Mandu Deco Rechargeable Kpop Lightstick Battery for K-pop Concerts, Protective Cap with Keychain, Lasts 4 to 6 Hours, White

I have always hated using then disposing of 3 AAA batteries every time I attend a concert or event and use a light stick. This rechargeable pack fits my Ateez lightiny, BTS Army bomb, and Stray Kids Nachimbong perfectly and works in all 3 with ease. It is rechargeable with a USB-C cable just like I use to charge my phone and battery packs, and I love that it has a screw-on cover to protect the power port when not in use that also has a keychain attachment so I can attach it to my concert bag and find quickly. I love having a more sustainable option to joi9on the fun at my kpop events!

Works perfectly for V4 BTS lightstick. Came mostly charged and a little sheet of cute stickers. Excited to put it to the test in a few weeks.

Works exactly as expected. It’s straightforward, good quality, and gets the job done, excellent for concerts, so you don’t have to be purchasing batteries for your lighsticks.

Compatible with Nachimbong (Stray Kids) and Lightiny (Ateez). This worked out great but I did need to switch to regular batteries during a concert. To be fair that concert was outdoors on a really hot day, which can make rechargeable batteries drain quicker. This is definitely a more user friendly than carrying multiple batteries and switching them into their slots, but I recommend carrying the original battery holder with batteries just in case.

I charged the battery fully then tested it. After 5 hours in the flashing mode, it was still going. I also tested just in the constantly lighted mode and it lasted 5+ hours. That's enough to get me through a concert (BTS ver 4 light stick)

3rd request for a review. Here is my 3rd review. Item came fast, fits great and works. Thank you.

Order is on 5/7/26 just received on 5/9/26 us this on my bts version 4 light stick and it works perfectly I will highly recommend this product.

I just found out about this rechargeable battery after going to the Stray Kids concert. I wish I knew about it before, so I wouldn't need to worry about changing and buying extra batteries. I really like how it works exactly like the usual battery insert. It comes with a short type-c cord, and a charm strap to bring on the go. I do recommend it.

Suuuper bien, tenía miedo de que se me apagara a medio concierto pero nada que ver, la pila fue increíble y funcionó perfectamente en todo momento y hasta me sobró pila ya un día después sigue prendiendo, fui a ver a bts y desde dos horas antes del concierto y tooodo el concierto estuvo prendida y aún tiene batería

Me encantó! Tardó menos de 5 días en llegar y funciona perfecto. Confirmo que funciona para la Army Bomb SE y la Ver. 4 que acaba de salir. Actualizaré de duración después del concierto pero si aguanta entre 3-4 horas de pila. ^^

Jala super bien lo recomiendo 10/10

Si funciona, mi army boom se oxidó de la parte de las pilas y la pila funcionó para que volviera a encender :)

Funciona perfectamente bien. Cuando me llegó la probé con mi LS de EXO y duro más de 4 hrs. Recientemente la use para el concierto de Baekhyun, fue un concierto de poco más de 2 hrs y funcionó perfectamente bien. La batería se carga rápido y viene en un estuche fácil de cargar y con su cable.
