DEWBU Power Bank 12V Battery with Intelligent Led Display Battery Charger for Heated Jacket, Outdoor Electric Heating Coat, iPhone, iPad, Samsung Galaxy, Android, and Other Smart Devices

The 12v output of this power bank is a real boon.Both the 4X1.7mm barrel socket and the USB-C can provide 12 volts - 18w in the case of the barrel socket and an impressive 36w from the USB.I use this to power an astronomical telescope, which it does effortlessly.The "Charge Remaining" LED readout is a big plus.

When fully charged good life time just Wish I could charge my phone from it too

over priced for 5000mah battry

Needed an extra battery fir my jacket and here it is

I bought this for my Milwaukee M12 heated Toughshell jacket and can confirm it works great, BUT you do need a separate 2.1mm male to 5.5mm female adapter (I bought a right angle one on Amazon that works perfectly).That said, highly recommend this battery:* Flat shape is MUCH more comfortable to wear in the jacket, easy to forget it’s even there compared to an M12 battery pack.* Percentage of battery life display is very helpful for deciding when to recharge.* Battery life / heat time is very good.Really the only minor negative I have found over a few months of regular use, is that the battery goes into a sleep / hibernate mode if something is plugged in and not pulling current. You can’t turn on the jacket while it’s plugged in unless you press the battery button first to wake it up. However, that also helps avoid phantom draining of the battery and in practice I’ve found it very easy to hit the button with my left hand through the material of the jacket without taking it off. It only takes a second and I very quickly got used to doing it as soon as I put my jacket on.All in all this has been a great add-on for my jacket and 100% worth it for the comfort factor alone over an M12 battery brick sticking into my kidney. I wish it was a little bit less expensive because I would like to pick up a second one as a backup battery, but it’s a somewhat niche product and I can understand the higher price point over battery packs that don’t offer 12V out (or charge status displays for that matter).

I’m a sound engineer music producer and i git this to be able to power my UAD APOLLO TWIN while i’m traveling since it needs power supply to work but sometimes i don’t have access to a power outlet. Well, this thing powers my apollo for about 3 hours, enough to do a lot if needed.Really small, light, status screen very useful to know how long you still have.

Bought an extra battery pack for the jacket and haven't used it yet, but a good power source for my other devices.

Same product as the original. Works well.
