Finally, the Charge has a built in rechargeable battery that will last for months on a single charge. *PLEASE NOTE - if the timer is not going to be used for an extended period of time, the battery must be charged at least once every six months.* For use with: HIIT, CrossFit, Cardio, Weightlifting, Strength Training, Kettlebells, Running, Learn-to-Run, Run-Walk-Run, MMA, Tabata, Boxing, Martial Arts and more. Review: 画面に大きなヒビが入っていました - 最初から画面に大きなヒビが入っていました。プラスチックのカバーにはそれほどダメージは見られないため、輸送中の事故ではなく、梱包前にすでにヒビが入っていたのではと推測されます。検品など全く無いのでしょうか？この硬い画面にこのレベルのヒビが入るって相当の事だと思うのですが、気づかないはずがないですよね？8,000円以上する品でこの品質は非常に残念です。 Review: Produit top ! - Pour mon usage,timer pour la boxe et le cross training c'est parfait, on peut faire des intervalles à gogo. le fait de ne pas avoir de pile à changer c'est cool, mais penser à surveiller la batterie. la fonction Bip à deux volume différent, en plus de la fonction vibreur. la fonction vibreur permet de ne pas déranger son voisin à la salle de sport. il n'y pas 50 fonctions, un outil pratique pour coacher lorsqu'on ne peut pas utiliser sa montre ou son téléphone et qu'on a besoin d'un signal sonore bien audible comme à la boxe. ## Features - Compact interval timer times one or two intervals between two seconds and 99 minutes.

You can choose if you want your timer to beep high, beep low, vibrate, or a combination of beep and vibrate on all four of our models, Classic, Plus, Charge, and MiniMAX. **Q: Can you feel this vibrate when using with the wrist watch adapter? I’m worried about not hearing the beeps if listening to music while running.** A: Yes. That was exactly why it was invented. We wanted people to be able to feel the vibrate on the wristbone if they were using the timer while running and listening to music. **Q: How long will one charge last?** A: Well it depends on how often a timer is being used of course. Generally the timer will last 3 to 6 months on a single charge. **Q: Does Gymboss have one that can be used in a pool** A: Not at this time no. The timers cannot be submerged in water. ## Customer Reviews ### ⭐ 画面に大きなヒビが入っていました *by ち***や on 18 January 2026* 最初から画面に大きなヒビが入っていました。プラスチックのカバーにはそれほどダメージは見られないため、輸送中の事故ではなく、梱包前にすでにヒビが入っていたのではと推測されます。検品など全く無いのでしょうか？この硬い画面にこのレベルのヒビが入るって相当の事だと思うのですが、気づかないはずがないですよね？8,000円以上する品でこの品質は非常に残念です。 ### ⭐⭐⭐⭐⭐ Produit top ! *by T***Y on 21 March 2024* Pour mon usage,timer pour la boxe et le cross training c'est parfait, on peut faire des intervalles à gogo. le fait de ne pas avoir de pile à changer c'est cool, mais penser à surveiller la batterie. la fonction Bip à deux volume différent, en plus de la fonction vibreur. la fonction vibreur permet de ne pas déranger son voisin à la salle de sport. il n'y pas 50 fonctions, un outil pratique pour coacher lorsqu'on ne peut pas utiliser sa montre ou son téléphone et qu'on a besoin d'un signal sonore bien audible comme à la boxe. ### ⭐⭐⭐⭐⭐ Interval Timer and Stopwatch *by E***T on 6 March 2026* Good ## Frequently Bought Together - Gymboss Charge Interval Timer and Stopwatch - Gymboss Interval Timer and Stopwatch Watch Strap – Black - Gymboss Interval Timer and Stopwatch - Black/Blue SOFTCOAT --- ## 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.kr/products/372831256-gymboss-black-red-charge-interval-timer-and-stopwatch](https://www.desertcart.kr/products/372831256-gymboss-black-red-charge-interval-timer-and-stopwatch) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-19*
