Product Description

Product Description

The successor to our best selling PortaPow Quad, we've improved it in all the big and small ways you've asked for. Its now smaller, more powerful, has interchangeable plugs, faster iPad charging, a unique colour and shape LED to let you see at a glance when each device has finished charging. No LEDs are on when the charger is not in use so its less distracting, and we've moved the USB sockets to the top so its easier to connect your cables.

High Power USB Wall Charger which charges upto four smartphones, tablets, sat navs, ebook readers, and the many other devices which charge from a USB socket. Most devices charge at a max of 1 or 2A, so the Crystal's 4.2A is enough to charge most combinations of devices at max speed. An 'iPad Fast' gives high speed iPad charging and works fine with most other devices, the other three sockets are built to the universal USB standard for high speed charging. The full 4.2A can be output from any single USB socket.

Wide Compatibility charges Apple products, Raspberry Pi, micro USB devices and all other devices designed to the charged from a USB socket at max speed. Some versions of the Samsung Galaxy Tab / Note do not follow the standard USB specification so will not charge using the supplied cable. Search for B009ZQKMDA for a solution. Difficult to charge devices such as the Asus Transformer work fine with the Crystal.

Status LEDs Each USB socket is represented by a matching LED, each with a unique shape and colour. At a glance you can see when your device has finished its main charge and has switched to trickle charging as the LED will turn off. The charger shows that some devices actually continue to charge after displaying 100% on screen.

Light and Compact 6cmx4.3cmx3.3cm excluding plugs, 135g, plugs straight into a power socket with no external power cable needed.

Short circuit and over current protection, input of 100-240V.

I bought this to replace the older PortaPow 2.5A quad. That performed well for our whole family for over a year before I gave it to my son, who is still using it without any problems.

The newer product is smaller, more flexible, more convenient and has more discreet lights.

It charges the family's two Samsung Galaxy Note IIs and an S3 more quickly that any other charger we have. There is no noise/heat dissipated when the charging devices remove their load (other chargers do that). Seems to be a good design, like the previous PortaPow.

I've not had it long but first impressions are very good. Highly recommended.

I needed a multiple charger to replace the 3 or 4 I have for each of my many gadgets. This provides more than enough power even when 4 devices are connected at the same time. Each triangle at the front of the charger lights up with a different colour and denotes when a device is charging. Once fully charged the light goes off and the device is then topped up when required. Another good feature is that the USB connectors are at the top of the charger, helpful in Premier Inns (and other hotels) where the sockets are so low you cannot always get a normal charger to plug in. Overall a great product.

Seems to work exactly as advertised. I have charged my iPad, two iPhones and a Kindle with this all without problem. The most I have had on charge at a time is the iPad and two iPhones and all three seemed to charge as normal.
Going to Spain for a week soon so the European adapter will come in handy. It also has two other adapters so looks like it will work pretty much anywhere!
I use this on my kitchen worktop and it has freed up some sockets. Because it is at chest height, it is easy to see the indicator lights and know when things are charged/charging/trickle charging.
Update. 3 months later and it's stopped working. Bit of a faff getting a refund which meant I had to Google how to get a refund. Ended up having a web chat with a very helpful chap who refunded me and provided a free return label. Disappointed that it broke cos it was a good item :-(

It’s strange how worried people seem to be over LED’s the brighter the better, but agree with the other buyer if your worried about it lighting up the house you will be OK.
It charged my iPad Air in about 7 hours fully from 1% battery life, I have Portapow’s previous charger as well, very nice products indeed.

Keep this in the car so I have it wherever I go. Bought it as I came to the realisation that not all USB cables or USB chargers/receptacles are equal, and some charge MUCH faster than others. This really does increase by some margin how quickly I can charge my phone when visiting family or friends. It's a bit big and brutal in terms of portability, not a problem if used in a stationary place as a family charger in the home though. For my use-case of having it on-the-go though it means me carrying it in the supplied packaging in the collapsed form (the socket part and the adapter part can be separated to use different international socket types which come supplied rather handily). Build quality is fairly decent and as I have various PortaPow products now I've come to trust the brand's equipment (I also have various car chargers, charge-only cables, etc).

This review goes beyond what I have said in my video review.

I bought this not for travel but because there can be competition in our household for chargers. I bought it to have 4 sockets on one charger.

I have tried the fast charger on my iPad and had no problems - it works well. It is great to have a fast charger as the iPad takes a long time to charge on a standard socket.

The 4 LEDs are muted which is great. I have another charger, the LED power light of which is far too bright - it disturbs you if in bed. Not this one.

Unlike another charger that I have, the LED goes off when the item you are charging has ceased to draw any current, i.e. the LEDs give you an indication of the power being drawn by the device, as opposed to simply indicating that the power to the charger is on.

Personally, I do not leave this charger plugged into the wall because dust will get into the 4 USB ports which can't do it any good in the long term. I have read before that when USB sockets no longer function, it is sometimes due to a build-up of dust and dirt.

The fact that this device has its USB sockets on the top can make the difference between being able to use it and not. I have found that some hotels have mains sockets just above objects which cannot be moved. This means that if this device had its USB sockets on the bottom (like its predecessor), you would be unable to plug anything into it. Therefore having the sockets on the top can be critical instead of a matter of style and convenience.

When travelling, I always take a spare USB charger (one of my old single-device chargers) plus a spare cable (e.g. iPhone & Kindle leads) due to Murphy's Law.

Fed up with having one USB charger for my mobile, other for my tablet, another for the USB speakers and yet another for my USB clock, I opted for one of these.

Given that the phone and tablet chargers are 1.2A and 2A respectively, this was a perfect replacement. The cables are now tidy, organised, and easier to reach on my bedside table, and the charger LEDs are really useful to see what is still charging without having to flick screens on for a few seconds.

I have already recommended to several friends and colleagues who (like me) have a mass of USB items lying around.
