What is it?
We've all been there. That sinking feeling when you are still miles from home and look down to see that your mobile phone is almost out of juice.
Recent research by O2 found that half of us suffer from what has been dubbed FoRo (fear of running out) when it comes to battery life. This is where the Griffin Reserve Power Bank could be just the ticket.
Good points?
With charging ports for both tablets (12 watts) and smartphones (5 watts) there is ample capacity and power for most needs.
It crams in battery cells but doesn't feel bulky or overly heavy and can easily be hidden in most pockets or bags.
The unit's 18,200 milliamp lithium-ion battery is recharged via micro-USB input and takes around five hours to complete.
This should provide seven full smartphone and close to 55 smartwatch charges.
The device has a handy charge indicator system with four LEDs. You start with full illumination and as you use the bank, the lights go out one by one until you need to plug in and replenish its supply.
Bad points?
The design is a little bland. It's also on the pricey side of the power bank market.
Best for ...
Those with many devices to charge on the go as usage is simple and two gadgets can be hooked up at the same time.
Avoid if ...
You can't afford to have two power banks in rotation for when one is charging. You may be better off with a quick-charge device such as the Aukey PB-T10.
Score: 8/10.

Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
