Review: A valuable piece of equipment - I’ve had to use this twice, and both times it did not disappoint.

I charged it for the first time last week since I purchased it months ago. I have been using it on the same charge it came with! Definitely a must have in any vehicle! ### ⭐⭐⭐⭐⭐ A valuable piece of equipment *by C***R on March 20, 2024* I’ve had to use this twice, and both times it did not disappoint. I used it to jump start my car battery and it started right up- in fact when the Road service came to replace my battery an hour later, it still started up just fine. I used it to power my wife’s cellphone when we were using the Maps on it to find a location. It did a great job using the seperate port for it. ### ⭐⭐⭐⭐⭐ Works better than my LARGE jump box *by B***R on May 13, 2023* I didn't think it would work. I was so excited that it worked better than my large jump box that I paid almost 300 for. The most impressive thing was..I had a dead cell and my battery would not charge. I had to jump it every time I needed to start my car. I wasn't able to get a new battery for two weeks. This little guy NEVER let me down. I jumped my car at least 60 times and I only charged it once. It's amazing! ## Frequently Bought Together - ASPERX AX4500 Jump Starter, 4500A Peak Car Jump Starter for Up to All Gas and 10.0L Diesel Engines, 12V Battery Starter with 4 Inch LCD Display, Lithium Battery Booster with Built-in LED Light - Energizer Jumper Cables for Car Battery, Heavy Duty Automotive Booster Cables for Jump Starting Dead or Weak Batteries with Carrying Bag Included (16-Feet (6-Gauge) --- ## 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/512268478-asperx-ax2500-jump-starter-21000mah-2500a-battery-jump-starter-10l](https://www.desertcart.jp/products/512268478-asperx-ax2500-jump-starter-21000mah-2500a-battery-jump-starter-10l) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-06*
