Better dun get those 30000mah powerbank, later will end up charging the powerbank like siao
20000mah powerbank already take around 11+ hours to charge with 2A input, the 30000mah will take around 16+ hours to charge provided it is really 30000mah capacity

If the powerbank is using a 12V type charger, should be OK. If using those normal 5V charger, charge till pengsan

Yoobao quite OK lor, the newer series I mean. Aluminium body with 2A output and 2A input, I dont think can go wrong?

Actually it is about there.
Normally those China powerbanks (including Yoobao) have efficiency of 65% only due to loss of energy in heat, resistance in the cable, etc, etc.

5200mAh X 0.65 = 3380mAh of usable power

3380 / 2300 = 1.47 times

So yeah it can only charge your phone around 1.5 times

Xiaomi not mistaken claiming efficiency of 90%, but I not sure how true is that as I didnt use Xiaomi powerbank before

You could give Anker a try

Ntg much to discuss about powerbanks compared to casings and screen protectors

If you want a powerbank that can charge iPhone at least 3 times, u need to at least aim for 8000mAh and above powerbanks

Erm less than 9 hours to recharge 20000mah powerbank? Using the standard microUSB cable to charge the powerbank? Bcos fastest to recharge a 20000mah powerbank (assuming 5V 2A input) also need around 12 hours to recharge the powerbank..

Hmm this charger output at most the max per USB output will be 2A. I believe the 4A will be the total output for all four usb ports if all 4 USB ports are used

Seems like hit and miss for xiaomi powerbank. Some say very good, some say not good at all. Though the pricing is very attractive

Can consider Aukey powerbanks also, got quick charge 2.0 and also fairly cheap

Lol I got like 5 powerbanks

I mainly use 3 powerbanks
1 for phone, 1 for tablet and 1 campak in my work bag for backup
The other 2 collecting dust in drawer

Because last time only Yoobao dominate the market for Powerbank
Now got so many other good choices
Yoobao can say is like Nokia

Aukey quite good powerbank

Pirated powerbank izzit
10000mAh should be able to charge at least 2 times

Can consider AUKEY powerbanks

Considered cheap already as it is equipped with Qualcomm Quick Charge capabilities.
The cheaper powerbanks do not have Qualcomm Quick Charge.

Pineng powerbanks are okay actually, just make sure you buy the original Pineng and not the pirated

20000mah in a small form factor? Most probably it is not 20000mah

Looking at around rm199 for the 30000 powerbank

Can consider ANKER Powercore+ 20100 USB-C, premium built & nice form factor for a 20000mAh powerbank, though pricey
