External Battery for Pro 4

[Acudoc]

Been loving my Surface Pro 4 but battery life is pretty poor. Because of this, I need an external battery/cable for an upcoming long trip. Any ideas or experience with this?

Thanks so much.

Is it compatible with the surface pro 3/4?
Answer: [Yes it should. The barrel connector of your adapter cord (5+ mm O.D.) plugs right into the RAV.]
AMENDED answer (6-20-2015):
The Surface Pro 3/4 charging tip is proprietary, and specific to connecting to the SP3/4. To use the RAV, you'll need a specialized cable, with that tip on one end, and a barrel connector on the other, which needs to be 5.5x2.5 mm. Most of the available charger cables seem to have only the 5.5x2.1 barrel connector, so you'll also need an adapter for that--namely a female 5.5x2.1 to male 5.5x2.5 adapter, to plug into the RAV output which requires the 5.5x2.5 mm dimension. Here are a few product links from Amazon--(read the comments, as there is a wide variation in the successes). Maybe order a cable from two sources.

I checked the Microsoft website for a comparable OEM cable, but found none.
Hope this clarifies, and helps.

This helps a lot. Do you know if the Surface Pro 4 can be used while be charged by the RAV?

Got this one yesterday after seeing it referenced in the "battery life thread".

Amazon.com: Qi-Infinity? Powergrid 34200mAh External Battery Pack/High Capacity Power Bank charger for Laptops, Notebooks, Netbooks, Tablets and Smart Phones: Cell Phones & Accessories

It's certainly powerful enough and supports a wide range of products, voltages, and interfaces. It recharged my SP4 from 10% to fully charged while draining itself from 100% down to about 55%. So theoretically it could fully charge it twice?

Only complaint I have read is more than one buyer stated the led went out. That led is important since it indicates your settings and state of charge.

Regardless, with these new fangled external batteries, we can be less concerned about the shorter battery life of these new modern mobile powerhouses and their extreme svelteness. Good luck.

Did you need to buy a special cable to connect the Qi-Infinity to your Surface Pro?

 

[snakebitten]

Yes. And that link should have suggested the SP3\4 cable as a piggyback purchase. ?

Note, it comes with a cable for the Surface Pro 2 and just about any laptop. Everything except the one we need.

You can use the power cover from the surface pro 1

See this thread on Reddit: https://www.reddit.com/r/Surface/comments/3tyea6/powerbank_for_the_sp4/.

There's a new Qi-Infinity 35,000 mAh battery coming out which looks to be a good improvement over the 34,200 mAh model. It is 26% lighter and also smaller. They say it will be available Dec 5. It will come with a SP4 cable in the box.

Has anyone used the power cover? I saw in a youtube video that the power covers from the previous versions don't work with Surface Pro 4.

Love this device but the battery life is atrocious.

I use the power cover for the SP1 on my sp3 and it works great! You need to do a Windows update thou.
