Some three years ago I took a tour to the far-reaches of the Mobile World Congress. Back in Hall 8 we stumbled across something called “graphene” and didn’t really know a great deal about it. Now, though, we have a high-quality portable charger with a graphene composite battery …

You remember these guys, right? They sell conversion kits to turn your “normal” bike into an e-bike. We covered all this back in June, including how it all fits together. Now they’ve got a new 2-speed motor, so you can knock it into a lower “gear” effectively to …

The smartphone world has slightly backed away from chunky long-life batteries and has, in some cases, gone for a super-slim battery that can be charged wirelessly in no time at all. Today OPPO have really raised the bar. They’ve announced a stack of new flash chargers, and at …

My son recently got through his twelfth iPhone cable. It has, if nothing else, taught me to buy quality cables and not those ultra-cheap eBay ones that only cost £2 but last about 2 minutes. If you’re looking for reliable products that support your lifestyle, try getting your …

It only seems like 5 minutes since we took a look at the Realme 5 Pro (which is available for a mere £209 on the UK Realme site) but wait, there’s a Realme 6 Pro around the corner and we’ll be seeing it for real this coming Tuesday. …

As you’ll have no doubt seen here at Coolsmartphone, there’s a definite increase in powerful gaming phones of late. They’re brilliant. There’s enhanced graphics capabilities, a number of faster processors and bigger, faster-charging batteries. However, if you’re trying to play a game on your phone which is both graphic and …

Want your battery charging? Let’s face it, there’s far too many people who rely on a charger or portable power pack being close to hand. The people at OnePlus are seeking to change all that, with their WarpChargeSOS fire truck taking to the streets of London to top …

This was never meant to be a battery test. What happened, if I’m honest, is that I forgot to charge the ZenFone 6 one night. This meant that I had to go into uncharted territory. A second day on battery. So that happened, and the 5000mAh battery simply …

Last weekend I went camping and, without doubt, the portable charger was definitely a key piece of kit. However, remembering to bring one of these with you is a challenge, so this – the TravelCard – can sit in your wallet or purse ready for you to use …

Which? tested nine iPhone models and found that all of …

Laptop manufacture HP has issued a further recall of laptop batteries. This comes after the company recalled 50,000 batteries, and that came in the wake of a 101,000 battery recall during the previous year. This time it’s because of concerns over “fire and burn hazards.” The company had …

I mentioned how good the Honor View20 battery life was in my recent review but, as some of you may have seen on Twitter last night, I’m constantly surprised by just how long it does last. It’s like the Energizer bunny. In years past, Huawei / Honor were …

I’ve performed a couple of tests today with the Honor 8X. The first is to check Strava. It’s an app I use a lot to track my exercise and, as you might know, I’ve had some issues with it working properly on Honor / Huawei kit. From what …

This one hasn’t even gone fully live on Indigogo as yet but, from what I can see, this is a case, an extra battery for your iPhone and a walkie-talkie, all in one. Cheap data, better coverage and apps like WhatsApp, which has an inbuilt audio recording / …

A normal portable phone charger, right? Wrong! This is the Novoo power bank and it’s got a whopping 20,100mAh capacity. That means it’ll fully recharge a smartphone (assuming 3000mAh battery), from flat, nearly 7 times. Great for a week away. It has a USB output and a USB-C …

We have all now accepted the unrivaled role of smartphones in our lives. There is rarely a moment they are not accompanying us through the various different activities of our day; at work, during our commute, out with friends and even at the gym. Giving us direct access …

Recently, I was sent the Moshi IonBank 5K Portable battery unit for testing, which retails at £100.00 (yes, this is not a typo) for the 5150 mAh unit. There is the cheaper 3K unit at £69.95 and 10k which costs £89.95. The 5K unit looks like a metal business …

OK, so you’re probably going to have to watch the numerous potholes that are about at the moment. Riding one of these things on a road could  be eventful for all the wrong reasons if you don’t have your wits about you. I’ve reported a cluster of around 6 …

Perhaps the biggest complaint about all smartphones is the battery life. I, like many of your probably, end up charging the phone every single day. However, a new phone from Energizer (the battery people) comes equipped with a 4,500 mAh battery. They tell me that it’ll cope with …

Another day, another power bank. This is available from Amazon UK for a mere £12 with free UK delivery. Not a bad price that at all. It’s about 1cm taller than a credit card and a tad wider. Inside thee’s a 5,000mAh battery which will charge the 3,000 …

Following some rather technical research and testing from Geekbench, Apple have finally admitted that they do indeed slow down iPhones. It’s long been a suspicion of iPhone owners, who tend to feel that their handset slows just before the launch of the next Apple phone. Now though, we …

We’ve received an email from NOA. They’re about to launch their first smartphone with an 18:9 screen ratio and DTS audio. It’s called the NOA N8 and has a near 6″ screen, though it’s 720x1440px. It also has a 5000 mAh battery, which seems very decent, and that …

Nokia, currently owned by HMD Global, is trying to make the next breed of handsets relive the glory days of strong battery life. This is something that has not been possible with the current era of smartphones. The new Nokia 2, which is due for release in the UK …

Yesterday we reviewed the 10,000mAh portable charger from RAVPower. It’s small enough to fit in your pocket and is powerful enough to recharge your smartphone or Bluetooth speaker several times over. It’s only £13.99 from Amazon but we’ve managed to get it down even further with an exclusive …

WOoo!!! Another power bank for me to review. I LIVE TO REVIEW POWER BANKS!!! Guess what this one does. Go on, guess! Yes, this will power up from a wall charger or another USB input via the microUSB central “Input port”. You get two microUSB-to-USB cables in the …

The lovely people at ROMOSS were so happy with our earlier review of their all-in-one power bank that they’ve sent us ale and a free man shed. Not only that, but there’s also an exclusive 20% voucher code if you want to buy one from Amazon. The portable …

Last week I was reviewing a car and this week I’m getting a pitch from an electric scooter company. It’s certainly different to my years of reviewing phones. This one is an electric bike which can get you to nearly 28 mph in just 3.3 seconds. Depending how …

Portable chargers. Yes, there’s lots of them on the market. This one is from ROMOSS and they’ve designed it so that it’s got plenty of capacity whilst still fitting in your trouser pocket. That’s a good thing. There’s 2 output ports and a 10,000mAh capacity. You can charge …

Despite clever power-saving features in smartphones, there’s still one fairly standard rule when it comes to a battery. If you want it to last for ages, you’ll need a higher capacity. A higher capacity usually means a fatter, bigger, heavier battery.. and people don’t like that. So people …

At just 8.5mm, this is as thin as some smartphones. It sits in your pocket and is easy to carry around in your jeans without any unsightly bulges, measuring in at just 13 x 7 x 0.85 cm. Inside the aluminium casing there’s a 5,150mAh battery and it’ll …

We all need convenience in our lives. After all, this is one of the reasons that we use mobile phones as much as we do. However, it’s a real pain when the piece of tech that we rely on so much falls flat on its shiny face due …

Using a battery powered device on a flight? It’s not just phones you need to be concerned with. In Australia authorities are now issuing warnings for powered headphones​. It comes after a passenger on a Beijing to Melbourne flight suffered burns and blisters as her headphones exploded mid-flight. …

Usual introduction to this. You know the story. Smartphone batteries aren’t great. We don’t want fat batteries, but at the same time we don’t want to be running back to a power point to juice the thing up every few minutes. So what are you going to do? …

Somehow, for some odd reason, I appear to have gained a reputation for reviewing random electronic gadgets. Today I present to you …..a torch. Call is the flashlight, call it a torch, it is simply a small battery-powered LED light which you can carry around on your keys. …
