Was looking for a cheapish power bank with wireless charging after I inadvertently and stupidly destroyed my old Blitzwolf BW-P10 and came across this one for what seems to be its new regular sale price according the camels (though via voucher this time)

So far seems to be working well, and supports passthrough charging (although at a slower rate than normal). Not a lightweight carry though, weighing in at around 380g. Has a large LED display indicating battery % and charge function (fast etc) which is unfortunately on top so you can't see it when wireless charging unless you place your phone at 90 degrees). Includes a carry bag also.

The title and specs seem a little all over the place though, despite the product page title saying PD 22.5W and QC 18W the output specs and description indicate PD 20W and QC 22.5W.

Model: C2023W
Capacity: 20000mAh, 74Wh

Input:
Micro USB: 5V-2A, 9V-2A, 12V-1.5A
USB-C: 5V-2.6A, 9V-2A, 12V-1.5A

Output:
USB-C (PD): 5-6V-3A, 6-9V-2.22A, 9-12V-1.67A
USB 1/2: 5V-2.4A
USB 3 (QC): 4.5V-5A, 5V-4.5A, 9V-2A,12V-1.5A
Wireless: 5W, 7.5W, 10W, 15W

(and if you're wondering what I did to my BW-P10, while testing the wireless charging with my moto, although fully charged the wireless charging kept stopping and starting every couple of seconds. While charging the powerbank it worked ok though, and during testing I managed to unplug my USB-C cable then while not looking plug it back in to the USB-A QC port instead. Shorted it, and powerbank would light up when turned on but no charge in, no charge out.. to make it worse, I could feel the chipset heating up so I had to rip it open to disconnect the battery.)

    How many times can it charge an iphone from 0-100 on one change?

    • bamzero on 31/01/2025 - 19:03

      Well I don't know which iPhone or what size battery it has but Charmast claim "iPhone 12 Pro Max 3.6 times, iPhone 12 Pro/12 4.8 times, Samsung S21 3.4 times, OPPO Reno4 3.3 times etc."

    • sharky_k on 31/01/2025 - 19:04

      Depends of which iphone. Probably about 4 times.
      Edit: beaten (by a much better response :P)

  • fishandchips on 31/01/2025 - 19:05

    Ordered. Thanks

  • Aminn on 31/01/2025 - 19:10

    Ordered one, tnx

  • Guybrush57 on 31/01/2025 - 19:28

    How on earth do I get the code to work?

    EDIT: Got it. Needed to refresh the page to show the discounted price after redemption.

    • bamzero on 31/01/2025 - 19:29

      Just click redeem on the product page and it should apply at checkout.

      • Guybrush57 on 31/01/2025 - 19:31

        I clicked redeem but the first time it didn't show the correct price. I thought it had expired or I'd screwed up. Got it in the end though. Pretty good price for 20000mAh. Thanks for the deal bamzero!

  • sn809 on 31/01/2025 - 19:49

    Has it expired?

    • MrMiser on 31/01/2025 - 19:51

      Yeah, I'm thinking it has… I'm not seeing any 'redeem' option :(

    • bamzero on 31/01/2025 - 19:55

      Bugger, seems so. Set a camel watch, past history shows it shouldn't be too long before it's back at this price.

    • bamzero on 01/02/2025 - 11:44

      New code available now

  • beesquared on 31/01/2025 - 19:54

    Not seeing a redeem coupon option, might just be blind though!

    • beesquared on 31/01/2025 - 19:54

      Ok, now marked expired

      It's back with a new code

      • umyeahokay on 01/02/2025 - 14:16

        Where's the code?

          Missed it again

  • nepalesesquirrel on 31/01/2025 - 20:30

    Been looking for one for a while and snapped this deal up couple of days ago, it arrived today and it works well. It is a lot ligther and smaller than my Romos 20000mAh.

    • bamzero on 01/02/2025 - 02:53

      Yeh got mine yesterday but only got around to trying it today. Mainly been using for wireless charging but happy with it so far.
      I've had Charmast's 23800mAh (looks the same without the wireless) for a while and hasn't given me any drama so far.

      • Rsalim on 03/02/2025 - 21:38

        Does it have magnet to attach to magsafe?

    Weirdly, got the voucher in the browser but not in the app. Got one for the discounted price just now so not fully expired? Give it a try.

    • bamzero on 01/02/2025 - 11:43

      Yep, seeing a new promo code here (in browser and app). Thanks for the heads up, I'll unexpire it.

    Same here I just got the discount via the app and ordered one. Cheers OP

  • Jayd3n on 01/02/2025 - 12:02

    Showing $61.32 for me with 40% discount redeemed already? Am I missing something?

    • bamzero on 01/02/2025 - 12:03

      Should see final price at checkout (promotional credit of $24.53 applied)

  • Jayd3n on 01/02/2025 - 12:05

    Yaah my bad. Overlooked it. Thanks ordered one!

  • jiancoek on 01/02/2025 - 12:24

    Is promo expired ?

    • bamzero on 01/02/2025 - 13:21

      I was still seeing it until about 5 mins ago, went to get a screenshot and seems it's gone again. All I can say is check back again later as it may return a 3rd time.

  • mirridon on 01/02/2025 - 12:39

    Own it, love it. Never use the wireless charging component though.

  • eatwell365 on 01/02/2025 - 13:33

    Just bought one. It is not expired yet. Click on options

  • omgilia on 01/02/2025 - 14:17

    Damn im only see 40% for the slim model and not for the one posted here :(

    40% off for this haven't expired https://www.amazon.com.au/dp/B08B4M2DNC

      • bamzero on 02/02/2025 - 12:04

    How does the brand compare to INIU or Anker?

  • Chinerama on 03/02/2025 - 14:48

    I added items to make total purchase over $59 for free delivery… But still being charged delivery. I might be missing something if anyone can help enlighten me. Thanks heaps.

    • bamzero on 03/02/2025 - 17:48

      Maybe it's something specific to your delivery address. Since the original price is already over $59 it should be free delivery even after promotional discount.

      • Chinerama on 03/02/2025 - 22:44

        Yeah, it's just weird. It's only a suburb in Melbourne Metro so nothing out of the ordinary…
