Definately recommend for travel and such. Can charge multiple devices at the same time and most certainly charge a device multiple times before the bank needs recharging. The powerbank takes several hours to recharge and obviously the higher the Wattage, the faster it will charge.
The only disadvantage is the weight. It is much heavier than other powerbanks so depending on how you travel etc, it may be a bit of an inconvenience.
Nonetheless, it’s a great powerbank to have
However the problems started when I started using this device to power up my Oculus Go VR headset. Powerbank discharges fine up to 55% (according to the screen), and then suddenly stop charging devices completely which means it's only provides 5Ah capacity.
My suggestion is not waste your money and buy Xiaomi instead as its 2 times smaller, support quick charge and cost only $4 more than this one.
Yes, the power bank is a bit bulky, but I like that. Unlike the slimmer power banks, this one has enough space to put a few 18650 battery and keep it going.
Overall, I really like the build quality, looks and features of this power bank and would recommend it.
The amount of recharge we get from one charge is surprising.
Unlike other chargers, it retains its power so that when you do need it, it actually works and fully charges whatever you need!
It has been great for long road trips and all the family devices, not just single recharge use!
Think like almost the size of a relay batton!
I have tried heaps of different chargers by far the best I've used are made by sdoutech which are available on Amazon and literally half the size of these things and can fast charge just about anything !
Top reviews from other countries

It was rather hefty but given that it’s a 20000mAh power bank, that’s expected. Roughly about a phone size though obviously a lot thicker. Came with battery charged to about 75% so you can use it straightaway.
Charging seems relatively fast though the last percent from 99-100% seems to be taking a lot longer.
Charging of devices works as expected. However, the USB output (double lightning) has some alignment issues and there was some difficulty slotting the cable in. Though after first time, it got much easier and is now ok.
Overall the build quality looks reasonably good and it looks a good buy.
