How to find the perfect External Battery for Macbook PRO / AIR?

If you as I am a heavy Mac user – you’ll have realised that the battery is the limitation. Especially when you do video editing while not being near a power socket – you got like 1-2 hrs.

Even if you don’t and you maybe have long working days while flying, taxi’s or even on trains. If you try to catch a early flight like I often do – I’m on the road at 4am. And I hesitate not going to bed before 11pm. It’s easily 12+ hours I require my laptop to keep up with me – and I do not take many hours before it’s under 40%!

Anyway – I have been looking for an external battery for almost 2 years. I have bought a number of different DC-batteries with various adapters. All of them worked the first few weeks – but none of them were lasting more than 10-20 times usage.

Then I realised that there was a project on Kickstarter or one of those platforms that had a battery delivering 110/220V AC power (=Normal socket electricity from battery). This immediately caught my interest – but I have never seen them coming to Europe!!

After some more intensive research I realised that RAVpower have made a 27.000 Mah AC battery charger – that also can deliver USB-C power (5V/3A).

AMAZON: RAVpower – AC Battery Charger

If this is over your budget – then there is a smaller version of it. Check out this one:
Cheaper MacBook Battery Charger from RAVpower.

DO REMARK: I haven’t tested the smaller one – but I have read from reviews that your laptop charger should use less than 50 watt (220v) – for it to work stable. So it would be fine with the Macbook Air 45w charger.

So is it really that great in reality?
It’s quite heavy. It’s a solid small box that fit’s fine into my laptop (shoulder bag). I haven’t checked the weight but my best guess is that it would be 1-1.5 lbs (under 1 KG).

And yes – it really does charge your laptop with 220 v. So I have made some test with my laptop being on 100% – and then do heavy video editing. This will normally get the battery to get down to 99% once in a while (with normal socket power) – and the battery has no other behaviour.

For the use of the laptop – it provides as reliable electricity.

So how long does it last?
I’m currently testing this!
But as soon as I have better information – I will let you know.

Test 1:
Charge a iPad Air 2 – from 20-100% while being used for light browsing. This takes 1 bar out of 9.
The charging speed feels like truly 2.1A output – but I don’t have the tool to measure it.

I will be performing my test on this:

Test 2: 
Charging my Macbook via the 220v 65w charger (original) – battery was 100% – and working heavily with 10 applications for 3 hours and 17 min – before it switched of.

Test 3: 
Charging my Macbook via the 220v 65w charger (original) – when the battery was just 9% – and still working quite heavily – but no video editing. It lasted for 2 hours and 53 min – and left my laptop at a 100%.

Conclusion is clear – it’s not a monster – but a helpful piece of equipment to extend your laptops battery life.

So what is this box so great for?
I’m often on very long transportation situations. This means Cabs (longer journeys), flights (=airports without access to sockets), conferences and to work on site with clients without having easy access to sockets.

My laptop battery will normally take me between 3-6 hours usage depending now what I do – and how good I am to close applications.

What is truly amazing about this product – is that it has such a large capacity (yes it doesn’t last forever) – but even when it’s flat – it charge fast – in just about 2 hours. The charger look small and silly – but it’s pretty damn fast. Even one day when both were flat – I could find a socket in a airport and plug both my Laptop and this battery in – and in just about an hour and 10 min – it got about 60% on the battery – and roughly the same on the laptop. From the 60% charge it was letting me finish my charge in the plane + leaving me with about 40-50% battery on the battery box.

It is great for the laptop life where you don’t have a stable office 5 days a week.

GET SHIT DONE – What’s the secrets?


– Aaron Levie, Box

It sounds so simple, yet it can feel so hard!

Throughout my life, I have had many periods where I’m shocked over how much I have accomplished – and on the other hand how little I had accomplished.

And I have tried to break this issue down, to try to find out why exactly that I can sometimes achieve 5-10 times more than other times – when the time spent is the same?

First I had to declare that the most valuable asset in my life (except my wonderful wife and son), is my time. I can’t get time back. Every minute there is passing is a moment that I can’t buy back – no matter what I will accomplish in the future.

So with that in mind, I have to start respecting the day much more. Not just setting goals, but accomplishing them.

I’m such a cloudy person that, I sometimes find it hard to get them dirty and productive. I love the broader thoughts, planning, researching, etc. But when it comes to actually bringing it to life, I find it hard to find the energy – even though I love the process of creating.

What I have found out is that I need to have certain tool to help me controlling these processes. So I started to use Trello for all broader thoughts and just things that I do need to share with other people – so any kind of team work-related.

And for the things that are 100% on me, including repetitive tasks that need doing either daily, weekly or monthly simply goes into Todoist.

And for things I can’t miss – so either tasks there is a deadline on – or phone meetings, etc. is always scheduled into Google Calendar (which I use the Business version of called: Google Apps).


Google Drive vs. Dropbox

Hi there,
I have been a reliable Dropbox user for ages, and I must admit I have been loving it.
But I have now given my self the challenge that I need to try out the Google Drive. I did try out Google Drive when it was new, on Windows 7 – ages ago – and the client keep breaking down.

Now the Windows is replaced with a Macbook Pro (And OS X) – and I now believe it’s worth to give it a try. After moving to London, I do spend a bit of time in the Google Campus London, close to Old Street/Moregate – and that gives like a naturally curiosity to just try Google’s stuff out.

And since Google provide FREE WIFI with over 200 mbit upload – so I thought it might be a good idea to try it out. As we speak my Dropbox have just passed 300 gb data – a good mixture of documents and pictures – so I hope this also gives me a chance to try out Google Docs more seriously – and see how it works.


As you can see it takes some time – but I will give it a ago – and update this post in a few days.

UPDATE – 24 June 2016:
I have to admit, that I have now tried Google Drive. And yes I did get my 150 gb files uploaded – until I got to my photos – and I tried to use Google Photo Import – and I must admit that it’s a bad solution. It do ONLY upload JPG – and not my videos.

Also from Dropbox I love the way it’s just so smooth to share files – and go back to a earlier version of a document you worked on – with Microsoft Office integration – and Google just doesn’t have these features.

So where the plain file synchronization is fine then I don’t feel they can charge the same price as Dropbox for the service – not yet at least.

WhatsApp on a iPad without jailbreaking it!

Yes, let’s just admit it – it have been a huge weakness from the pure beginning that WhatsApp haven’t bothered making a solution for iPad and other tablets – so you easily can message your friends and family. At least now they have made a half-OK solution online. It does work a bit weirdly as it still depend on live access to the SQlite database on your phone, to actually let you see your messages – or chat. A really weird way of doing it, which probably just turns out to be security wise. But if they would have had what it takes to convince their users to register with an email/password – then the problem would be solved – and they could make a native app for tablets, fully synchronised from a central database.

Anyway, here is a fully legal mini-hack, of how you can use Whatsapp on your iPad, without doing stupid things with Jailbreaking it etc.

Hey! Did you just call it stupid to jailbreak devices?
Yes, I did indeed. When you choose to jailbreak your devices, you also allow the creator of Jailbreaking to install a backdoor to your phone, and you will have full access. Try to do it, turn off Mobile data, put a network monitor on your Wifi, and try to look at the traffic. No kidding, that it’s free.
