iVOOMi Titan 15000mAh Li-Polymer Power Bank with Smart LED Panel (Carbon Black)

Works just fine, Been using this for a week now. It works pretty well. Very attractive and eye catching. Delivery was right on time. When fully charged it can recharge a phone of 3500 MAH atleast 3-4 times. Worth the money. The colour changing is so dope.

good one by looks and quality... and its charge verry quick...

If you have iPhone and want to use this powerbank then it’s worst everIt cause damage to my two iPhone cablesAnd charging or iPhone suddenly jumps many percent like from 10 to 20% in 3 minutes but it’s not realAfter few minutes battery start reduce form 20 to 19 18 etc.For the android it was working ok when I testedBut for the Apple device it’s really worst ever power bank.Never ever use this and even if you like then can try yourself.I am also using mi power bank that never create this issue and works always fine.

Only problem of this product is power on/off button, first unit which i get power button embedded inside than i replace it, fast replacment done by amazon thank you amazon. With new unit still i m feeling power on/off button should be more solid. May be i m worried bcoz if my first unit. But i want ivoomi should improve its build quality. No idication for full charge.

The pics are from the 10K one I opened up thinking the battery had a bulge, this one also have a bulge but the case itself is made that way so its thicker in the middle than the ends.. I expect both models to be identical except one has the extra battery for the extra storage.This came in the normal box and contained a USB-C to USB-A cable to charge the device.. Or I can charge a phone with a USB-C device.. But for other types of phones you need to get a different cable. I am not sure if the USB-C port on the power bank can charge a device since I do not have a cable thats compatible although I could have used my USB-C to USB-C cable to test but I did not feel like taking the chance. I always test things on cheap devices to see if they work before I use them with expensive stuff..This one also charges a 3000mah phone in under 2 hours or 80% in like an hour.. The power bank said it was 3/4 full when I got it and took another 2 hours at 2A to fully charge it and after charging the phone it is said it was over 3/4 full so I can charge a phone 3 times and some, while with the 10K charger I can charge a phone twice and some.. Dont let the numbers fool you.. Not many will come anywhere the numbers published.. Even this one the 10K or 15K numbers are for the 15K battery at 3.7Volts.. At 5V that comes down to almost 10K mah.. Another thing is, the battery capacity depends on the voltage.. So if they use 4.2V then it wont charge the battery to 100% but to only 90%.. most power banks only goes to 90% so the power bank lasts longer as charging to a lesser level means more charge cycles.. At 4.3V it gets to over 100% rated capacity but the number of charge cycles drops by 25%.. And I measured this one to 4.2V while others stop at 4.1V or 4.18V etc.. Nothing went above 4.2Volts.. This could also be that the chips used were designed when Lithium batteries were based on 3.6 Volts and not 3.7 Volts.. Its cheaper to make 3.6V batteries than 3.7V batteries.. Yes there are dozens of types of Lithium batteries depending on what you are going to use the battery for and they are all similarly numbered and look the same. So the battery inside your phone although looks similar is not the same as the ones used in this power bank, on 3 phones I checked the Samsung only charges the battery to 4.28V, the Google Nexus to 4.34V and the Blu phones it charges to 4.38Volts. As you can imagine the samsung lasts longer in the number of charge cycles even though it holds the least charge so you need a bigger battery to get the same screen on time.The style uses the same back lighting system used in your phone.. Its really bright when you take it out but not so bright inside.. Also you cant put the case back together like new as its very delicate..

As promised nice product and totally value for moneyMain and highlightee feature is working perfectly fine the color changing led panel which is a key selling point of this product and rather then that the build quality of this product is beautiful and strong another impressive part is it really really support fast charging...In short with in this price range go for it without any single thought...

Product is working quite well. It is 15000 mAh powerbank, but I manage to get two and half round of charging capacity on my Redmi Note 4 (4100 mAh). It seems that power loss (which is normal for all powerbanks) is slightly more for this one. But there are 2 small problems - 1) you have to use your own sense because it takes more time than what mentioned on user manual, 2) it does not have any torchlight led which it should, at least with its relatively high price-tag.

Really nice power bank charges my s8 twice from 10% to 100%..... ita a bit heavy than other power banks but serves the purpose and its better in quality than the previous power banks i had.
