We compared two portable 12V car jump starters: the Tarden 6000A Jump Starter Power Pack and the NOCO Boost GB40.

What we looked at

Extra functions, peak current, and price.

The verdict

If you want the lower price on a jump starter that also doubles as a 150PSI tyre inflator, the Tarden is the value pick, at £48.99. If you would rather pay £43.39 more for NOCO's patented UltraSafe spark-proof technology and a compact, rugged IP65-rated design, the NOCO Boost GB40 is the alternative, at £92.38.
