Reviewing the RAVPower 26,800mAh Portable Powerbank Charger

Having used a few different powerbank models over the years – mostly cheap models which barely gave a reliable (nevermind fast!) charge, back in 2014 I decided to upgrade to the best rated powerbank I could find. After lots of research, I decided on the popular 16,750mAh model from RAVPower, which promised to charge an iPhone 6 just over 6 times.

To offer some comparison, those small powerbanks only have a capacity of ~2,000mAh. For perspective, the iPhone 7 has a 1,960mAh battery. So while they look handy, they’re only really suitable as an emergency backup rather than for more regular use.

It served me well and was a great size, however when going to festivals it only just lasted (since I was usually working there from 6-7 days and using my phone a lot). So after seeing the RAVPower 26,800mAh powerbank in Amazon’s Black Friday deals, I decided to upgrade – the great price compared with seriously good reviews made it an easy buy!

I ordered it on Saturday and received it on Tuesday with free delivery (I don’t have Amazon Prime at the moment).

Accessories included too!

It includes two USB to microUSB cables (one short, the other long) for charging the powerbank.

Looking at the tech specs, it can provide up to 2.4A power to each USB port. A regular USB charger would provide 1A of power, so it’s more than twice as fast to charge from the powerbank than a mains to USB plug.


Overall, a great device. It has a solid, robust feel to it, without being so bulky you can’t take it with you. I could easily carry it in side pocket of cargo trousers/shorts or throw it in my backpack.

On a side note, buying through Amazon takes away any risk of the item becoming defective – even if you’re out of any official warranty period, in my experience they’ll offer a replacement or refund, even if you’ve had the product for a few years.

P.S. Stay tuned to my blog for an update on the device’s performance.

Adventures with WiFi-controlled RGB LED strips

I’ve had a few 5m rolls of 5050 RGB LED strip that I haven’t done anything with, so decided it was time to do something. So I ordered a WiFi LED strip controller (from AliExpress) which arrived after a few weeks.

Once connected to my home router, I can control the colour, brightness etc from my iPhone, as well as setting timers. There are also other modes such as flashing the LEDs to the beat of music (either by playing music within the app, or from my iPhone’s microphone).



I ‘mounted’ a 250W PSU (with duct-tape) above my door-frame, wired it up to a mains connection, with the 12V output going into the WiFi controller and then the LED strip.

The makeshift mounting!

Though the LED strip is backed with 3M tape, I decided to initially use small pieces of duct-tape so I could see if I wanted to make it a permanent feature.

So I set about taping it around the coving on my bedroom ceiling to see how it’d look.

I’m quite impressed with the end result!

Amazon’s ‘On-The-Box’ Marketing for The Grand Tour

Over the past few months, I’ve felt bombarded with advertisements for The Grand Tour. Shown prominently on Amazon’s website, on other websites as display marketing, as well as on digital signage in London, I’ve been aware of the upcoming show on Amazon Video for some time now.

Anyway, after placing an Amazon order recently, I got this box.


I’m guessing the intent of this isn’t just to portray The Grand Tour brand, but also grab people’s attention. At first glance, the box looks roughed up/damaged, so it draws your attention – at which point you’re forced to see the GT branding.

It makes sense really – back in 2013, Amazon were shipping 608m orders per year. All of these are potential advertising opportunities. They’ve already added flyers inside the boxes for a few years now, so why not take that one step further and brand the outside of the box.

Will this be a whole new marketing channel? Amazon OnTheBox™, where you pay per thousand impressions (boxes)? Ha! Either way, I thought I’d share this with those who might’ve not seen this.
