Great value, with a ton of features, and charges fast.
23 January 2019
Works well for charging virtually any device you can think of. Charges very quickly, and the display is extremely useful, shows current battery levels, and Voltage and Amperage output when charging external devices. Weight isn't too much of an issue when compared to other 20000mAh batteries, is about 400g. Does seem to be very finicky in actually charging at max output though. Tested with a good quality USB to C cable, on a few different devices (Switch, Note 9, and a Huawei 10 Pro), and it seems to max out at 5v 2a on both the Switch and Note, only going up to 3.0a for the 10 Pro. Thankfully though, that's about the only issue I have, it's otherwise fantastic. It does have pass through charging too, allowing you to charge multiple connected devices while simultaneously charging the battery. Great option for a travel charger.

Capacity good but no 2 amps output as claimed

When I used the Romoss Sense 4, Model PH50 power bank to charge my phone, which is a Samsung S9, my phone app showed it was receiving only around 1 amp or less.
To test the power bank output I connected it to a USB meter with an adjustable load and the results I got confirmed what I already knew.
The power banks "1 amp socket" it showed 4.97 volts at 1 amp load which was close enough.
However, when I applied a 2 amp load to the "2 amp socket" the voltage dropped to only 4.84 volts. When the I lowered the load from 2 amps to 1 amp socket it performed around the same as the 1 amp socket at around 4.94 volts with a 1 amp load.
If you only need a 1 amp output power bank it is okay, if you need 2 amps then look elsewhere.

Great for travelling, offering good capacity, but small enough to be portable. I love that it has two usb ports, because i often have more than one device that needs charging. It keeps all my devices topped up through out the day.
It is great to have it charged ready for when you might need it, there is nothing worse when you are about to go out and you see your phone battery is flat, just take this with you and top it up.
It also charges very quickly.
I have no hesitation recommending this to anyone.

Very impressed with my upgrade, the two charging ports makes keeping up with all online activities run smoothly without missing the important things "To Do" I like I can stash it in my handbag charge on the go and when listening to the portable boom box and needing that charge to keep the sounds pumping. Led numbers makes charging/downcharging easy no more guessing or figuring what colour represents flat.

I had one power bank before but it didn’t had long charging life and took too long to charge. But this power bank is amazing with charging my phone faster. I like it’s colour and the two USB ports to charge my phone and iPad together.

I am very pleased with this purchase, it's made of good material and you can feel the quality. It can change two devices at the sime time, which is really a plus and it does not over heat. Absolutely a must buy for this price and considering the capacity.

Compact power bank ideal for motorcycle travel. Easily fits in breast pocket while charging iPhone and helmet comms on the go. Unit doesn’t get too hot.
