Not a vote for any particular brand really, but some words of wisdom for Samsung Galaxy owners…
Always keep in mind that whatever charger you use it must have at least 2.1A output. I have a couple power packs with 2.0A outputs and the phone will charge for about 10 seconds and then stop (no matter how fully charged the power bank is). The Samsung devices have some kind of circuitry in them which will not accept anything less than 2.1A of charging current. The voltage is same for all power banks, and the MAh is irrelevant in this case (but more is always better).

Might wanna check if it’s not your powerbanks shutting down to protect itself. The phone should charge without problem on waaay less current. If a power bank does not communicate the phone will simply ramp up trying to pull as much as it can handle, this is normal behaviour.Westerdutch said: ↑

Nope, it’s not the power bank. I’ve tried several (different brands, different mAh, etc.), none of them worked. So I went to a high-end computer store and asked, and they confirmed my suspicion. We tried a bunch more and got the same result. The findings; only outputs of 2.1A or higher will charge the Samsung. You can go out on the net and see the same thing…people all moaning about how their power banks won’t charge their Samsung Galaxy(s). Same issue in every description…plug it in for 10 seconds and the charge shuts off. It’s the phone, not the power bank.Edit…BTW, I did eventually find one which works great, and will charge the phone to 100% in about 20 minutes. It’s called an ACCELLORIZE and it’s a 10,000 mAh battery. It’s about the same size and thickness as my phone too. And, on a amusing note, this power supply has two (2) outputs. One is 2.0A and the other is 2.1A. The phone will charge on the 2.1A output, but not on the 2.0A output. Seriously! The 2.0A output will charge everything else I have which will charge via USB, just not the Samsung. It’ll charge my headset, my e-cig, a light I’ve got…just not the phone.
I have a couple of these 10,000 mAh “Poseidon batteries”. So far, loving them. I got the first one from the Kickstarter campaign, and bought a second one a year later. One of them is in my bug out bag.
10,000 mAh of portable power
Waterproof rating of IP-68 (highest possible rating)
Durability rating of MIL-STD-810G (highest possible rating)
Dual-port charging capability (2.4 and 1.0 amps respectively)
Included Micro-USB paracord charging cable, carabiner, and nylon strap
Built-in LED light and lantern with SOS signaling capabilityDCBman said: ↑

This must be the case for the ‘newest’ Samsung products then? I’m still using an S4 phone and haven’t experienced such problems when connecting it to power banks.
I like the look of the S7 but don’t fancy any phone that you can’t easily remove/replace the battery,……sometimes technology takes a step back wards in my opinion,…but it is waterproof so I can see why they have done that.PreparedCitizen said: ↑

That looks like a really nice product, I’m in the UK so the cost of shipping one here makes it a fair bit expensive,….I’ll keep looking for a UK based stockist.DCBman said: ↑

Honestly when i Google the issue i do indeed get a lot of moaning about this but the fun thing of that my phone (galaxy note 3) is one of the devices that being complained about. Mine charges happily at 300mA tho, takes forever but works just fine.Unfortunately no, basically all cheap / noname chinese batteries suck. They don’t have anywhere near the stated capacity. Check this guy’s 18650 test (cells often used in battery chargers like these) and all the cheapo cells don’t even reach 40% their stated capacity.
http://www.ebay.com/gds/18650-Batte…l-from-eBay-below-3-/10000000178020340/g.htmlThe Sony 5000 is one of the best for me but, after 5 years, start to not hold the charge anymore. Use to charge one phone and iPad completely. So the new Anker 5200 is coming together. Both small and weightless. So far so good. SONY around $35,00 and Anker $17.00. So a try for Anker.
My wife and I use several Anker power-core. I use the 20100 MAh Power-core and she carries the 5200MaH
Astro E1. Very good quality product.This begs the question for me: is there a decent casing out there that is ruggedized; allows insertion/removal of a couple of 18650s, has a charging input and two USB outputs? Alternatively I was hoping one of the new generation of flashlights (eg Nitecore MH20) would have a discharge to other equipment capability such as a phone for use as an emergency power charger…

I’ve looked up and down for a similar solution; my opinion is the GoalZero Venture series (sealed (IPX6/IPX68), probably 18650s in there) are your best bet. I understand the need to quickly grab an 18650 out of the pack, but you then negate the entire powerbank functionality. You could use a Nitecore F1 for a single 18650 charger/powerbank solution (throw a couple extra 18650s in a watertight (Pelican 1010?) case).

don’t know about ruggedized, but there is the Thrunite C2. It can hold one 18650, either to charge it or to charge another device.
(I don’t actually own one, so I can’t say if it is any good.)

I have a bigboy bank on the slow boat that (hopefully) does just this minus the ruggerized part;
