Best 20,000 mAh Power Banks (with PD) 2020 Review.
A Power Bank 20000mAh or greater will charge your phone multiple times allowing you to charge mobile devices without having to be tethered to a plug socket
The best way to keep your smartphone running longer or recharge your tablet on the move
Power banks are a must-have. Screens keep getting bigger and processors more powerful, but if there’s one thing that doesn’t seem to improve with today’s mobile devices, it’s the battery’s ability to last the whole day.
And while we’ve seen some superb long-life smartphones recently you can still find you’re running out of charge before you can get near a socket, especially if you’re playing games or streaming video.
Take a power bank with you, though, and you can always get a recharge, even when you’re far from home. In fact, with bigger power banks you can get away for a weekend or go camping and still keep your phone juiced up
The PowerCore 2000 Essential packs a 20,000mAh capacity for a price usually associated with 10,000mAh power banks, and that’s far from the only thing it has going for it.
For one thing, it has dual USB Type-A ports for charging plus both USB Type-C and micro-USB inputs, and while there’s no support for USB-PD, Anker’s PowerIQ and VoltageBoost technologies give you up to 15W of power
Through each Type-A port simultaneously, making this a good pick if you need to charge two phones or a phone and a Switch at the same time.
It also has a trickle-charging mode for Bluetooth headphones and other low-power accessories.
It’s a big and heavy power bank, dwarfing even the biggest phablets and weighing in at 280g. It took the best part of eleven hours to recharge the battery.
PowerAdd’s Slim2 was a great, bulked-up take on the lipstick-sized charger, and now the company has removed the bulk with the EnergyCell 5000.
The new power bank packs the same 5,000mAh capacity into a unit with a smaller 27mm diameter. It’s a centimetre longer than the older version, but at 99g it’s still 21g lighter.
It has the same micro-USB port for charging, and pressing the button on the top will activate the four-segment LED indicator to let you know the current charge level.
Crucially, the EnergyCell 5000 also improves on the old Slim2 when it comes to charging speeds.
It’ll charge at 2.4A and our Xperia X10 Ultra hit 25% in 30 minutes and 52% in an hour, which isn’t bad for such a compact charger.
It doesn’t have the capacity for anything longer than a weekend away, but it’s a brilliant, lightweight backup for when you’re on the move.
You might want a slim and light mobile charger, but does that have to mean doing without useful features?
Not if you buy the Aukey PB-XN10, which packs USB Type-C and Type-A connections into a slimline 195g power bank you could happily slot into a jeans or jacket pocket.
The Type-C port works as both an input and an output, handling a 5V 3A charge in either direction, while the Type-A port delivers 5V 2.4A for faster charging. And if you don’t have a Type-C charger, you can also charge the XN10 over micro-USB.
It’s reasonably speedy, recharging our Xperia X10 Ultra phone to 31% in 30 minutes and 61% in an hour and, while the matte-black case is a bit of a fingerprint magnet, build quality is perfectly robust.
Aukey’s PB-Y36 is pricey for a 10,00mAh power bank, but it has a few features that should make it worth your while.
First, it’s small – roughly the size of a chunky chocolate bar – and doesn’t feel too heavy at 190g. Second, you’ve got a choice of USB-A and USB-C outputs, with the latter being Power Delivery 3 and Quick Charge 3 compatible and doubling up as an input, too.
Combine it with an 18W or higher USB-C charger and you can have it juiced up within three hours. It also does trickle charging for items with small batteries, such as wireless earbuds.
But the best reason to get this power bank is that it’s such a smooth and speedy operator, taking our test phone from zero charge to 69% within an hour.
If you want a compact charger that can get your phone back in action, fast, look no further.
