I had a problem and the customer service center answered right away. I was unsure about some charges and the team was very transparent in their explanations and came up with a solution.

Customer servises were fantastic and helpfull

Excellent, very useful

I was so happy to have Joos at the hospital emergency department to charge my cellphone.
When it's an emergency, you leave your place ASAP and leave behind all the accessories you might need, like your charger.
The reason I gave 4 stars is because the power bank lost its power faster than it should have. Dropping from three lights to one in almost 15 minutes just doesn't make sense.
But, I contacted customer service through online chat and had a great and prompt conversation.
Overall, I was really satisfied with their services.

I’m at the A&E in University college hospital , why after less than 2 hours of use have I been charged £18 ?!!!, this is obsurd , there is no number to call to speak to someone just a general inbox that will probably get ignored while they’re profiting of our struggles !!!.

Would give zero if I could!! Charged £33 as said I had pack for 16 hrs even though it was returned after 2 hrs . Customer service shocking . DO NOT USE!!

Had a very bad experience in Pavilions shopping centre, the machine is more than happy to take your money but the return mechanism was broken meaning I will now be charged 35 euro for what I intended to be an hour long quick charging session. It is a gamble as to whether or not the return machine will be workinh and I noticed on the machine there were a good few charging bricks missing so this may be happening to others too. It seems the machines may not be checked regularly enough or they may only come out once a complaint is put through. I can barely afford this to be honest so I was very exasperated when this happened. I had no other option as I was stuck there late with a dead phone. Unfortunately I cannot go back to return it as I have a disability that means if I go out for a long day I have to rest for up to 2 weeks after and I am mostly housebound so I will not have an opportunity to try to find an alternative station. You are almost better off going into a pub and getting a seat and asking will they charge your phone if you buy a pint. This was my first experience and I will not be using these stations again. There is no instruction on the screen as to what to do if the mechanism isn't working and you are pretty much screwed as management tells you they dont own it the company does and they dont know anything about it. Not their fault really but if I had known there is basically no recourse if the return machine doesnt work aside from driving around to find another one which I cannot do, I would never have used it. By the time im able to go out again I will be charged the late fee so I may as well keep it. It charged quite slowly to be honest too lol!
Edit:
I have already emailed you the day that I left this review. This was nearly a week ago now.
Edit: still no reply 19th of March.

Utter rip off, charged me £36 and it was never returned even though I only used it for about an hour and returned it well within the 24 hours, eventually got £26 refunded (gesture of goodwill they reckon)... but had to pretty much beg for it!!

Update 27/02... and whaddya know, I didn't even get the £26, for some reason they gave me £20, so I am £16 down!! DON'T DO IT

I had no charger so I said I'll try this and see how it goes and I loved it use to get charger and easy to return it it was actually cheaper then I thought I would recommend it to anyone that needs a charger for phone or iPad ..very satisfied I'am.

rented on in a hotel for the night becaus ei forgot my chrger, took it back in the morning and it chrged me £33 when i only had it from 11pm - 9AM wtf this is crap

Absolutely disgusting. How can this company be allowed to operate in the A and E of a hospital.

My phone ran low due to the huge wait I had in the hospital so I rented a power bank from a Joos machine for less than two hours. I returned it only to find I’d been charged the purchase fee on £36.

Preying on the unfortunate position being with my mother in law and a suspected heart attack.

EDIT: having received the below response, this should be made clear at the point of rental. One week later, I’m still without any refund.

I’m amazed you’re not being investigated.

A really useful facility in a hospital ER, where often you are waiting a long time, and being able to rechange phones easily is a real boon. A great idea and good service.

I was in hospital and used the charger for 3.5 hours and was charged £17. How outrageous is this when they say it’s only like £2 or something for an hour. I’ll never ever use them again. For that amount if money I could have bought a power bank. Rubbish

Absolutely shocking company with zero customer support and no morals.
Returned power bank to the main stand but my 13 year old daughter is getting continuous attempt on her bank card for a fee of £36!

The bank was returned.

Formal complaint logged and after repeated information still no resolve.
Disgraceful behaviour towards a minors Go Henry card!

Ombudsman & trading standards contacted.

I used Joos in The Gym, it genuinely saved my day. I decided to keep my power bank & it’s probably the best (accidental) investment I’ve made to date!

I used Joos on a night out, woke up in the morning and saw a £36 charge on my card, contacted customer service and was told as long as it was returned the charge would be refunded. I got it back in 2 days. Responsive support team and overall a fantastic service!!

Very good power banks, Have different leads for different uses. They have amazing customer service on top of that.

Charged me £36 for one hours use and returned it straight after! Had this 'holding fee' deducted from my bank account for a month now, chasing their 'support' team for 2 weeks now to get my refund, takes them days to reply. I'm really not getting anywhere with them!! Can see it's happened to countless other people so glad I'm not alone. Maybe if I leave a review, they will take my refund seriously... considering a dispute through my bank as it's like emailing a brick wall.

Great customer service. Issue resolved swiftly.
