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)

Using this product to power a heated gilet, slimline to fit easily and comfortably in pocket. Charge lasts really well.Great product and good value for money

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.

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.

Very pleased with how slim this is and how easy it is to use. Seems to hold its power well

Arrived very quickly. This is a lovely slim, lightweight battery, very efficient, the charge has lasted me a few outings.

Brilliant, great service great value, long lasting very pleased

The power supply appears to be well made, very slim and lightweight. It charges up quite quickly although the duration of it’s output might be exaggerated but I am very pleased with it.

Handy decent power bank I bought to go in my partner's heated gilet. Charges easily and quickly and lasts for sufficient time needed when my partner wears her gilet. Good product.
