- Choose by CCA (Cold Cranking Amps, the real starting power for a cold start) first, extras second. A jump starter that's too weak won't start your car, no matter how many features it has.
- Small petrol car plus tyre pump: the Boost Air Micro (480 CCA) with a built in compressor, flashlight and power bank.
- Diesel, van or camper with a compressor: the Boost Xtreme 8250 (1920 CCA).
- Just starting, no extras: a plain jump starter like the Boost Mini 3750 (620 CCA) is cheaper and lighter.
A jump starter comes plain, but also as an all rounder with a compressor, power bank and flashlight. On marketplaces you increasingly see these 4 in 1 combos. Handy, but you quickly end up paying for features you never use. Or worse: you buy a combo that's too light for your engine. Below you'll read how to choose the right combination.
What exactly do a compressor, power bank and flashlight do?
The three extra features each solve a different problem. The compressor pumps your tyre back up to pressure, for example after a flat tyre or before a long trip. The power bank charges your phone or laptop on the go. The flashlight helps you in the dark by the roadside, often with a flashing or SOS setting. If everything's in one device, you only need one thing in the boot.
Note: none of these extras make the jump starter stronger. The starting power sits in the CCA value. Read more about that in what CCA is exactly and in peak current or CCA.
CCA first, extras second
The order is simple. First check which CCA your engine needs, then decide which features you want. A small petrol car needs around 480 to 620 CCA. A diesel, SUV or camper needs considerably more, towards 900 CCA and higher. Buy a combo that looks good but delivers too little CCA, and you'll still be stuck. That's exactly the trap with cheap all rounders.
| Model | CCA | Compressor | Power bank | Flashlight | Price |
|---|---|---|---|---|---|
| Boost Basic 3000 | 480 | no | yes | yes | €64,95 |
| Boost Air Micro | 480 | yes | yes | yes | €79,99 |
| Boost Mini 3750 | 620 | no | yes | yes | €94,95 |
| Boost Pro 8250 | 960 | no | yes | yes | €189,95 |
| Boost Xtreme 8250 | 1920 | yes | yes | yes | €399,95 |
Which combination fits you?
Do you drive a small petrol car and want to be able to pump up your tyres on the go? Then the Boost Air Micro makes sense. It delivers 480 CCA, has a compressor up to 10.3 BAR and weighs little. Want pure peace of mind for starting and no compressor? Then go for the Boost Mini 3750 with 620 CCA. For a heavier diesel, van or camper you need more. The Boost Xtreme 8250 combines 1920 CCA with a compressor of about 45 L/min and a power bank up to 65 W, also for your laptop.
- Starting power: 480 CCA, suitable for small petrol cars.
- Compressor: 25 L/min up to 10.3 BAR, with car, motorcycle, bicycle and ball modes.
- Extras: power bank, flashlight and an LED screen with live tyre pressure.
Not sure between plain and complete? Think about how often you'd actually use the compressor. Top up your tyres monthly, and a combo pays for itself. Already have a compressor in the shed? A plain jump starter is cheaper and lighter.
What to watch for with a cheap all rounder?
A combo is only as strong as its weakest part. So watch for three things. First check the real CCA value, not a big peak current figure on the box. Peak current says little about whether your engine will actually start. Then check the compressor: what's the maximum pressure in BAR, and does it stop automatically at the set pressure? A pump without an automatic stop can easily over inflate your tyre. Finally, check the weight and size. An all rounder you leave at home because of its bulk won't help you by the roadside.
Our own combos deliberately choose honest figures. The Boost Air Micro states 480 CCA and a compressor up to 10.3 BAR with an automatic stop per mode. The Boost Xtreme 8250 does the same at a heavier level, with 1920 CCA and a compressor of about 45 L/min. So you know in advance what you're getting, without surprises at your first breakdown.
"Never buy a combo purely for the compressor. Check the CCA for your engine first. If that's right, the extras are a nice bonus."
Frequently asked questions
Does a built in compressor make the jump starter stronger?
No. The starting power sits entirely in the CCA value. A compressor only pumps up your tyres and has nothing to do with starting.
Can I start a diesel with the Boost Air Micro?
For most diesels, 480 CCA isn't enough. Choose the Boost Xtreme 8250 with 1920 CCA instead, which also has a compressor.
Do I need a power bank in my jump starter?
All models can charge your phone. Want to top up your laptop too? Look for a model with USB-C up to 65 W, such as the Boost Xtreme 8250.
Is a plain jump starter better than a combo?
Not better, but cheaper and lighter. Rarely use the compressor? Then a plain jump starter like the Boost Mini 3750 is usually enough.
Does the compressor work independently from starting?
Yes. The compressor and the starting function work independently. So you can pump up your tyre without connecting the battery.
