Review: Anker PowerCore 20100 Ultra High Capacity Portable Battery Pack

In todays modern battery powered mobile world it is very inconvenient to be caught out of charge. Usually when you first get your device it never seems to be an issue but as your device ages the battery never seems to last as long. I have 3 mobile devices and decided it was a good time to buy a mobile battery pack. The first one I bought was mostly dead after one charge of my iPhone 6 Plus. It was time to look for a larger capacity and thats when I found the Anker PowerCore 20100 Ultra High Capacity Portable Battery. I’d bought other Anker products and been really impressed at the quality and thoughtfulness in their design. A list of other Anker products I’d recommend can be found at the bottom of the post. 

Tech Specs

  • Anker in general has some great technology and this product is no different, below are the tech specs from Anker:
  • Ultra-High Capacity: It can charge the iPhone 6 seven times, the Galaxy S6 five times or the iPad mini twice. Recharges in 10 hours with a 2 amp charger, phone chargers (generally 1 amp) may take up to 20 hours.
  • Fast Charging Technology: The trademarked PowerIQ and VoltageBoost technologies combine to deliver the fastest possible charge up to 2.4 amps per port or 4.8 amps overall. Input: 5V / 2A.
  • PowerIQ: Discovers and replicates the charging protocol of the device’s original charger.
  • PowerIQ: Device safely accepts its fastest possible charge speed.
  • VoltageBoost: Detects the cable resistance and adjusts current accordingly to provide the fastest, most steady charge, whatever cable you use. 
  • Certified Safe: Anker's MultiProtect safety system ensures complete protection for you and your devices.
  • Short Circuit Protection
  • Temperature Control
  • Output Voltage Surge Protection
  • Output Current Stabilizer
  • Power Overload Recovery
  • Battery Cell Protection
  • Auto Shut-off Sleep Mode
  • Input Voltage Surge Protection
  • Output Current Limiter
  • Low Voltage Protection

Other Good Stuff

Anker has a superb warranty, a whole 18 months which shows faith in their products. The device also come with a micro USB charging cable and a travel pouch. The pouch is a nice idea to keep your device safe and looking good.

Note: All other cables needed to charge your devices are sold separately. I’d recommend the lightning/micro USB hot swap Spigen cables


My PowerCore goes everywhere with my in my bag, it doesn’t take up much room and I don’t notice additional weight. I’ve used it in many different situations but some key ones have been on a transatlantic flight to top up my devices prior to landing. I’ve used it in coffee shops and even at the top of a mountain to keep charge on my mobile phone. The device is rugged, versatile and highly mobile thats to its high capacity. 


In summary, if you are looking for or considering a mobile power solution then I would highly recommend the Anker PowerCore

Other Anker products I own and I’d recommend include:

  • Anker PowerPort 5: 5 port USB charging hub utilising all of the charging technology mentioned above in a portable hub.
  • Anker PowerDrive 2: 2 port USB charger for the cigarette charger (12V outlet) in your car.

Review: Bose QC25 Noise Cancelling Headphones

Review: Bose QC25 Noise Cancelling Headphones

Note: Ironically the very day I wrote this review the headphones broke! The right hand ear piece died completely. Apparently this fault isn’t uncommon, having asked a few people in my office. All were clear, as am I, that the Bose support is fantastic. One 5 minute call to Bose and they are sending me a UPS label to send the headphones back and a replacement will be sent out. No hassle or questions given!

If you've never used noise cancelling headphones before, or you are seeking your first pair the Bose QC25 headphones will blow you away! I first picked these headphones up on a transatlantic flight back from Houston. I was in economy with the cheap and nasty headphones provided by the airline, the hum of the cabin still clearly audible. I couldn't use my wireless headphones so I was out of options, until I opened the duty free magazine. I promptly ordered the headphones on the plane and within 5 minutes was in noise cancelling heaven. 

The moment I flicked the power switch on the earphones, the noise evaporated. I could now here the plane movies clearly, all the little intricate sounds which were previously masked by the cabin noise. The great thing about the QC25's is they come with a battery and with an airline adaptor to connect to the planes sound system. It means you can use them literally right out of the box.

Skip ahead 24hrs and I was in the office, the very definition of hell, open plan! Unable to concentrate due to the talking in the office I put on the QC25's and again, the noise was gone! I could vaguely here conversations going on around me when there was nothing being played through the headphones. As soon as the music started there was no way I could hear any of my surroundings, bliss!

The Bose QC25's are not cheap, but you pay for what you get. Not only that, but if you do use them in the office environment then they will pay themselves back in terms of increased productivity and stress reduction. These really are one of the best investments I have made with respect to technology, I wouldn't be without them now. Bose has recently released the QC35's which are a wireless version of the QC25. However, if we forget the difference in audio quality between wired and wireless the major drawback is that the battery is not useable replaceable. When I pay over £300 for a set of headphones, I don't want them to have a shelf life governed by a battery. In my opinion, that makes the QC25's a better purchase at this time.

How to Preserve iOS 9 Battery Life: Part 1 Background App Refresh

I've had my iPhone 6 Plus for about 1.5 years now, initially the battery life was amazing. More recently I've noticed that it rapidly drops off, this is in part due to the age of the device but it's also in part due to several factors that I will cover in a series of posts about preserving iOS 9 battery life. I expect these tips will remain valid even with subsequent iOS versions.

Background App Refresh was a feature introduced in iOS 7 and for the best summary of what it does I refer to an Apple support article:

...Apps can continue to run for a short period of time and are then set to a suspended state so they are not actively in use, open, or taking up system resources. They will instantly launch when you return to them. Certain tasks or services can continue to run in the background. To lessen the effect on battery life, normal app background refreshing is scheduled for efficient times, such as when your device is connected to Wi-Fi, plugged into a power source, or being actively used. When Background App Refresh is on, apps that take advantage of this feature can refresh themselves in the background. For example, an app can check if new content is available and download the updates, or retrieve the updated content in the background when it receives a push notification, so the new content is ready for viewing when you launch the app. Apps can also schedule background refreshing based on your location. If you force an app to quit by dragging it up from the multitasking display, it won't be able to do its background activities, such as tracking location or responding to VoIP calls, until you relaunch the app. iOS learns patterns based on your use of the device and tries to predict when an app should be updated in the background. It also learns when the device is typically inactive, such as during the night, to reduce update frequency when the device is not in use.

You will read many articles on the internet that tell you disable all Background App Refreshing to save battery life and others that will tell you not to bother at all as it makes no difference. 

Apple Resource's advice is to go through the list and make a conscious decision as to how much you use each application and how much you'd value it updating whilst in the background. It's perfectly OK to leave apps that you value and use all the time as active due to the intelligent way Background App Refresh works. What you don't want is every single app using it if you rarely use them. Although it was first introduced in iOS 7, apps taking advantage of Background App Refresh will have percolated through over time, which is why you may have a shock when you open up the Background App Refresh found at:

Settings -> General -> Background App Refresh

How to Clear All Apple Watch Notifications in a Swipe and Two Taps

How to Clear All Apple Watch Notifications in a Swipe and Two Taps

I consider myself an advanced user of Apple products, but just yesterday I learnt a trick about clearing notifications on my Apple Watch that I never knew. When you see a red dot on the top of your watch face this indicates that you have waiting notifications. Swiping down with your finger you are presented with a list of all your notifications.

What if you don’t want to read them all but want to clear them ready for new notifications, how do you do that? Here’s how:

1. From the watch face swipe down from the top of the watch face showing all of your notifications.
2. Press on the watch screen and an icon will appear on your screen saying ‘Clear All’.
3. Tap ‘Clear All’ and you are all clear of notifications.

How to Make an Online Backup with iCloud

How to Make an Online Backup with iCloud

In the wake of multiple updates from Apple this week, including iOS updates it is a pertinent time to remind everyone the importance of backing up. You should be backing up your iOS device both locally and online.

Apple has an excellent online guide that shows you how to backup both locally with iTunes and online via iCloud.

But here is a really important message I want to impart on you. iCloud online comes with 5GB of online storage, you need to be aware of this. For your average iPhone user snapping pics and videos this will be used up rapidly. 

Apple has a range of very affordable monthly tariffs for iCloud storage, make sure you invest and upgrade. It will cover all of your iOS devices and ensure that your devices are backed up every night as they are plugged in to charge.
