10 monster Pokémon Go battery packs to keep you juiced up

Pokémon Go has quickly become the biggest smash hit mobile game of all time, but it's one that rapidly drains a phone's battery life. Players looking for ways to extend the life of their device during longer Pokémon hunts should choose a portable battery, but which one?

It's all about size; go for something about 3,000mAh or less if you just want a top-up, 6,000mAh for a long day out, or 10,000mAh or over if you want to bullet-proof your battery status.

It's also about connections; most batteries recharge via micro USB, which is annoying if you're an Apple customer, though there are some exceptions. Unless sold in custom 'made for Apple' versions with built-in Apple Lighting cables, almost all battery packs have a USB port to plug in your normal charging lead.

There are traditionally two output levels: 1 amp and 2.1 amp, with the latter great for tablets and faster-charging phones, so have a look at what's on there before purchase. Now, onto the best battery packs to keep you Pokémon Go-ing all day long.

One of the easiest ways to make sure you never run out of juice while on a monster hunt is by wrapping your phone inside a layer of extra battery goodness, in the form of a case.

If doubling the weight of your phone by adding an extra battery isn't your thing, Techlink has come up with something to help out with the Ultrathin.

Just 9mm thick, this example has a built-in Lightning cable, though it's also available with micro USB and it comes with a leather pouch and charging cable. Available in gold/white, silver/white and space gray/black, it's also available in a smaller version rated at 3,000mAh for the iPhone 6S.
