheld for the blueprints.
