You can't charge a surface pro with 5v it need 12v
With a fast search i found this https://www.amazon.com/dp/B01D4HAAL4?psc=1 and this https://www.amazon.com/Lizone%C2%AE-35000mAh-5-Ports-Portable-Microsoft/dp/B015VDLWUM/ref=sr_1_1?ie=UTF8&qid=1478534306&sr=8-1&keywords=surface+pro+battery+bank basically you need a battery bank that can output 12v ( with decent A like 2-2,5 ) and the cable
And here is the SP4 adapter I use. https://www.amazon.com/gp/aw/d/B016ISSNB0/ref=pd_aw_fbt_147_2?ie=UTF8&psc=1&refRID=PFH0868V9KPGJA3Z3DJ9
Edit: It looks like the seller has since changed the item to a car charger. Here is an identical adapter from a different seller.

damn autocorrect from the phone was bad sorry for that. Its that powerbank and https://www.amazon.com/Delippo-Surface-Charging-Microsoft-Charger/dp/B01D4HAAL4/ref=sr_1_25?keywords=surface+DC&qid=1558294396&s=gateway&sr=8-25 cable. If you buy the powerbank use the 12v output since the surface pro 4 (unless you have the M3 chip) isnt made for 20v. I get 2-3 full charges on my Surface Pro 4. It takes about 5-6 hours to charge the powerbank up to full and you get loads of connectors to other computer brands included with the powerbank. Im from sweden so guess the auto correct isnt used to typing English on the cellphone.
