Model: RP- PB052

 

Please Note: I was given this product in return for a genuine and impartial review.

 

With all gadgets and devices using a variety of USB connections to charge them, it is very handy to have a portable charger as at some point you will run out of power.  Just consider, you are out and about (dare I say in the words?) enjoying the Summer or Winter months and then – Pow!  Your mobile ‘phone runs out of juice (battery power).   You could now miss those very important calls.

 

You wonder, ‘If only I had a portable charger to hand….!’

 

So now is the time to make the desired purchase.

I have had a few portable chargers before this one from Ravpower and although they were adequate and served their intended purpose, they only had one output port and had a limited capacity to charge a ‘phone or device a couple of times.  Enter RavPower.

 

When the parcel arrived, I opened it up and to my surprise, the box that the portable charger was in was quite big.  The box was simple by design and (in my opinion) the colour scheme works well, White, Grey and a touch of Green. Within the box, you get the RAVPower portable charger with a massive (22000mAH) and two Micro USB cables.   Yes, folks, that’s right I said two.   This is a bonus from a preceding model, the RP- PB044.  You also get a nice stylish carry pouch and a user guide and a lifetime warranty card.

 

The design of the unit is simple yet stylish and the colour is a nice dark Black.  It appears well made and has substantial weight (which gives a good feeling that you know the battery is of high quality).  RAVPower uses a high-density Lithium polymer type composition.

1 x RAVPower Ace Series 22000mAh External Battery Pack
2 x Micro-USB Charging Cables – different lengths

The Test

Like the previous model RP- PB044 I have been charging my iPhone 5, with all features running, e.g. Bluetooth, Wireless network connection, Wi-Fi hotspot, push notifications – the list goes on.

 

With a charge capacity of 2.4A, it took just under 3 hours to charge the phone from 5% to 100%. This may appear slow, however, don’t forget the ‘phone was on and in use.  Other battery banks would take longer to charge with all these features enabled.   I managed to get seven full charges while the ‘phone was turned on and in use.

 

With the battery pack fully charged, I was able to charge my iPhone 5 from 5% to 100% on seven occasions.  While this may not sound like a lot, please bear in mind that all the features of the iPhone were turned on and running.  To mention some of the features I always leave on are:  Bluetooth, Wireless network connection, VPN, Email, push notifications, and more.

 

As the ‘phone and all its features were enabled, the phone took again under 3 hours to charge from 5% to 100%.

 

Charging the battery pack from 5% to 100% took around 11 hours.  A great feature to note is there are four bright LEDs which indicate the charge status of your battery pack; each illuminated LED represents approximately 25% charge.   When the unit is charging from 5% to 100%, the first LED will blink.  Once the pack is 25% charged, the first LED will stop blinking, and the remaining three LEDs continue to blink.  When the pack becomes 50% charged the second LED stops blinking and the remaining 2 LEDs carry on blinking and so forth until fully charged.  When the battery pack is fully charged, all LEDs automatically switch off.

 

I received this product back on 29.08.2016 and to date (02/12/2018) putting this review up on our site, I have to say it’s still going strong and has not lost its power output and does not take any longer to charge up too.

 

For me, there are only a couple of minus points (tempered by plenty of pros).  The weight of the battery pack is quite heavy and it is not IP66 rated (dust and waterproof).

 

Perhaps the minus points that I raised are a little bit harsh as any pack that is good, especially with rechargeable batteries, will be heavy if they are using high-quality batteries.   Until better technology is developed in the battery industry, this is the prospect we’ll have to accept.  Also, the pack is not IP66 rated (as of 2016).  I should point out that the competitors don’t have IP66 rated external battery packs either although it could be an idea for future models.  It is something I would have liked to have seen.

 

 

Conclusion:
If you’re after an external battery pack with a lot of power then this unit is for you.   I am delighted with the product and have recommended it to my family and friends.  It is well worth the money.
