I use the product for my Spark amp. It does what it needs to do and lasts for days. For reference, i use the amp for about 30-45 minutes each day. I don't need to recharge for about a week. Even when I do need to recharge, I only need to recharge it for a short amount of time before it's back at full charge.

First Pack Bad - Replacement pack has very little capacityI purchased this pack to allow portability of my Positive Grid Spark guitar amplifier. The first pack I received either had defective cell(s) or a defective charge/analyze circuit. All led’s of the 4 step led charge indicator would illuminate when the pack was charging, but only 2 or 3 would illuminate when the charger was disconnected from the pack, even after 5 days of charging. Amazon did send out a replacement pack immediately. The new pack displayed a 75% charge upon arrival, I was worried, but after a few hours of charge time all 4 led’s illuminated as expected. I haven’t used the Spark for more than 2 or 3 hours at a time but so far the battery pack has worked great and the portability aspect is great. I’ll update the 3 star rating in a few months after more testing and use. I’m always leery of “unusually named” crappy Chinese lithium battery products and their very optimistic rated vs. actual capacity. Lol

By the way, the magnetic phone mounts work great and far better than I expected as an option for mounting the battery.
One year later…Replacement pack does not fully charge and dies after adding only 20% charge to my iPhone 14 Pro Max.
I maybe have 15-20 hours of use with the Spark amp. Really disappointed. I’ll take it apart eventually and replace the cells.
Update….Who cares……This pack, yep #2, is an absolute POS. I’ve made multiple attempts to reach the seller!!!😂😂😂😂
Who am I kidding. Great idea, but super crappy execution. I look forward to a proper, tear down and analysis! Ordinarily wouldn’t take the time but I’m almost irritated enough to add it to the list of projects!

Versatile
Dernièrement, un derecho a frappé ma région et pour la première fois de ma vie, l'électricité a été coupé pendant presque 36h. Heureusement que j'avais cette batterie. Elle a été bien utile. J'ai été en mesure de recharger mon téléphone, ma tablette, un haut-parleur Bluetooth et mes 2 paires d'écouteurs.VersatileStephane

Quand la batterie est complètement déchargée, il faut environ 3h pour la charger avec l'adaptateur fourni.
Selon l'angle, l'indicateur de charge n'indique pas bien. Par exemple sur la photo on voit 3 dels allumées mais il faut regarder bien en face, en réalité seulement 2 sont allumées. Quand toutes les dels sont éteintes, il faut recharger rapidement car il ne reste plus beaucoup de courant. Une chose agaçante, quand les prises USB sont dans le bon sens, l'indicateur de charge se retrouve en dessus (voir photo). Pas très pratique.
La charge rapide est parfaite. Mon téléphone Samsung A50 passe de 20% à 90% en environ 1h08.
Mon ordi portable se recharge très bien aussi grâce aux connecteurs fournis.
Bizarrement, il n'est pas nécessaire d'appuyer sur l'interrupteur pour avoir du courant sur la prise DC2, le courant est toujours présent. Mais il faut appuyer sur l'interrupteur pour avoir du courant sur les prises USB-C et USB-A.
J'aurais préféré que cette batterie se recharge aussi par USB-C (pour la recharger dans une voiture par exemple) et qu'elle utilise un panneau LCD pour indiquer la charge en pourcentage.
Il y a peu de batteries portables qui offre le 19,5 Volt, c'est pourquoi, j'ai choisi celle-ci. Donc un bon achat, reste à voir la fiabilité à long terme.

Half Capacity in 1 Month
I don't like to write bad reviews, but I'm pretty disappointed in this product. After a month of having it and not using it much, the battery pack will no longer charge beyond the halfway point, so it has half the capacity and lasts for half as long as advertised.Half Capacity in 1 MonthSam Gamper

The return window has already closed so I'm really hoping someone from the company will reach out to provide a replacement, as this was a really unsatisfactory experience.
