Zinq Technologies 20000mAh Li-Polymer Power Bank with 18W PD and QC 3.0 Quick Charge Z20KP (White)

It's been three years now I have been using it, it still has no issue with battery backup, charging speed or any other. The charging time for my phone has remained same. I got the product at a very discounted rate so I got a fast charging power bank with 20000 mAh at very cheap and affordable rate. It is still bright as if it's new. Just loved the product man

Nicely working till date

I've purchased two of these Zinq 20k powerbanks from Amazon--the cheaper 12W charger and the more expensive (the current item) 18W PD fast charger, back in Apr.The 18W product failed in early August in about 3.5 months. It has been a struggle to get this product returned and replaced. Amazon will not support it or ferry it back to Zinq, which would have been great. I would not mind paying for it to be sent back at my expense but no cigar.Zinq is not sufficiently responsive when contacted by WhatsApp or email. Don't even bother. They just ask you to get in touch with their support center. I live in Bangalore and contacted their service center. I finally got in touch with them. They say that I must personally drop it off and pick it up in a few weeks time. It is going to cost me about 250 rupees to get to them each way, apart from me losing half a productive day. So, it is going to cost me 500 bucks to replace a product which cost me about less than a thousand in the first place. This is unacceptable!Why can't Zinq just allow customers who require warranty service to just courier it to either their service center or back to Zinq themselves. It would save us a lot of time, effort as well as money even if it would cost us to send it one way.I am without a powerbank for a month and I've spent an inordinate amount of time talking to at least 3 players with no succor in sight: Amazon, Zinq and the Zinq service center.Sometimes products fail and out of 2, one failed. I am perfectly willing to give them a pass on quality control, but the warranty and replacement process makes me not want to deal with Zinq ever again.I will also ding Amazon a little bit here. Their policies are legendary in terms of customer service and I've been an exceedingly happy Prime Customer, but they should vet and pressure their merchant to better support purchasing customers.

One extra star for value for money.I needed a power bank with two way charging, PD and QC support to use it with phone also occasionally with my Router.This one doesn't have 2 way charging unlike claimed in Feature and Details.I have Mi that support 2 way charging but bought this due to support for PD, type-c port.Both ports support QC as tested but not sure how much wattage it is able to provide. Also PD seems to be working fine, able to get QC charging using it.For charging power bank also both usb and type-c has QC and the voltage shows 9V but the ampere remains around 6-700 mA so it is actually drawing less than 10W of power.My old Mi 20000 power bank charges at 12V and around 1.5A.Tried to return(No 2-way support is deal breaker for me) since i dont think this is specific to my power bank but since we need to go for replacement on first instance, i applied for a replacement. Shall check and put return for a refund.Returned iball power bank also few days back for the same reason.So at this moment we dont have a Power bank in Indian market that supports both PD and 2-way charging.

Okay i brought it before a day.Unboxing it,package is nice.Charged it to its full and started testing the capacity of the powerbank. I charged a realme2 twice,4k mah battery and an asus zenfone max pro m1 twice and half,5k mah battery(all from 20%).It works good but if you want fast charging better use your original datacable.Charging takes 7 -8 hours in 2A charger also its a misconception that the power bank and the mobile connected are charging simultaneously,its not.So first charge the powerbank then ur mobile from the powerbank.Thats the only cons i was able to find.I hope its durable.This product is something most powerbanks fail to acknowledge.Its lovely and its backup is terrific.buy this one.And i will keep you updated about this product n stuffs.Till then goodbye.Its october now and the powerbank still works powerful. I charge my phone 5k mah battery thrice. Its amazing. I am hoping to buy one for my uncle too..

QC 3.0 this is what it is supposed to,And it does that pretty darn well, when connected to a single device. You connect two, and it charges if not so quick, but pretty fast than normal.I have two of these, one I keep in my bag, another in my car glove box, for emergency uses.Yes, it serves the purpose, and quite brilliantly.One was purchased approx 800, the second bought in sale at around 600

This product is very nice this battery backup and power back this nice good thing so much Amazon

I was apprehensive about getting this product since the brand name wasn't familiar but I took a risk and it paid off. I bought it since I was going for a multiple week's trekking. So I needed a good power bank to change my gopro for many days. Even at high altitudes in the cold this power bank didn't drain too fast. So I am pretty happy about my purchase.Check out the weight. It weight a bit more than you expect. But if it is giving good battery life, its good. The usb connection was a bit tight . So I had to apply some pressure to plug in and out my usb cable.The indicator lights can be a bit of a problem as it sometimes can malfunction. But I still think as a powerbank this product does it job well. These minor hiccups can be omitted.
