Power in your pocket when you need it

Jarques, South Africa. 20 May 2017

Super product at a great price! Bought 2! Getting a lot of value out of it. Super happy with it!!! Charges my devices again and again and again!

THEO, South Africa. 7 November 2016

Switches on but then for no reason switches itself off after about ten minutes. Not impressed. Will be returning it.

Andre, South Africa. 13 June 2017

Great powerbank. Charge my phone many times.
- Heavy, because it's a big battery.
- Take long to recharge because it's a big battery.

Shanleigh, South Africa. 22 May 2017

Love it :-) Able to charge my smart phone numerous times from a single charge of the power bank. And another great feature is that you change charge 2 devices simultaneously :-)

Tanya, South Africa. 9 August 2017

Excellent product. Liked mine so much I've bought it for a couple of loved ones too.

Joe, South Africa. 9 November 2016

Great product. Works well, slightly bigger but what do you expect for a power bank that holds this much charge?

Mo, South Africa. 25 July 2017

Great product. long-lasting and get quite a number of charges out of it. Perfect when doing long hours.

Bennie, South Africa. 17 March 2017

Great product and good value for money.

Brian, South Africa. 14 November 2017

This is a big power bank so be aware that it is heavy and takes a while to charge. However, it will give you multiple charges of whatever device you're needing to charge. Before being swayed by any of the few negative comments here, read up on the pros and cons of polymer batteries. Also don't expect to leave the power bank in a drawer for two years and then use it - this item, like all batteries, wants to be used!

Henz, South Africa. 21 March 2017

Premier power bank. Fast charging and holds many charges. Great buy.

Bafana, South Africa. 11 October 2017

Mine just spotted working. I have not been using it often, maybe once in 4 months that is if there is loadshedding or something. I think I bought mine in 2015 thinking it is an investment. When the storm struck about 2 days ago here in Ekurhuleni, the power bank didn't save the day as expected. What a waste of money. It shows battery as full but switches itself off after about 10 seconds. Utterly disappointed.

Kevin, South Africa. 19 December 2016

Large capacity
charge quickly
charge cellphones quickly
large in size and heavy

Marco, South Africa. 28 April 2017

Charged my phone fully and didn't even put a dent in the bars on the bank! Really happy!!

Vanessa, South Africa. 8 December 2016

Great product with super fast charging, definitely worth the money!

Neil, South Africa. 30 November 2016

No complaints so far, does exactly as it says on the box.

Jedd, South Africa. 27 April 2017

Not too bad, lasts the day charging my Samsung S7, but it does take the whole night to charge.
I have a generic Powerbank, with 5000MAH, that charged quicker and also lasted the entire day.

Manages to charge an S7 about 1.5 times before needing to be put back on charge.

Ryan, South Africa. 14 September 2017

It's a beast of a thing, but it delivers and is built like a tank.

My only crit is that with it being a top-end product it should at least have intelligent charging ports like some of the competitor products.

Jason, South Africa. 12 June 2017

this powerbank is really worth the money. The fast charging capability is amazing and charges almost all devices. I would highly recommend it

jadon, South Africa. 15 November 2016


Adrian, South Africa. 29 September 2017

It is not a bad product but I did expect more. I can charge my Samsung S8+ 4-5 times, was expecting 8-10 times. It has two USB ports but unfortunately it only comes with one micro USB cable! Also, the cable has the old Samsung micro USB so I cannot charge my new S8 which has the new micro USB port.

Louis, South Africa. 2 May 2017

Works like a charm ! So happy with my purchase!

Lucien, South Africa. 11 November 2016

Very Powerful, does what it says. Last forever.

ETC, South Africa. 28 February 2017

Excellent powerbank. Hefty but worth it. Charge time for recharging it needs to be planned for evenings and night.

Dawie, South Africa. 1 February 2017

My son is over the moon chuffed. A bit bulky but loads of power

Gabriel, South Africa. 23 May 2017

Greeeeeeeat product - A bit heavy but super worth it.

Sonja, South Africa. 2 May 2017

A little heavy, but excellent!

nerika, South Africa. 11 October 2016

Great product. I was skeptical about it because of the low price but I have been using it for days now and only on the initial charge, charges my phone pretty quickly as well. It is a bit bigger and heavier than I thought it would be although that makes sense for a 20000mAh.

salegga, South Africa. 12 December 2016

I have used this product while driving from Montague Gardens to Cape Point and only got a 6% increase in battery life for my Samsung S5.
Not impressed.

Great product!, South Africa. 26 September 2016

Picture does not match the one delivered. It has the normal plastic finish as the other non Li-Po devices. Keep in mind it's 20 000mah and has to be quite big.

gina, South Africa. 27 September 2016

Excellent product. Loads ipads, cellphones, etc and battery stays alive for weeks when not in use. Definitely recommended

Deviesh, South Africa. 20 December 2016

Hi All, although this is different from the other polymoss units, it does a great job. quite large but managed to charge 1x 4800 MAH battery and 1x 6000 MAH battery.

i wished they had kept to the polymoss 5 & 10 look, those are alot slimmer and pocket friendly.

Reddy, South Africa. 1 November 2016

Not as in picture but still worth it.

Nkosenhle, South Africa. 8 June 2017

Great product

Anthony, South Africa. 9 June 2017

It looks big, but the same width and height of samsung note. Fantastic.

Fidelis, South Africa. 14 February 2017

This product does provide a reliable power backup for electronic gadgets, e.g. cellphone. It can store power for up to seven days without needing to be recharged. The only thing I find boring is to recharge the power bank itself, which takes quite long (about 10 hours!) if the power bank is flat. Anyway, recharging the power bank is something I now do while I am asleep.

I highly recommend this product to anyone looking for a reliable power bank.

Xenia, South Africa. 2 May 2017

Excellent and convenient travel companion. Charges quickly and ensures that I'm never without my devices again due to flat batteries.

Linda, South Africa. 29 December 2016

Little heavy but works well. Good product.

Cate, South Africa. 21 July 2017

It's a bit bigger than my smartphone, but holds enough juice to get me through a Pokemon event and at least a couple of more charges. The cable that comes with the powerbank seem to wear out fast unfortunately, but the powerbank itself is worth it if you want to ensure you always have a fully charged cellphone. I was also able to run several other USB devices such as USB lights, USB fans and a USB UV light during travels from it.

Victor, South Africa. 11 January 2017

This is second Romoss Power Bank that I have bought - the first burnt out while charging it for the second time. I have used this charger to charge a iPad and Google tablet with hardly any decrease in the capacity of the Power Bank. For its price it is a good buy - I am just worried that it may also burn out while charging.

Yolanda, South Africa. 20 January 2017

A bit bulky. But amazing performance. It's runs 4 days without charge

Elmarie, South Africa. 2 March 2017

takes long to charge... but its worth it.

Henri, South Africa. 13 June 2017

power forever no more flat battery s
power forever no more flat battery s

Johann, South Africa. 28 June 2017

I usually get about 4 charges of my phone when the power bank is fully charged, and it can charge two devices at a time. The unit is much larger than the average power bank (think about the size of a scientific calculator, just thicker and heavier), so it's not as portable. Charging it to full capacity takes long, but that's to be expected.

Couple this with a mini-power bank for when you are on the move, and you have the perfect portable charging solution.

Ayanda, South Africa. 1 November 2016

stopped working completely after a few months. Really disappointed.

Damian, South Africa. 15 June 2017

Very good
Charges my iPhone 6 up to ten times and takes the power bank the whole night to charge.

Jaques, South Africa. 4 January 2017

Very happy with this power bank makes life a lot easier

mms, South Africa. 27 June 2017

Quick delivery. Great device! Not as big and heavy as I had imagined and it holds great power. Charges my phone very quickly. 101% so far.

Sibongile, South Africa. 8 December 2016

Slightly heavy understandably so since its 20 000mAh,but I'm enjoying the longetivity of the powerbank.Happy with the product so far.

Devlin, South Africa. 12 December 2016

Bit bulky, but holds charge for ages and charges anything I throw at it!Only had it a few weeks so can't comment on how long it will continue this performance, but for the moment I can say it delivers as promised!

Stefan, South Africa. 11 November 2016

Amazing device. I would strongly recommend it! I can charge my Samsung S6 more than 6 times with only one charge.

mo, South Africa. 19 December 2016

love it ..used it once so far.and they haven't been any issues... takes long to charge but great

Johan, South Africa. 8 December 2016

A first rate product at a good price. Does all that it is supposed to and more.

Brendan, South Africa. 11 November 2016

Amazing device, battery pack charges quickly and holds charge well, using the 2.1A port it charges my iPhone quickly. Really good value.

rama, South Africa. 9 March 2017

Product is nice

Stuart, South Africa. 6 October 2016

the charging cable stopped working after 3 uses but the manuel says only to use tge original cable.

Edward Ngwako, South Africa. 19 December 2016

So guys fist few days I was super excited with my long lasting power bank but now I'm so sad, it's my second day I'm trying to change my power bank it doesn't charge, it keeps showing one bar but no movement, I don't know if I will get a replacement or what is the process. I need solution urgently please

Maartin, South Africa. 31 December 2016

Great product, definitely worth it to have it.

Joey, South Africa. 15 June 2017

It is bigger (in actual size) than I expected it to be, but I am still very happy with it and it is working ideally for me.

Emmanuel, South Africa. 5 September 2017

This power bank is a life saver...lots of power to last you the whole day especially those of us using big phones with big batteries...I don't regret buying it.

Lucky , South Africa. 18 August 2017
