    kris1234's avatar
    works for me (edited)

    10,000mah but due to wireless charging inefficiencies and the heat it generates it manages to charge in best case to about 40% and worst case about 27%. Returned. If you want this kind of thing get the apple one. (edited)
    Mentos's avatar
    I suspect even the Apple one will suffer from loss. If you’re going to lug a power bank around, probably best to get the most of it and go wired IMO.

    well charged my iPhone from 3% to 100% and still 2 led lighting of 4

    This will wreck the phone. Avoid.
    jujuzeez's avatar
    oh with the added USB C port too? :/
  5. bogdan_lm20's avatar
    Hi, can this be used with the case on or do I need to remove it every time I want to charge the phone ?
    Imax242629's avatar
    I think you need a MagSafe case
  6. Find_Out's avatar
    Is it only for iPhone?
    jujuzeez's avatar
    u can use it for any phone so far you attach a magsafe case (magnetic case). it also allows usb-c charging (usb-c port)

    Is this any good

    "I had this power bank from Amazon. It didn’t recharge after the first use. Many comments on Amazon state the same issue."

    According to another commenter here.

    Has anyone else been told that the UK Warehouse has no more stock and they have to wait for a dispatch from the international warehouse?
    jujuzeez's avatar
    not got the email yet. could come later for me. anyways I can wait. I don't even have a magsafe supported device atm. only ordered magsafe cases (for my #GalaxyS23Ultra) off AliExpress yesterday before placing an order for this.
  10. coolboy101's avatar
    Just an FYI for people thinking of buying one of these, they don't charge unless the battery pack detects that the temperature is above 20 degrees Celsius. This is most likely the reason lots of people on Amazon say that it would never charge, and I only found this out after thinking my first one was faulty and being sent another one that also wouldn't charge. After lots of back and forth with ESR they mentioned the 20 degree limit, which isn't mentioned anywhere on the product page or information on the box/manual. I put both of mine in front of a heater for a minute or two to raise their temperature a bit, plugged them in, and they both started charging as expected.

    It seems that they set the minimum charging temperature too low, ESR probably didn't calibrate it for temperature in UK households, especially during winter which is when I bought mine!

    thanks for this bit of information

    Anybody received it yet ?

  12. mxer450's avatar
    Yep got mine today too, lol.

    Excellent product although I did get a warning message from apple iPhone 12 saying it stopped the wireless charging due to excessive temperatures??? Never seen this before but never wireless charged before either. So 🤷
    jujuzeez's avatar
    I've experienced that with my old iPhone XS. happens once in a while not all the time. depends on room temperature and the condition of the phone at the point in time. I only used mine for like 5 mins today (with #S23Ultra) when I got it. so I didn't experience anything of such cos my battery was 🔋
  13. medicgaming123's avatar
    Don’t get the appeal for mag safe battery packs. Perhaps it’s the convenience of not having cables, but even then it’s a 5W charger. Would take an hour just to get 20% or so. I bought the Anker Mag Go version with a 18.8 wH capacity, which was less than half the price of Apple’s, has 50% greater capacity (Apple’s is less than 14 wH), and I still end up resorting to using a cable.
    OhTheMajesty's avatar
    They’re for using on the go. And for their intended purpose, they’re perfect
  14. OhTheMajesty's avatar
    I use the Anker 622 with the flap stand and it’s great…albeit more expensive
  15. jujuzeez's avatar
  16. uthypranks_TV's avatar
    great deal. i have a normal power bank but bringing cables makes it sm less portable.
  17. psel13's avatar
    I nearly bought the Anker equivalent the other day for double this price, bargain thanks op
    psel13's avatar
    And £2.57 TopCashback pending too
  18. NorthOsiris's avatar
    Code works with the smaller halo lock too.

    I have a 13 mini so for £16.20 delivered this is pretty decent.

    cheers OP!

    Looking at Amazon now ...

    265 global ratings - 70% 5 Star - 10% 1 Star

    Maybe you are looking at a different Amazon ?

    Very Good price for 10000mah
    Normally, 6000mah comes around least £25
    At least this will charge your phone to full.
    Better than 6000mah which just tops up the battery a little bit. (edited)
  26. mxer450's avatar
    Thanks op, perfect timing
  27. Voyto's avatar
    Ordered the 5000mah for £16.20 using your code. Thanks
    itsluke's avatar
    For only a few quid more you get double the capacity. Why?
  28. jujuzeez's avatar
    thanks op. bought. taking a gamble on the product efficiency and durability. the offer is hard to passover. anker prices for such products are exorbitant
  29. the.porter's avatar
    Ordered thanks op and I bet you all forgot tcb 12.6% cb
    jujuzeez's avatar
    yes I applied it, TCP is unreliable though. might not track.

    In layman terms how much 10k mah charge iPhones or iPad?

  32. EndemicAlarm's avatar
    Ugh, why must I be a slowpoke. Somebody ping me if this comes back into stock...
    Voyto's avatar
    the 5000mah version is still available @ £16.20
  33. tlhdz's avatar
    I keep getting the error "Coupon limit has been reached" when trying to add the code to the 5000mah version
