Choosing car accessories without making a costly mistake: check these specifications

Car accessories range from a Type 2 EV charger and a jump starter to a USB-C fast charger or tools for changing tyres. The right choice depends on more than just price or power. The connection, electrical installation, compatibility and intended use all determine whether an accessory will work for you in practice.

Common pitfalls when choosing car accessories

1. Focusing only on maximum power

A higher figure may look appealing, but it doesn’t automatically mean your car will charge faster. For example, to use a 22 kW charge point, your car needs an onboard 22 kW AC charger. You’ll also need a suitable 400 V three-phase connection. If your car has a lower charging capacity or your home doesn’t have the right installation, the available power will be limited.

The same applies to a USB-C fast charger. A 160 W charger won’t automatically deliver 160 W to every connected device. The device, cable and port you use all affect the actual charging performance.

2. Assuming all connections are universal

Not every electric car uses the same charging standard. In the Netherlands and across the rest of Europe, Type 2 according to IEC 62196-2 is commonly used for AC charging, but always check the connection on your car or plug-in hybrid. For a portable EV charger, the mains plug, maximum current and condition of the socket are important too.

The same checks apply to tools. An impact wrench with sockets included is only ready to use if the socket sizes match the wheel nuts or other fixings you want to loosen.

3. Mistaking safety features for worry-free use

Protection against overheating, overloading or earth leakage is useful, but it doesn’t replace correct installation or inspection. A charge point must be connected by a qualified electrician in line with local regulations. Damaged cables, loose plugs and moisture around electrical connections remain risks, even when a product lists several protective features.

Three specifications to check beforehand

Charging power, current and mains connection

These figures matter when choosing a fixed charging solution:

  • 11 kW typically uses a maximum of 16 A on a 400 V three-phase connection.
  • 22 kW typically uses a maximum of 32 A on a 400 V three-phase connection.
  • A portable 3.5 kW charger runs on 230 V and, on the model mentioned, can be set to 8, 10, 13 or 16 A.

A lower current setting can be useful if you’re not sure how much load the socket or circuit can handle. Don’t use unapproved adaptors or extension leads with a portable EV charger.

Connection, reach and controls

A 5-metre cable gives you more flexibility with a wallbox, but check that it will reach both the parking space and your car’s charging port. RFID controls can be useful if you want to start charging without a smartphone. App controls are mainly useful for scheduling and checking status, but require a suitable network connection.

Battery capacity and output power

When choosing a car jump starter, don’t look only at its stated peak current. Check which types of vehicle the product information says it’s suitable for, which cables are included and how you recharge the unit. For cordless tools, battery voltage, capacity in Ah, torque settings and included accessories are useful points of comparison.

A GaN fast charger is particularly useful if you want to charge several devices in a compact form. For example, a Baseus GaN5 Pro model has two USB-C ports and one USB port. The 65W version distributes power across multiple connected devices according to the stated port allocation. A 160W model comes with a USB-C-to-USB-C cable that, according to the product information, supports up to 240W; actual charging capacity still depends on the connected device.

Frequently asked questions about car accessories

Which charge point do I need at home?

That depends on your car, its onboard charger and your electrical connection. An 11 kW charge point requires a suitable 400 V three-phase connection with sufficient capacity. A 22 kW charge point has higher requirements and will only offer an advantage if your car supports this power.

Is it safe to use a portable EV charger with a standard socket?

It can be, provided you stay within the product specifications and the limits of your electrical installation. Check the earthing, maximum current and condition of the socket. Don’t use damaged cables, unapproved adaptors or extension leads. If in doubt, ask a qualified electrician to check the circuit.

How long does a jump starter or car battery charger last?

Its lifespan depends on storage temperature, how often it’s charged, how it’s used and how well it’s maintained. Store your jump starter in a dry place, charge it according to the instructions and check the cables regularly. A car battery charger or jump starter won’t fix a faulty battery; have the battery checked if starting problems keep coming back.
