Trontium’s colossal battery pack has enough juice to charge your iPhone 50 times

Extended battery cases for smartphones are handy, and some of the more powerful ones can recharge your phone several times over. Separate battery packs are sometimes even stronger, potentially keeping the battery topped up for days. But what if that’s not enough? Then you’ll want the Trontium Reactor.

Apart from having one of the coolest product names we’ve heard in a while, the Reactor is the world’s first completely universal battery, with the highest energy and power density of any consumer battery yet. The company says it’s “like nothing ever created,” and we’d be inclined to agree. Amazingly, it has enough juice inside to recharge your iPhone 5S fifty times over. It uses a new technology called USB Power Delivery, which boosts the modest charging capabilities of a USB 3.0 cable to 100 watts and up to 20 volts.

Trontium Reactor woodsThe Reactor has a monster 290 watt-hour battery inside, and three 100 watt-capable USB ports on the top. It doesn’t only charge phones either, it’ll sort out your Nexus 7 sixteen times over, your 13-inch Macbook Air 5 times, or a Surface Pro 2 6 times. With the addition of a special splitter cable, the Reactor can recharge up to 18 phones at the same time from a single USB port.

The Reactor looks like a massive AA battery, in that it’s a big cylinder, but with a multi-colored LED light ring for showing charge levels and rates. To alter the settings there is a small touch sensor fitted to the Reactor, but most adjustments will be made using the special Bluetooth connected smartphone app. Custom profiles can be created from the app, letting you set the Reactor up to power hardware which doesn’t support USB Power Delivery. If you’re wondering how to charge the Reactor itself, it can be done using a car battery, when it takes 5 hours. As this would prove inconvenient for many people, an Apple 12w USB adaptor will also do the job, but in sloth-like thirty hours.

Made from anodized aluminum, unsurprisingly, the Reactor is a bit of a beast. It’s 9-inches long, nearly 3-inches wide, and weighs 1.4kg. It’s also quite expensive at $300, but when you think a regular extended battery pack or smartphone case can cost anywhere up to $100, it’s good value considering the return.

Of course, the Reactor will be overkill for most people. However, its enormous power reserves and relatively compact size make it the perfect companion for keen hikers, those on expeditions, or even travelers going off the beaten track, who don’t want to carry chargers and adaptors everywhere. Additionally, it’ll be invaluable in developing countries, where power can be unstable, or difficult to find.

The Trontium Reactor is up for pre-order now, with delivery expected to take place in September. It’s a crowd-funding type deal too, so you’ll be charged straight away, and the funds are being used to finance the device’s final stage of development.

This one trick will charge your iPhone’s battery faster
trick charge iphone battery faster charging

We've all been there -- you're about to leave the house and your phone is seriously running out of battery. You'll probably just plug your phone in and get as much juice as you possibly can in a small amount of time. Fast charging makes that a simple task, if your phone's battery is really low — but when your iPhone already has a decent charge, you'll find it charges pretty slowly no matter what you plug it into.
There's a way, however, to get your iPhone to 100% that extra bit faster — and it's hidden in your Settings app.

To charge your phone to 100% quicker, open up the Settings app, head to the Battery Health section, then toggle off the Optimized Battery Charging switch. That seems counterintuitive, but it really works — here's why.
Best fast chargers for iPhone and Android
Turns out, it's actually not all that healthy for your phone's battery to continuously charge straight to 100%, and sit at 100%, all of the time. According to Apple, batteries can age more or less depending on factors like charging patterns and temperature -- and the more they age, the less charge they can actually hold. Leaving your phone at 100% on a charger for hours and hours on end accelerates that degradation. In other words, the real-world effects of quickly charging your battery and leaving it at 100% over and over again are actually tangible. Even if that impact won't be felt for a year or two into the phone's life.
Use this feature sparingly — but when you need it, it's wonderful to have the option.

This tiny charger will take your iPhone from 0% to 50% in only 30 minutes
Anker PowerPort III Nano Wall Charger

Almost everyone today carries at least one wireless device in their pocket, but the flip-side of wireless freedom is that those internal batteries need daily charging -- yet many standard wall chargers and portable power banks simply don't juice up your gadgets quickly enough when you're on the move. Enter the super-cheap Anker PowerPort III Nano, a pocket-friendly wall charger that can take your iPhone and other devices from 0% to 50% in as little as 30 minutes -- and it's on sale right now for just $12.

You probably remember the wailing and gnashing of teeth that took place when 3.5mm headphone jacks started disappearing from new smartphones, but fast-forward a few years and it now seems like most of us can't leave the house without at least carrying our favorite pair of wireless earbuds. It's not hard to see why people relish in being freed from the tangled tyranny of cables, but not everyone appreciates how advances in battery technology have made that wireless revolution possible in the first place.
