CTEK RB 3000 Portable Jump Starter - 3000A Battery Peak Current review
Drivers who want a compact, well-made jump starter that doubles as a genuinely useful USB power bank and torch, and are happy to pay a premium for CTEK's build quality and safety protections.

A solidly engineered, compact booster with proper reverse-polarity and spark-proof protection, but CTEK charges a premium versus rivals and — unusually for this category — doesn't publish an engine-litre coverage figure, so you're working from amp numbers alone.

- Reverse-polarity protection and spark-proof technology built in
- Doubles as a genuinely useful USB-A/USB-C power bank (16,000mAh/59.2Wh) with a 3-mode LED torch
- Compact, IP65-rated build with a 2-year warranty
- No published engine-litre (petrol/diesel) coverage figure — CTEK quotes only current (1300A start, 1980A max cranking), making it harder to size against your vehicle than rivals that state '9.0L petrol/7.0L diesel'-style claims
- Noticeably pricier than similarly-rated 3000A boosters (e.g. NOCO Boost GB150, ~£206)
Who shouldn't buy this
you want an on-the-box litre-engine guarantee for a large diesel van or 4x4 — CTEK doesn't publish one, so cross-check the 1980A max cranking figure against your vehicle first, or consider a rival that states a litre rating directly. Also don't leave it in a hot car in direct summer sun, and recharge it every six months or so if it's sitting unused — like any lithium pack, heat and long dormancy both degrade the cells.
