Callmate 50000mAh Ultra High Capacity Power Bank, 15W Fast Charging |Digital Display |3 USB Output Ports and 3 Input |LED Torch| Multi-Layer Protection for iPhone, Smartphones (Black, Lithium Polymer)

I had bought the product, after 2 month of purchase product not working, I had inform to Amazon coutomer care, but they denied to attend my complain. So request to all pl dont buy any electric product from on line purchase, because after sales they are not able to attend coustomer complain against product

Not handy way too heavy and feels like uneasy to carry also when try to charge my mobile it takes too long to charge and power bank gets soon drained where as it has given three usb ports and including two c type ports but design is very bad and heavy.

I like this Power Bank because I never seen a very useful power bank in this price. I am used it last three four months , it charge my XIAOMI MI MAX 2 which have 5000mah battery atleast 9 Times 0 to 100% and it takes mobile charging only 2 hours only. Only one negative point of this Power Bank was it self charging time is too long it takes about 21 hours 5 to 100% , but it's o k because it have a massive 50000mah battery so it takes too long time. It have also a power pass function which allowed us to charge simultaneously power bank and mobile at a time, no need extra power point. Thanks everything to CALLMATE and Amazon to provide this product in very cheep price.

The product is heavy, which is expected due to 50k mah.I expected at least one full charge can sustain for 8 mobile charges, which is not the case.I am not sure if it's a defective piece or the product itself is designed like that.The pic shows just 47% balance, where as it was charged to full and just started to charge an Android phone.Pathetic product which doesn't stand up on its commitment.

Good

Let me talk about advantages first.Good product have been using for 2 weeks, great battery capacity, takes a long time to get fully charged. Almost 20hrs for 100% full charge. It charges my i-phone 11pro max 10 times. U can charge three mobile devices at a time. Good that u can the power bank using multiple ports and you can use all the three input ports at a time to charge it. If you are charging the power bank with single input it takes 20 hrs for full charge, and if you use all three inputs at the same time it will take 10 hrs to get fully charged. Provided with LED lights on top which helps for video calls at nights.Disadvantages : No fast charging Output, the output is only for the normal charging. Usually fast charging fully charges my i-phone 11 pro max in 1hr. However this power bank takes 1 and half hour to fully charge my phone. Apart from not providing the fast charging output this power bank is a real good deal. And its really heavy and bulky. U can crush walnuts using this.

The media could not be loaded. WOW ! What a Power Bank made by India ! Amazing. It's a monster. 50000 mAh. Great back up. Strong light.Weight - 775 gm.3 USB Port.2 strong light.1 micro usb, 1 C-type, 1 lightning.I have posted some pics and video. Check it. You may ask, input is not 5v, 2A. As you know when battery reaches to 80%, current flow decreases, when it reaches to 90%, current flow decrease more, and 95-100% current decrease drastrically.So, need not to be worried. It's not 1kg as mentioned. See my pictures. I have got this 1999/- with a very fast delivery.One more thing to say, it gives fast charge, 5v, 2A max. Many thanks Amazon.
