I’ve used this as a fish finder battery in my Garmin. I have the smallest garmin which doesn’t use much power. It lasts several days between charging but I charge after each trip if I can for piece of mind. I’ve used it several times per week, every week for more than a year now. It’s been very dependable and I would recommend this for anyone looking for a cheap power source

Before retiring I designed li-ion battery packs for a variety of applications, including military drones and I wasn't expecting much from this inexpensive battery. My wife wanted a battery for her LED beauty mask and this was a compatible voltage. It told her to expect 7, 30 minute discharges before recharging. Yesterday she completed discharge #9. YAY!

Did not come with instructions to recharge. No cord to recharge. Just the unit

The composition of six 18650 batteries in the SPARKOLE battery pack immediately caught my attention. Through careful calculation, I determined that the battery pack delivers a voltage of 12.6V and a capacity of 5.2Ah. This impressive capacity ensures an ample power supply to keep my devices running while I'm away from traditional power sources.One of the standout features of the SPARKOLE battery pack is its portability. The compact size and lightweight design make it a convenient companion for various activities. Whether I'm camping, hiking, or traveling, the battery pack fits easily into my bag, providing a reliable source of power for my devices.The compatibility with most 12V devices adds to the battery pack's appeal. It seamlessly powers a wide range of devices, from electronics to small appliances, making it a versatile solution for various situations. This compatibility ensures that I can rely on the SPARKOLE battery pack to keep my essential devices charged and operational.However, there are a couple of areas where I've found room for improvement. Firstly, the durability of the outer casing could be enhanced. While the battery pack is lightweight and portable, I noticed that the casing is not as sturdy as I would prefer. This may raise concerns about its ability to withstand the rigors of outdoor use over an extended period.Additionally, the need to purchase a separate charger for the battery pack is somewhat inconvenient. A bundled charger would have added convenience and made the product more user-friendly. Having to source an appropriate charger separately adds an extra step to the setup process, which may deter some users.

I used this to replace a battery in my aiper smart pool vac, with a little rearranging i was able to fit this into the housing as the one that came with the unit was slightly smaller, so far so good, will update if this item fails.

I am using them on my wifi mesh units around the house. Keeps the wifi going even if the power has issues.

I made a portable bluetooth speaker. This battery not only fit perfectly, but works better than anticipated.
