RAVPower 30W 3-port USB UK wall charger review

RAVPower 30W 3-port USB wall charger
RAVPower 30W 3-port USB wall charger

The RAVPower RP-PC020 is a 30W 3-port USB wall charger that, as the name suggests, allows up to three devices to charge simultaneously.

Each port offers the same output: DC 5V at a maximum of 2.5A, so it should be suitable for charging anything from the most humble feature phone to a smartphone or tablet; I’ve used mine to charge all three without incident. The built-in iSmart technology adjusts the output automatically so that each device charges quickly and safely.

The charger comes packaged in a small, sturdy white box with a simple and attractive design. It already looks and feels like a quality product.

Opening the box I was greeted by the quick start guide (written in six languages: English, German, French, Spanish, Italian and Japanese) draped over the charger, and a friendly “Hello” written on the cover. I like it already.

Inside the box, the charger was wrapped in a plastic sleeve and nestled between two cardboard arms within the box, offering excellent protection for transit or an accidental drop. The only other item in the box is a small card with details about a free 12-month extended warranty.

The charger itself seems solid: this feels like a quality product. The model I have is encased in hard, shiny white plastic with RAVPower written on one side and iSmart on the other. On the side closest to the floor when plugged into a wall socket is written model name and number, input and output values plus various other health and safety icons. The remaining sides offer the UK 3-pin plug and opposite it three USB type A ports.

When plugged in and switched on the USB ports light up, a light blue/white colour, which makes plugging USB cables into it in the dark a little easier — even if you always try to plug it in the wrong way first… oh for when USB C becomes the standard).

One niggle I have with many computer-related plugs is that when plugged into a multisocket block many plugs are too long and so obscure the socket opposite, reducing the number of available sockets by one. Happily this is not one of them: the body of the charger does not extend beyond the height of the plug meaning that you can always plug in something else opposite. The whole unit is really neat and portable; I wouldn’t think twice about throwing this in my bag and taking it with me — it takes up hardly any space at all.

All in all, I am delighted with this adapter. As I’ve already said, it feels like a quality product, I love that the sockets light up, and that it can handle three cables at once means that I now use this as my primary adapter for my smartphone and tablet, with a spare socket for guests or my children’s Amazon Fire tablets. I would wholeheartedly recommend this adapter.

In the interests of transparency: I was sent this product by RAVPower for review. I am not connected to the company in any way apart from having been a former customer.

I’m selling my Psion PDAs

Update (15 August)

My Psion archive has now been sold. This is the first day in 21 years that I’ve not had a Psion computer or book in my possession.

Many thanks to everyone who got in touch regarding these sales, and especially to the lovely Psion enthusiasts who purchased these machines. They gave me a great deal of joy over the years, I hope they serve you equally as well.

Original post

Today, I put my four Psion PDAs up for auction on eBay UK:

Psion Series 7book

Psion Series 7book (Series 7 with netBook personality module)
Psion Series 7book (Series 7 with netBook personality module)

This was the last Psion that I bought—it must have been early 2004. I bought it to take to the US with me on holiday, and for a couple of writing projects I was working on.

It was a Series 7, bought on eBay, and later upgraded to a 7book by fitting a Psion netBook personality module. This made it capable of accepting a wi-fi adapter card (I bought two, one each of the two main chipsets that work well with netBooks).

I’m selling the lot in one bundle:

  • Psion 7book (Series 7 with netBook module)
  • Leathette carry case
  • Psion Series 7 user guide
  • PsiWin 2.3 CD-ROM
  • RS232 serial cable
  • USB to serial adapter (D400)
  • 2 x UK power adapters
  • Psion Series 7 personality module
  • 2 x compact flash cards (one contains the EPOC R5 OS required for booting the first time)
  • 2 x Wi-fi cards (Lucent Orinoco Gold and Buffalo Air Station WLI-PCM-L11GP)
  • DVD containing all the Psion software I collected over the years; I used to sell this online.

Psion Series 5mx

I bought the 5mx shortly after moving to Edinburgh, from Inverness in 2003. It was another eBay purchase and was to replace my Psion 3mx.

I just wanted a new piece of kit. It has a 32-bit operating system, a beautiful clam-shell case, where the keyboard slides out when you open it, and a backlit, touch screen. What more could you want from a PDA?

I’m selling:

  • Psion 5mx 16MB
  • RS232 serial cable
  • PsiWin 2.3 CD-ROM
  • Proporta.com hard case
  • 2 x UK power adapter (one with interchangable UK/Euro/USA pins)
  • Boxed Purple Software Chess software (3.5″ floppy) and manuals
  • Palmtop Street Planner 99 software on CD-ROMs and manuals

See listing on eBay (offers over £45)

Psion 3mx

This Psion was my workhorse for many years. It’s solid and dependable, and I don’t ever remember the screen cable breaking, which was the most common fault these machines suffered. I did have it fully refurbished a couple of times, though, from the dependable POS Ltd in London, run by Paul Pinnock.

Something I loved about the 3mx is how long the batteries lasted. I could usually get about one month’s use out of a pair of AA batteries.

Included I’ve got:

  • Psion Series 3mx 2MB palmtop computer
  • Series 3mx original user guide
  • Series 3a programming manual (OPL)
  • Programming manual (OVAL) and disk
  • PsiWin 1.1 disks and manual
  • Psion 56k infrared travel modem (with disks and manual)
  • 4 x solid state disks (3 x 1MB and AutoRoute Express software).
  • UK power adapter

Psion Siena 512k

Ah! My first Psion.

I saw an advert for the Psion Siena in a copy of MicroMart, I think it was. And I immediately fell in love with it. I pondered buying one for weeks before getting up one sunny morning in my flat and travelling to London’s busy Oxford Street to purchase it at Debenham’s department store.

It immediately became my diary, contacts list, to do list, journal and programming machine. I bought a copy of PsiWin 1.1 (for £80) and connected it to my Windows 3.11 for Workgroups PC (a 386 SX-20).

I used it to write and edit my masters dissertation in 1999.

This includes only:

  • Psion Siena 512 KB palmtop computer
  • User guide
  • A letter from Psion

See listing on eBay (offers over £20)

Programming Psion Computers

Programming Psion Computers by Leigh Edwards (EMCC, 1999)

This book was the bible of Psion computing about 18 years ago. I managed to grab myself a copy in Waterstones bookshop on Edinburgh’s Princes Street, for £29.99.

It soon became quite a rare book, and so the publisher, EMCC, made it available in PDF on their website, as well as a zip archive of the CD-ROM that accompanied it. Many years ago, I gave away the CD-ROM to someone who was desperate for a copy of the original.

The end of an era

I’ve been meaning to list these for months, but only just got around to it now while I have my head in the selling-space as part of the divorce settlement.

I feel sorry to see these go, but they are just sitting in a box in my cupboard and I would much rather they went to someone who got some pleasure out of them.

Reinstalling Windows 10—my process

Trello board for reinstalling software on my PC

About two months ago, I reinstalled Windows 10 on both my desktop and laptop computers. This post is about what I do to make sure the process is as smooth as possible.

Installation files

Something I have done for years (since Windows 98) is to store most of my installation files in a directory.

I store mostly drivers, plus applications that are either rare or that I have purchased. I don’t store applications that update regularly (e.g. web browsers, WinSCP, IrfanView, etc.).

Within my installation directory I organise the files into sub-categories, like this:

Installation files organised into categories
Installation files organised into categories

This allows me to find drivers and applications more easily. It’s also roughly how I organise the installed applications on my Windows start screen:

My Windows 10 start screen categories more or less match how I organise them in the installation folder
My Windows 10 start screen categories more or less match how I organise them in the installation folder

I store these files on a separate hard drive from the one that I install Windows on; I always install Windows on its own drive. This allows me to quickly reinstall Windows without worrying about overwriting the installation files.

I also backup these files to an external hard drive. I currently use a 2TB Seagate Backup Plus drive (USB 3.0).

Trello board

For each computer, I have created a separate Trello board to guide me through the installation process.

I have boards for my desktop and laptop computers, plus my work computer. I also do the same for my Android smartphone.

Everything I need to know to carry out a smooth reinstallation
Everything I need to know to carry out a smooth reinstallation

Each board outlines my backup routine for each computer, any applications or services that I need to uninstall or deactivate before the reinstall, and then for each driver or application I record the steps I need to take, options to select, or any problems that I’ve encountered, etc.

The first few columns on each board outline the order in which I like to install things: drivers first then essential system applications. Within each column, again the arrangement of cards shows me the order that applications need to be installed, e.g. motherboard drivers, graphics card drivers then Windows updates.

I use images on some cards to make it quicker to identify them.

Images help me quickly identify to what the cards relate
Images help me quickly identify to what the cards relate

And as you may suspect, the column names on these Trello board match one-to-one the sub-directory names in my installation folder.

I then use Trello labels to track the status of each driver or application. I can see at a glance which applications I regard as essential and which I install only the first time I require them.

I use red labels to indicate any problems; purple labels tell me whether I need a reboot after installation; navy labels indicate work-related applications; and light blue labels give me a clue as to where to find them.

Labels help me track type of application plus installation status
Labels help me track type of application plus installation status

SafeInCloud

The last piece of the puzzle is where I keep any registration or serial keys. I store these in my encrypted password safe, SafeInCloud.

I use my password safe to also store registration keys for software applications
I use my password safe to also store registration keys for software applications

Conclusion

Since moving to this workflow, I have found the process to be very straightforward. I can track everything using my smartphone using the Android apps for Trello and SafeInCloud, and I can easily record any problems or lessons learned meaning that each time I do this it gets easier each time.

A brief history of Psion PDAs

David Potter is the Psion King
David Potter is the Psion King

Clearing through a number of boxes that I hauled down from the attic, I discovered the following brief interview with David Potter, CBE founder of Psion—the former personal digital assistant (PDA) pioneer.

(Unfortunately, I didn’t record which magazine this was taken from or the year. Maybe you recognise it; if so, please leave a comment below and I’ll update this post.)

Horace and the Psioneers…

The history of Psion PDAs is not quite what you’d expect!

How did Psion get started?

In 1980 David Potter started a software development company above an estate agent’s office in North London. He had one employee, Charles Davies.

So they’ve always made handheld computers?

Nope. They made games for the Sinclair Spectrum. The first flight simulator available for the Spectrum was a Psion product. Later they released Horace Goes Skiing, which was part of a huge series of famous Horace games where the eponymous character fought spiders and dodged traffic.

Er, right. When did the first Psion PDA come about then?

Not so fast! Before the term PDA was even coined, Psion produced the Psion Organiser, virtually creating the electronic organiser industry by itself. Launched in 1984 the first Organiser had 8K of memory, could hold around 120 phone numbers, had a non-QWERTY keyboard layout and lasted a week on its AA batteries. Then came the Organiser II in 1986, which had twice the memory and was the first device to use a solid-state “disk drive” for non-volatile storage. Marks and Spencer adopted it for stock control and British Midland used it for its ticketing staff. There was also a brief attempt at a laptop in the shape of the MC400 in 1988. This was used by British Gas sales staff. Psion was floated on the stock market in that year.

Blimey. But how did we get from there to my Series 7?

In 1990, Psion took over Dacom communications and became Psion Dacom. A year later it released the Psion Series 3, which used 16-bit technology, had 128K of memory and a proper QWERTY keyboard layout. It sold one million units in two years! This success was quickly followed by the Psion 3a with 2MB of memory, and the 3c with 4MB. There was also a ruggedised industrial machine called the Psion Workabout that included built-in short range wireless communications.

In 1996 the Series 5 was born. This device has a 32-bit architecture with true multitasking, 16MB of memory and a better keyboard. 1996 also saw the launch of the Siena, which was a smaller machine, the precursor to the Revo. The Revo itself wasn’t launched until last year, along with the 5mx — an improved version of the Series 5 — and then the gorgeous Series 7, which sports a colour screen, laptop keyboard and PC-card slots.

Where’s David Potter now? Sold up and living in Bali?

No, he’s still Chairman of Psion. And Charles Davies is his Development Director. They now have a £160 million turnover and 1,500 employees worldwide.

Why are all the machines odd-numbered?

The jump from 3 to 5 occurred because the number 4 is unlucky in China. Now that Palm have copied this numbering strategy, Psion says it may release a Psion 16 in the future, just to confuse everyone. Nice.

Source: www.mcu.co.uk, page 87

Of course, they didn’t release a Psion 16. Next up was the netBook, which eventually became the netBook CE running the Windows mobile operating system, plus a Revo MX, and then they iterated on the WorkAbout range for business.

I have very fond memories of my Psion machines. They were great.
