Any powerbank (or any 5 Volt source) will work with any phone. The question is how many charges can you get from a given source? The S5 has a 2800mAh battery, so a 2600mAh power bank will give you less than one full charge. The calculation goes like this:

You never let a lithium battery drop below 40% charge, so you need 1680mAh to recharge the S5's battery. The power bank also shouldn't be discharged to less than 40%, so if you want to charge the phone 4 times you need a power bank with an 11,200mAh capacity. (4 times 1680mAh divided by 60%.)
