KiWiBiRD 4500mAh Slim Samsung Galaxy S8 Battery Case/Battery Pack Charger/Power Case with 120%+ Extra Battery Power for Galaxy S8 (Not For S8+ Plus) - Matte Black

The case works great, once the phones almost flat I can charge my S8 twice before needing to plug back into the mains. I dont use my phone as much as some people and my normal phone battery would last about a day, so now I've only gotta charge my phone twice a week! The case is pretty bulky and does probably triple the thickness of the over all phone. But for the extra battery life it's worth it. Brought mainly for when on holiday and I'm not going to be able to charge my phone during the day and this case will do the job perfectly.

I like that the casing allows you to keep a screen protector on that wraps round the edge of the screen. I dislike the fact that you have to use the supplied adaptor to use earphones ,but on the whole it's a great little battery pack that allows me to use my phone all day without the need to plug it in to charge it up . The battery indicator is really handy as well, letting you know how much charge is left in the case

Very handy to have, but hugely bulky and weighty. I find myself choosing where or not to use it due to the weight and bulk. It seems disproportionately bulky when compared to the phone itself which has other features other than power store. Very happy with the amount of additional power it provides though.

These are the most practical, best charger cases I have come across for the S8. However they don't seem to last more than 6 months. This is the second one I've had since getting this phone little over a year ago (third if you count the faulty one in between which they replaced immediately.)Old reviews are below.***Upgraded from 1 star***Kiwibird got in contact to arrange a refund and are sending a replacement. Impossible to complain about that. Thank you Kiwibird!Original comment below:Had mine for less than a month, it stopped charging more than half way with the phone plugged in. Tried sending it back but apparently it's impossible to send a faulty battery. Royal Mail won't touch it and all the couriers I've found say it's illegal to do so.Amazon won't refund till they get it back so I'm a bit stuck. Clearly your rights as a consumer don't count for batteries. If you buy a dud you'll just have to take the hit.

I thought the case has a cover for the screen as well but the front cover is open. It'd be better if it had plastic or toughened glass inside it but apart from that it a appears a decent item and fits the phone perfectly without any gaps.

Nicely designed product, great for heavy phone users to re-charge on the go. Took a few days to get used to the weight and thickness, but great product at a great price.

Only reason I feel it should be a 4 for durability and a 3 for ease of use is the blocking of nfc payments and wireless charging but it is stated before I purchased but still you need a perfect product to get perfect score

These are BRILLIANT. my s8 back screen cracked so I've got this to protect it as much as possible. I have one on my old s6 aswell and the battery life is outstanding i cannot reccomend these kiwibird products enough!!! U won't be disappointed honestly
