Short answer: you don't strictly need one, but you should get one as a backup. At many fast chargers in Ireland you can simply tap your bank card, no fob required. But at older and slower chargers — and sometimes when an app won't connect — a charge card or fob is what gets you charging. So the honest advice is: you can start without one, but you'll want one in the glovebox before long.
This page explains what a fob actually is, when you'll need it, which one to get, and the setup catch that trips people up.
First, what is a fob?
A fob (also called a charge card) is a small plastic tag the charging company posts out to you, linked to your account with them. You tap it on the charger to start a charge — and that's the key thing to understand: a fob is not a way of paying. It's a way of starting the charger. The money still comes from the bank card or account you've linked to it.
That's different from your payment card — your ordinary bank Visa, Mastercard, or debit card — which you tap to pay, just like buying groceries. Two different cards, two different jobs. Mixing them up is the single most common source of confusion for new EV drivers, so it's worth keeping straight:
- Payment card = your bank card. Tap to pay. No setup.
- Fob / charge card = a free tag from the charging network. Tap to start. Needs setting up in advance.
So when do you actually need one?
You can manage without a fob if you only ever use newer, faster chargers that take a contactless tap. But you'll run into trouble without one in three common situations:
At older and slower chargers. Many of the slower on-street and car-park chargers (and a lot of older fast ones) don't have a contactless reader at all. At these, tapping your bank card simply does nothing — you need an app or a fob to start.
At ESB's standard chargers. This matters because ESB is the biggest network in Ireland. On ESB's standard and many fast chargers, a payment-card tap won't work — contactless only works at their newest High Power units. So if you rely on ESB at all (and most Irish drivers do), a fob or the ESB app is close to essential.
When an app won't connect. Some chargers sit in underground car parks or low-signal spots where your phone can't reach the network app to start a charge. A fob can work where an app can't, because it doesn't depend on your phone having signal. This is the quiet reason experienced drivers keep a fob even when they mostly tap their card.
Which fob should you get?
If you're going to carry one fob, the EZO fob is the most useful single option in Ireland. Here's why: tapping the EZO fob doesn't only work at EZO's own chargers — it also starts and pays at ESB and Ionity chargers on the one EZO account. That's three of the networks you're most likely to meet, including the ESB chargers where a bank-card tap so often fails. One fob, the widest local reach.
The free ESB charge card is also well worth having alongside it, especially if you'll use ESB a lot. On ESB's own chargers, the native ESB card is the most dependable option of all — there's no "roaming" step that can occasionally hiccup. It's free, so there's little reason not to have both: the EZO fob for reach, the ESB card for rock-solid reliability on the biggest network.
If you'll charge abroad as well, a free Octopus Electroverse card is a good extra — it works across most networks in Ireland and right across Europe with no subscription. It's less well known here, so think of it as a useful add-on rather than your first choice.
One network a fob won't help you with: Tesla Superchargers. Those work only through the Tesla app, and no third-party fob or card will start them.
The catch nobody mentions: setup and balance
Here's the part the charging companies tend to gloss over. A fob isn't a tap-and-go solution out of the box. Before it works, you usually have to:
- Order it in advance and wait for it to arrive in the post — so it won't rescue you on your first day.
- Link it to a payment card, or load it with credit. Some networks (including ESB on pay-as-you-go) require a minimum balance before the fob will start a charger — for ESB that means an initial top-up and keeping at least €5 on the account.
One EZO-specific rule is worth knowing, because it catches people out: EZO requires a minimum €20 balance before any charge will start — even for a small charge. Below that, the charger simply says "declined," which looks like a broken fob but is really just the balance rule. Keep at least €20 on the account and it won't happen. (The EZO activation box below has the details.)
So the right way to think about a fob is as a backup you set up before you need it — not something that helps you in the moment you first get stuck. Order it early, link or top it up, drop it in the glovebox, and forget about it until the day a charger won't take your card.
The simple recommendation
For most Irish drivers:
- Use contactless (your bank card) as your everyday method at fast chargers that take it.
- Get one EZO fob as your main backup — it reaches EZO, ESB, and Ionity from a single account.
- Add the free ESB charge card too, for the most reliable charging on the biggest network.
Do that once, and you're covered at almost every charger you'll meet — tapping your card where you can, and reaching for a fob only when you need to.
