Power in your pocket when you need it

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.

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?

Bennie, South Africa. 17 March 2017

Great product and good value for money.

Henz, South Africa. 21 March 2017

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

Kevin, South Africa. 19 December 2016

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

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.

jadon, South Africa. 15 November 2016


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

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. 6 October 2016

Great product

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.

Linda, South Africa. 29 December 2016

Little heavy but works well. Good product.

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.

Ayanda, South Africa. 1 November 2016

stopped working completely after a few months. Really disappointed.

Jaques, South Africa. 4 January 2017

Very happy with this power bank makes life a lot easier

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.
Charges quickly. No regrets.
