YFW Power Bank 4000mAh Pocket External Battery Pack Ultra-Slim Power Charger for Samsung and Smart Device (White)

Bought this to take on holiday for that much needed power boost to my phone so I could watch films on the plane etc.Guess I have been spoilt by fast charging but this thing seems to take ages to get even a half decent charge from it.The same goes for actually charging the power bank itself; it takes a good few hours to get it fully charged.Overall not a a bad product but would recommend looking at getting a phone battery case in the first instance for anyone looking to buy this for the sole purpose of using it to charge a phone.

It is not the best quality but it is very slim and light. It can be carried in your pocket and you would not feel it!

Good for a quick charge if your phone runs out of battery. Although does not charge it completely. Get a good hours charge out of it.

It’s ok, thought it would be better! Only charges my phone half way then it dies. Not as good as I thought

good value, quick charge

Great size for small bags. Phone can be charged about 1 and half timed. Very handy. Worth the price. I use it at least 3 times a week. Piece of mind as i use my phone a lot when i am out.

Small enough to keep in handbag but powerful enough to fully charge Samsung S8. Doesnt come with C connection cable for Samsung S8 but cheap enough to buy a cable. Great value for money, highly recommend product.

Excellent power bank. Charges my S3 easily & ehas feel of quality in build and design. On sale at bargain price, so even more value. Would have happily paid full rrp for this.
