Mayorall, i need ur 12000mah rated power bank...I stay in ile-ife osun state, oau precisely...am not on whatsapp....

Just got Mayor Source v1 pb with digital display. I'm still testing it with bb curve 7 & Leagoo Elite 5. I will post my objective review soon. If you are also using v1 pb ,share ur opinion about d pb here.

See d pictures. D v1 pb was sent in T1 box. Followed-come USB cable is faulty

Result I got after fully charged the pb to 100% for 2nd time: it took 4:30hrs to charge my android phone with 4000mah battery capacity from 20% to 62% while the power bk depleted from 100% to 0% . I used port 1A and also put the phone in aeroplane mode to speed up the charging rate. I v started charging the pb for 3rd time

My observation after fully charged the V1 pb for 3rd time: As usual I put my android phone with 4000mah battery in aeroplane mode to enhance the charging speed. My phone gained 19% power boost from 48% to 67% over 2hrs 30minutes with 2A port while the power bank depleted from 100% to 50% .

My experience using Mayorall latest V1 power bank to charge my Blackberry 9320 Curve 7 with 1450mah battery. As usual I put the phone in aeroplane mode to hasten the charging speed. My phone battery gained 45% from 41% to 86% over 1hr while the power bank dropped from 100% to 75% . Probably the power bank can only charge d BB Curve 7 twice and d power bank will go off (drops to 0% from 100%). I used port 1A of d pb to charge d BB since port 2A failed to charge it continuously.

See the screen shot

It means the power bank is not full capacity. A full capacity powerbank of 10400mah should charge a 7000mah battery full from 0 to 100% using a good charging cable. That is full charging the 4000mah and 75% of the same 4000mah before running out of power.

It should charge the BB curve (average 1400-1600mah battery) about 4 to 5 times before depleting depending on the battery capacity of the BB

4th review of V1 power bank :I used Mayorall 10400mah V1 power bank to charge my BB curve 7 for 2nd time with 1450mah battery (put in aeroplane mode + used port 1A, 2A port not functioning ) . My BB gained 69% power from 14% to 83% over 1hr44min while the power bank power store dropped from 100% to 50%.
Conclusion: The actual capacity of V1 power bank is about 2000mah to 2300mah (21% conversion rate ), not the acclaimed '10400mah'.

I got about 62.5% capacity from OnePlus 10000mah

I got about 62.5% capacity from OnePlus 10000mah

Xiaomi 10400mah gives up to 70% because I can charge the Cubetalk 9x from 0% to 70%.

Xiaomi 16000mah gives even more than that. Its about 80% cos i can charge a Cubetalk 9x fully from 0% to 100% and can still charge an oukitel u7 pro (2500mah) phone from 0% to 100%

Advice to the thread owner is to tell the manufacturer to change the battery cell used in it. There are a couple of good ones.

I just got another device (Xiaomi Usb lamp) to try out V1 pb . See d picture. Let's see how long d pb will power d Usb lamp b4 goes off.

Got 5 hrs of light using V1 pb to power a Xiaomi USB lamp. V1 dropped from 100% to 9% within d 5hrs of usage

Mayorall, I don't know what is wrong with my T1 power bank... It shows charging when I charge it with my charger, but when I unplug it, I discover that it' didn't charge at all.
I've tried charging it with different chargers and it's still doing the same thing.
Pls what should I do?

I recently encounter d same issue wt my pb and I will advice you to change your charger if necessary and just forget the pb to charge for as longer as it will pick up.




mine got fully charged on the fifth day when I encountered such a problem with it which is very unusual but at least it is back running and still serving me well.

Pls how much is your power bank?
How much to ship it to Yola, Adamawa State?
Through which method do you ship?

wats the difference btw the type one of mayor source power bank with charging indicator and type teo without lcd indicator?
