Vida IT 5000mAh Mini Power Bank Small Portable Charger for Heated Vest Jacket Battery Pack for iPhone Samsung Cell Phone with Dual USB Output, Lightweight Rechargeable Power Pack 5V 2.1A for Travel

Works great and compact.

For the size the battery life was great.

These little boxes work great for my heated apparel. They are so light weight! However, I do work outside on a farm so I have to switch them out as they die quickly having the apparel on "high" during negative temps. Highly recommend though.

You can only get one charge off of them not worth the money

I bought this to go specifically with an Ororo jacket and the connector is not compatible. I'm keeping the charger as it is lightweight and small, but just a tad disapppointed.

It does work well but it's hard to know what size you need. There is a button on the side that illuminates 1 to 4 small lights to tell you its remaining charge.

Fits well on my robot cats!

I got these because they stated they'd work with the ORORO heated vest. I really wanted these to work. Pros: - they are small/light compared to the same power ORORO battery pack - 2 pack, same power as ORORO battery pack in smaller package Cons: - they require an adapter (ORORO jack to usb-c) - they don't meet the power/compatibility requirements for most adapters - they make using the vest "fiddly" Using the original ororo vest battery, you just press the power button, and it turns on. Great. I thought these would be the same experience. So purchased a usbc adapter and these batteries. BUT 1. These batteries require you to press the power button on the battery before turning on the vest. That took me 30mins to figure out the first time I tried to use this battery. 2. After you turn the battery on, you have to fiddle with the adapter (plug in, remove, re-plug in) and mess with the vest power button. - usually, the first time you press the vest power, the light turns on, then immediately turns off... - after you mess w/ the battery, adapter and vest power button, it works... BUT 3. The heating power seems "less" than the ORORO battery. So these are going back. I really wanted them to work. The size/weight is great. They're just too much of a hassle.

The packet and batteries are good - 100%. The delivery was terrible, left on a front porch almost in the rain and no attempt to hide from walkers by our property.

Buena capacidad de carga y eficiente para el uso que se le dió

Great item, was purchased for a heated gillet, previously bought a different model/make and it never worked. Purchsed this little gem and it works a treat. So lightweight and compact. Charges very quickly and last for hours/days. Charges my samsung phone great. If you are thinking of purchasing for travel/hiking/work (i work on a building site with no power) then i would highly recommend this. Even comes with a 12 month guarantee.

La compré para mi chaleco climatizado y no me sirvió. Tal vez para celulares esté bien.
