Portable battery for Surface Pro 4?

[Relentless81]

Hi,

Can anyone recommend a portable battery please.

The Anker Pro 2 only puts out 1.5AMPS and the standard charger is 2.5 so I'm concerned it will be very slow so looking at alternatives but its seems unless you're American the options are very limited

Thanks

Anker PowerCore 20100, 2.4amps per port.

I have one and its perfect. I only charge my iPad and phone from it however!
