Vida IT V506 Slim Power Bank for Heated Vest Jacket Gilet Scarf 2.1A 5V USB Battery Pack Fast Charge Portable Travel Charger for Mobile Phone Tablet PC Flight Watch USB-C with 3-Ports Output (Black)

This is the new version which is slimmer and better than the old version.

Great thing compact battery/charger value for money, easy to use and charging speed quick

Good battery charger for a phone maybe but as an aid to keeping an electric jacket warm, no I was only able to achieve 2 hours on lowest setting of the jacket as compared to another battery I own where I got 12 hours on low setting. The reason for this is that for any battery to be successful to keep a jacket warm, it has to be at least 7.4 output and 10,000ma - Im afraid this battery is only 5,000 and a 5 volt output, yes 5 volts is good but you need a high capacity battery to do the job - My disappointment comes from the fact that I purchased a heated jacket for my ex-partner and she needed a battery for it and so I bought her this one - its good for charging a phone

Fast delivery. It is early days but so far so good. It came partly charged and it took a while to get it fully charged. Since then the charging time has been excellent. It is a slim unit that is ideal for the heated back belt that I have. Bought as a spare but is now in regular use interchanging with the original battery supplied with the belt. It performs equally well as the original battery and so far I am very pleased with it.

lightweight

Nice item bought as a package

Charge only works for about 3 hours maximum. I work in a garage and right now its freezing. Charge the battery every time it goes flat. Being fair i start at 6 in the morning and lasts till around 9. It does make a difference to me. without doubt. tried all the different heats but 3 hours max if you keep it on constant.

Slim,lightweight easy to carry around
