12V Battery Pack 5200mAh Rechargeable Battery for LED Strip/Router

Still holding a charge years later.

Yes! I bought it to power a back massager that needed to be plugged into the wall. now it doesn't!!!

works great

charged using a 12.4V 2A charger... battery is used with a Penntek TR-35 CW transceiver, and lasts several weeks of outings while QRP /P... a hidden feature, not documented on this product page, is LED readout of battery state by pressing a circular button under the PVC wrap on the output and charging end of the ganged batteries - convenient if your device does not have voltage readout i generally avoid lithium ion batterie in favor of lifepo4, but this battery's features, size, weight, and capacity is just right for my quick go kits

I had purchased this battery pack for a project that I made. It has two connector wires, one male, one female coming out of the battery pack. The instructions does not show which one is the charging connector and which one is the power connector. So I took a guess and cut the male connection. On that side, I applied the 12.6 volts at 1 amp to charge up the battery. I don't know if it's right or wrong, but I'm monitoring it to see if it'll work. Just as an FYI, I cut the wrap and off to show the internals of the battery pack. Yes, I do know how dangerous lithium ion is and I am monitoring it while charging.

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’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

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