    So tempting.

      It’s not always about the specs but most importantly what cells these power banks were built with, haven’t owned one of these as yet but would like to find out if anyone knows?

      • Click_It on 20/09/2019 - 09:04

        They use Li-Po flat cells instead of the 18650 cells we're used to in these power bricks. Can't tell you if they're as good or long lasting. I know 18650 cells have the best energy density and owning 2 Xiaomi 20,000's using 18650 cells I know they have great longevity, probably more than my phones which use Li-Po… Should still be pretty good though? Someone more knowledgeable than me could step in.

          I'm not a regular user of power banks - only really while travelling - had a romoss 10000ah battery I got from msy several years ago which still works well but bought several of the ones listed in all sizes recently…handy to leave on the coffee table, etc. So far they are solid, well made and provide a good few charges of phones and other devices. I can't compare to other brands, though these are way better than the old 18650 single cell chargers I had. the 10000mah new model is very compact too so handy for in a jacket pocket, etc.

      You can slowly charge a MacBook but only if it’s switched off. If you try and use the MB whilst charging the battery will continue to drain.

    Woukd this charge a surface book 2?

    • Robc on 20/09/2019 - 01:07

      Itll charge anything. Just at 18w though, so you probably cant have it turned on at the same time.

      • Robc on 20/09/2019 - 06:08

        Kantakahashi below says it wont… very strange.

    • flangeflange on 20/09/2019 - 09:41

      How can this charge a surface? The surface needs the power pack to charge, there is no USB charging option…

      • hypie on 20/09/2019 - 10:37

        That wasn't a referral link… but anyway. As I was saying. it works with the Xiaomi 20,000mAh models with 45w powerbank.

        Go onto google and search USB C to Surface power adapter - It will come up on Amazon. This is the one I use.

        "USB C Type C Power Supply Charger Adapter Charging Cable Cord for Microsoft Surface Pro 6/54/3 150cm "

    • hypie on 20/09/2019 - 10:34

      In my experience with the 20,000mAH model, it could not power or charge the surface. I switched to the Xiaomi model and it works perfectly. This is still a great power bank for emergency use.

  • kendoggs on 20/09/2019 - 00:00

    FYI, can't be used to charge a huawei matebook. Great for phones though

    • Robc on 20/09/2019 - 01:09

      Are you sure? I'd bet it would, if the device is turned off. If you use when it's running, itll extend battery life, but wont charge it. Need a 45w version… not sure many exist in this format.

      • kendoggs on 20/09/2019 - 02:06

        Used it when the battery was low and got bombarded with "your battery is low" notifications which made the laptop unusable.

        Have tested it using the following cables:

        Huawei type-c to type-c (45w): It works for a short moment, then stops charging. (2-3 mins of charging)
        Google pixel type-c to type-c: Same deal as the Huawei cable. (fast charges works wonders for my pixel 2)
        Blitzwolf USB to type-c: The most success so far, it seems to remain on for more than 30 mins.

        Haven't tested it powered down, but get the feeling it'll work as you said.

        • Robc on 20/09/2019 - 06:18

          That's pretty much my experience. I didn't bother trying other cables though. I also found that when my laptop is on, a low power source like this does extend the life. But… as you found it's horrible at 10%, and unless you want to create custom powerplans, the laptop ramps up power usage when plugged in,making the situation even worse.

          Turn it off, plug it in, it'll charge. Find a 45w version, it'll do what you need!

  • bm on 20/09/2019 - 08:44

    Does the 20,000mah battery bank use 18650 cells like the older model here https://www.youtube.com/watch?v=qv9ZRJj0og0

    If they do then it's $3 per 2500mah 18650 cell. Bargain!

    • Robc on 20/09/2019 - 08:49

      Li-po on the 30000…

      • bm on 20/09/2019 - 08:56

        Looks like flat cells on the newer 20,000mah ones too https://www.youtube.com/watch?v=tWDB1iGSDPo

        Still, that's 34c/wh, less than 1/2 the price of hobbyking's cheapest lipo cells. A real bargain if you don't need high drain.

        • Robc on 20/09/2019 - 09:02

          Is it just the cell on this that limits the drain? I get that's the major limiting factor, but I'd imagine the charging output circuit has something to do with it. You'll probably find the cell itself supports a greater draw than the device total.

          • bm on 20/09/2019 - 09:06
            +1

            @Robc: You're completely right - you'd chuck the circuit and get a BMS from ebay and series a few cells for the voltage you need.

            Without any evidence otherwise, for safety's sake, I'd stay below (edited/revised to lower number) 0.5c charge and discharge for these cells. They might be able to handle significantly more but lipo's get grumpy when abused. 0.5c is 5 amps per cell if it's a 20ah 1S2P dual cell pack like in the second video above.

    I got one in the last sale and am very happy with it. Don't use it super often, but have only needed to recharge it once. Be aware that this thing is a monster at 2/3rds the weight of a Macbook though, so just be aware of that. Certainly not a simple, portable solution - but definitely a great backup.

    I bought the Romoss Sense 8+ 30000mAh Power Bank a few weeks ago, happy with the product in general.

    Now, I recognise this is a rare use case but for the few out there… I bought it as a UPS for my Raspberry Pi because of the Passthrough charging.

    Unfortunately when the power fails the Raspberry Pi reboots.
    Not sure why.
    So in my experience, not good as a UPS for Pi.

    • gezza90 on 20/09/2019 - 13:33

      I think that's the case with Xiaomi as well. I tried powering my raspberry pi but it's not active charging. After a few minutes it just shuts off. Even when I charge my Bluetooth headphones (jaybird freedom), it starts charging then cuts off after a few mins. But phone, not a problem stay on charge.

    • macca on 20/09/2019 - 17:07
      +1

      I've found with most of them, even if they support passthrough charging they "blip" the power when it switches from being charged to discharging.

      I ended up using a dumber circuit : https://www.aliexpress.com/item/32969695165.html
      or for a single 18650: https://www.aliexpress.com/item/32841386302.html

      Can confirm these provide continuous power no matter what you do with the input power feed and are a bargain.
