A lithium jump starter that lives in a boot for years and earns its price the one morning it is needed.
This entry is written from the 2 sources listed at the bottom of the page. The numbers are our editorial estimates drawn from that material, not measurements, and no statistical sample sits behind them.
On the evidence gathered here, yes. 86% of owners say they would buy it again, and satisfaction is still 8.4 out of 10 two years in. Owners report units working years after purchase.
Sentiment rises the first time it works. Until then it is an object in a boot; afterwards it is the reason you were not stranded.
Capacity fades if stored fully discharged. Forgotten in a boot until the day it is flat. Cold weather performance drops noticeably.
Owners report units working years after purchase. Sentiment across the ownership period stays close to flat, which is rare: it reads 8.2 out of 10 in the first week and 8.4 two years later.
Worth it for: Older cars and occasional-use vehicles; Anyone who parks away from other cars; Cold climates where batteries fail. Think twice if: You would never remember to recharge it; You drive a large diesel needing serious cranking; Breakdown cover already covers you.
