I recently ordered a coolreall 20000mAh power bank from Amazon.  I was really impressed by the speed and efficacy of the service given and in no time at all after ordering my power bank had arrived.  The product was well packaged in a solid box to prevent any damage.


Inside I had everything I needed to get the power bank charged so I could take it on my travels this included the power bank, a micro USB cable and instruction booklet.


This particular power bank is slightly larger than a smart phone and not excessively weighty as one might expect and it is able to charge 3 devices simultaneously.  The power bank will automatically detect and deliver the optimal charging current for any connected device to ensure the fastest and most efficient charge.


This is nicely designed and comes in a matt black finish.  It’s handy for charging various devices on the go and depending on what you chose to charge can charge items such as phones several times (5-7).

There are 4 LED lights on the unit to show the charging progress of the power bank and when it is not being charged if you press the small button at the side these lights will come on to show you the power level.


There are 5 built in safety mechanism to prevent over charging over-discharging, over-voltage, over-current and short-circuit protection which is great.

What did I think?

I was very pleased to finally have one of these as they are super handy for use when travelling.  I really liked that you can charge more than one item at a time as it’s typical for my phone and my husband’s to run low of battery at the same time so this comes in very useful.  It looks great, I love the sleek and simple finish and the fact that it can hold so much charge.  It is compatible with many smart phone chargers which makes things easy especially if you lose the lead it comes with.  This is a really simple item to use so technophobes do not fear my 2 year old could get things charging if I showed him what to do.

Have you bought a power bank yet?

 I received this product for free in return for an honest and unbiased review

  1. I have been looking for a good power bank too! the one i have is a 400mAh and only charges up my phone once which is not that great! will definitely give this one a try!

  2. I’m sure I have this charger myself, it is actually really good and I love the fact you can charge multiple items at the same time.

  3. If I probably wasn’t always at home and had a busy life and career like I used to before I had T, I might seriously consider this too. I can imagine how handy it is for someone who is always on the go 🙂

  4. Travelling through Europe this summer, having a power bank was really useful. Everything always needed charging at the same time and being able to charge several items at once was a real problem solver. I have a different brand to this one but agree with you about how easy they are to use.

  5. Power banks are great aren’t they? Each of our family members has one and I use mine almost daily – I use. My mobile that much that I’m always running out of battery. Like this one though mine charges devices more than once which is so handy.

  6. That’s super useful, I would certainly use it. Most rooms do not have USB chargers unless they are super modern.

  7. This looks absolutely ideal for me as I go away for long weekends quite a lot and would find using a power bank like this really useful!

  8. I haven’t got one, but they must be really handy to have and the designs now are beautiful; so sleek and tidy-looking. This one looks great!

  9. I am always impressed with Amazons service and they are always so quick to deliver.
    This looks like such a useful bit of kit! 🙂 x

  10. This looks great! I bought one for my brother recently – he’s addicted to Pokemon Go – but I still haven’t got around to buying one for us though.

  11. I have a few different versions of these and they are just so useful. Now I have one I don’t know how I survived without one for so long x

  12. This one looks about 100 times more sleek than the brick I lug around! But I would be lost without mine! I think it’s an essential item in this day and age.

  13. I have one very similar to this but I think I need a more powerful one for when I go away next year as there won’t be as many oppurtunities to charge phones x

  14. Brilliant things for when you’re out the house, especially with how most technology nowa days have rubbish battery life xx

  15. My husbands been looking for a power bank, I’ll have to show him this post, might be something he’d be interested in 🙂

  16. Sounds good that you can charge more than one device at a time. I need power blocks so much when I go to London especially when using my sat nav.

  17. Power banks are so handy! I do have one but I always forget to charge it so it’s pretty useless but it’s only a little one any way, nothing like this!

  18. We recently got a big power bank like this.
    Don’t know what Id do without it honestly. not heard of this brand though – will run it past Mr B and look into it.
    Thanks for sharing hun
