Review: Everyone needs this in their car! - I live alone on a lake in the middle of nowhere. Came out there day to a dead battery and ordered this guy! The NOCO Boost GB20 has been one of the most useful automotive gadgets I’ve added to my car kit. This little jump starter packs a surprising punch — it easily starts my 12V vehicles with engines up to 4.0L gas without hesitation. What I love most is how compact and portable it is; it fits in a glove box or backpack, so it’s always ready without taking up much space. Setup is super simple: just connect the clamps, and the LED indicator lets you know you’re good to go. The UltraSafe technology gives extra peace of mind because it’s spark‑proof and reverse‑polarity protected, so even if you clip the clamps wrong (we’ve all been there), it won’t hurt the battery or device. Beyond jump starting, the built‑in USB port doubles as a power bank for phones and gadgets — perfect for emergency charging on the go. Battery life stays strong between uses, and the GB20 recharges quickly so it’s ready when you need it. If you want a dependable, easy‑to‑use jump starter that’s more powerful and safer than a traditional roadside pack, this one is absolutely worth it! Absolutely a great value and gets your car going quickly!

## Questions & Answers

**Q: what is the life of the  lithium battery??**
A: The life depends on a lot of factors just like any other lithium battery pack. How many jumps are used, when and how often it is charged and discharged, storage temperature, etc.As of now I've jumped several vehicles with it (4.0L and larger sized engines), draining the battery down 25%. The booster has sat for two weeks and it still reads the same, so it hasn't lost much, if any, power from just sitting.

**Q: Can i recharge the device with 220v power supply?**
A: Only through a computer.  There is a USB, but no 220 or 110 cord/adapter.

**Q: How long is the cord for the Charger power outlet  adapter cable ?**
A: Not sure how long it is, but is very short. Although you don’t need anything longer unless the battery of you car is placed in an awkward position with the terminal facing sideways or hidden. It work fine for my Acura MDX and Ford F-150

**Q: Tengo un honda civic 2006 de gasolina , funciona bien para ese ?**
A: Te va a funcionar perfectamente

### ⭐⭐⭐⭐⭐ Device works exactly as described
*by A***Y on January 2, 2026*

Bought this thing a month ago, charged it fully and kept it in the trunk. Woke up today to a dead battery in single digits temperatures. Rushing to go to work with no time to waste, this little beast started my truck in a single start. Gave it 5 stars for keeping 100% charge through a month of freezing temps, and for working in a start despite the battery being fully dead. It still showed fully charged even after that use.
