12V Power Bank, Rechargeable 12V 3000mAh DC Output Lithium ion Battery Pack with Charger for LED Strip/Light/Panel/Amplifier and CCTV Camera, Compatible with Spectra Pump/Telescope

Works amazing for my pink spectra pump! Fits perfectly in the cup holder. I can get around 10-15 pump sessions on one charge. Comes with the connector and everything.

Perfect for my spectra pump to make it portable-also fits perfectly in the little cup part. It gets me through a whole day of pumping and charges quickly when it does need charged- and was cheaper than the upgrade for the portable pump when I got my pump through insurance so that’s a win!

I made the AMT Enterprise D model and lighted it straight wire using 12 volt led strips. I only used two independent 12 volt led’s with resistors to light the busard collectors. (The red glowing things) All static no flashers. I initially used a nine volt battery as a power supply but was disappointed with the brightness. This battery pack did the trick and increased the brightness by approximately 50%. I had to cut off one of the male plugs, pig tail it and solder it to the positive/negative wires I used to light the model. None of the reviews I read mentioned using this as a power source for modeling so I thought I would. It will work great for such projects. The photo was taken during daytime hours and the lights are still very visible.

Great purchase and works well with the strip lights that I purchased! True to description and easy charging.

This power supply is great for upping the 5V voltage to 12V on my Arduino Motor Shield V2 by externally powering it via its positive and negative terminals. I can now run 12V motors without an issue... Almost. This thing only has one input/output barrel jack, where this would generally be an okay option for passthrough charging, in my case it doesn't work at all. I am splitting this power and stepping it down to 5V on one side going to a Jetson Nano, and the 12V that is split and not stepped down goes directly into the Arduino motor shield V2 board. The reason I am not just putting it directly into my Arduino Mega is because I am using the USB for serial communication, which means it will send power over that regardless and if I try to add 12 more volts it will damage my components most likely. This is where the input/output single barrel jack issue comes into play. I would be able to charge this battery with it off and not send power to the rest of my circuitry if it had a separate output. But with the splitter it still sends power down the line to my motor shield V2 and the jetson nano from the wall. However the wall power is not enough for the motor shield v2 to run the motors when split between itself and the battery in its off state. If it was I could look passed this issue. All in all its a little disappointing that I will have to make the battery removeable for charging (most likely using a 3d printed case to slide it into on the bot), but it's not the end of the world, as when I am not trying to pass through charge and I am just using battery power for the bot directly from the bank everything works as intended. If you wanted this battery to be more multi-faceted for developers and makers like me, possibly consider removing the power button all together and implementing a switch in the DC chord maybe, and then give it one input DC port and one output DC port. A 12V 3A battery with 2 DC ports in and out at an affordable price would be a product I'd buy for almost ever build lol. All in all its a solid battery, it just isn't exactly what I wanted originally. Had to get my hands on it to see first though!

Using this for my Spectra breast pump. Makes me mobile and works so far!!!

Charged up fast ,powered my item

Works great use it for my breast pump and it’s lasted days of pumping so far!

Great battery pack for my FX-4CR

Works perfect for giving a non portable pump a new free lease on life. Best of both worlds, strong power and portability. We haven’t had any issues with the pack not lasting, but we make sure to plug it in between uses

Very nice compact 12-volt battery pack. I use this for my wifi camera for my truck and trailer. Lasts about 30-40 hours per charge.

GOOD QUALITY OF PRODUCT

Liked the built in charge indicator lights. Good to have a supplied charging splitter cable. Battery has a decent capacity for its size.
