joospower.com Reviews 

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.

Used Joos power bank when my wife was in hospital. Great service as she relies on her phone for her diabetic glucose monitor. Unfortunately in tbe traumatic situation I failed to put the power bank back correctly and was charged for not returning it. I contacted Joos and even though it was my mistake as a good will gesture they refunded part of the payment.

I was at the hospital and already feeling very stresses when I realised my phone battery was running low. Finding a Joos Power station nearby was a huge relief. The process was quick and my phone started charging straight away. Saved the day

Whilst in very poor health, vulnerable and in need of my phone which was low battery - I STUPIDLY trusted and made use of a power bank hire service I was signposted to.

This service being JOOS RENT A POWER BANK.

Showed fee as being: £1 unlock fee + £3 for 30mins (with a hold fee on bank card of £36 until the power bank was replaced after use).

Purposely the powerbanks are weak and will not effectively charge phone up much; certainly not in 30 mins - so this is a clear opportunity for a scam.

Upon using and replacing the hired power bank, and returning home - I was horrified to see multiple deductions made from my account (listed under name 'Joos' and 'NYX/JOOS'

**********************************
I STRONGLY ADVISE ANYONE USING THIS SERVICE, WHICH LEAVES THE USER OPEN TO BE FINANCIALLY ABUSED AND SCAMMED, AND CAUSE STRESS, UPSET IN ADDITION TO LOSS OF MONEY.

NOTE: ¹Trying to get your money back is hit b miss, an time and energy consuming, as you will have to provide numerous requested bits of info as evidence and even then you will not be fully recompensed and may never get a penny back.

NEVER IN THIS LIFE OR THE NEXT WILL I EVER GO NEAR A JOOS MACHINE OR ANYTHING WITH JOOS WRITTEN ON IT!!!

I had an issue where someone else kept the power bank I rented, and I was charged the maximum. I contacted JOOS and they responded politely, helped me locate the rental, and issued a partial refund. I really appreciate their understanding and assistance.

Amazing customer support, and a great service for those in need of asap power assistance, trapped in a hospital for example.

I had an issue with returning a power bank and the time charge continue to run. The team on the chat helped me resolve this and was very easy for use

Like a lot of other people using this service, I believe that the Joos setup is little short of a scam that uses sharp practice to prey on unsuspecting customers. I rented one of the units in the Stag and Hounds pub in Bristol. I had difficulty returning the power bank so I asked the barman to help me. He did so and confirmed that it had been returned correctly and that all was well. However I have started getting extra charges taken from my credit card. When I contacted the company they claimed that the power bank had not been returned and wanted me to provide proof that it had been. I am now in a different country and they refused to verify themselves with the venue that the unit had been returned. All I can say is BEWARE!!!

I am at the hospital and rented a power bank and I have been charged 2 x £36 I am fuming

Like everyone on here has said this so called company are nothing but a scam. They should be utterly ashamed of themselves. I was at the children's hospital at Stoke-on-Trent 20th Nov with my poorly grandson my phone was getting flat so I used the charger. BIG MISTAKE. They have taken a extra £24 out of my bank. Tried to contact them with no ajoy. Iv contacted my bank to make sure they don't take anymore money out. After all these reviews surely something should be done.

I so wish I’d read these reviews before deciding to rent one of their “rental” power packs at our local hospital A&E (Epsom). We had been there 8 hours and my phone had died so I needed to get a bit of charge. I used it for just over ONE HOUR and returned the unit according to the instructions which the unit confirmed.
I have been charged £36 - like several other people - and the company claims the unit wasn’t returned or not returned “correctly”. I spent an hour this morning on a ‘live chat’ with their customer services who just blamed me for doing something wrong. This company HAS to be completely aware that the units it possesses in its machines and the number it claims people bought/did not return, does not tally and hence that they are wrongly charging a lot of people. This is fraudulent and the company should be investigated. It’s all the more shocking when you realise that the units are deliberately placed in hospital A&Es so they are exploiting people at their most vulnerable moments.

Fees constantly increasing, timescales reducing, data for available vending stations more often than not is incorrect, customer service is AWFUL - different agents ending mixed messages.

Avoid!
