  • Talentcell Spark
Has the adapters and connecting cables I need. Works as it should so far. My Spark amp plays fine with it.

  • Battery for my Positive Grid Amp
Small but loud, 40 watts, I have 4 other amps. I rarely use them. This amp is awesome. Oh, I almost forgot. The battery I bought was a perfect match for the amp. I like to take it outside and jam on back tracks in my backyard.,I have bought many things from Amazon and never been disappointed, thanks again Amazon ... show more

  • Charge Level LEDs Do Not Work/Light Up
I purchased one of these - which I returned because the charge level LEDs do not light up - and purchased a second unit, which has the very same problem. The unit appeared to take a charge as the indicator LED on the wall wart charger turned from red to green, and when I plugged it into my Spark 40, the amp powered up, but with no charge level indicator, I feel that I'm not getting what I paid for and I'm not getting what was implied in the pictures of the product on Amazon. I sure wish it worked properly. ... show more

  • Long battery life
This charger is fantastic. I’ve used it to power a guitar amp for a gig and to charge phones on a 5-day camping trip. Got at least 8 complete charges out of it - I was charging other people’s phones in addition to mine, so I lost count. Love the form factor and the long battery life.

  • does not work with ACER Zenbook Pro 15 OLED.
overall great product I even purchased a second battery because it works well and holds a long charge. the only downfall I have found and reason for 4 out of 5 stars is because it will not charge my Laptop ACER Zenbook Pro 15 OLED. The adaptor that will fit it is actually the HP adaptor however it glitches and doesn't have a secure adaption causing it to not work 98% of the time. Great product except the adaptors. Both batteries and adaptors have the same problem. ... show more

  • Awesome long lasting
This long lasting battery is capable with the spark 40 practice amp making it a tiny portable powerhouse, spark does make a model with a rechargeable battery but this conversion is well worth it if you already own a spark 40. It’s awesome!!!!
