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 ## Frequently Bought Together - NOCO Boost GB20: 500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack, Portable Jump Box, Power Bank & Jumper Cables - for 4.0L Gas Engines - NOCO GBC013 Boost Sport and Plus EVA Protection Case for GB20 and GB40 UltraSafe Lithium Jump Starters - NOCO GBC007 18.5-Inch Boost X-Connect Adapter Extension Cable for GB20, GB40, GB50 and GBX45 UltraSafe Lithium Jump Starters --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/20347332-boost-gb20-500a-ultrasafe-jump-starter-12v-lithium-battery-booster](https://www.desertcart.jp/products/20347332-boost-gb20-500a-ultrasafe-jump-starter-12v-lithium-battery-booster) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-01*
