    Romoss, I have a couple that perform perfectly. Allows for fast charging, robust and reliable.

    Skip the cheap and nasty powerbanks.

    I had a Romoss.
    It worked well until it one day swelled up, lost it's smoke and died.
    It could charge and discharge at the same time - the cheapy replacement could not, which is a negative.
    The cheapy did not last long.

    I coughed up and bought an original Samsung. Worth the money. A word of caution, not all cables care made equal.

    Romoss 30000, amazing capacity but see it’s buldging after about ~4 years so time for replacement.

    Best power bank I ever had was a Red-E, they are very expensive though, still worked well after 5 years, then got stolen with a laptop.
    I currently have a Romoss 20000ma I think, I don't use it a lot since I mostly plug my phone in to my laptop when I need to charge on the move.

    What cellphone and how many charges your need?

    You can get things that csn just top up 30% for emergency, Charge once, charge 4x times or charge you phone a DNA laptop for 2 days. Depending on what your are charging.

    I only know Romoss and recommend them after trying a few brands over the years.

    I had a Romoss 2600 mAh. It worked but the stress I put on it, it didnt last. Its a bit small for todays stuff. The current average phone batter is like 4000* mAh. fixed
    A Romoss 5000mAh will keep your phone and trigger cam charged once, maybe. I keep it in my day bag just in case.
    If you want to go bigger, a Romoss 30 000mAh Sense 8+ (There are different versions, you want the plus quick charge, if you are carrying this monstrosity) Will probably charge your stuff about 4x times
    And then if you have the bakkie with you, a : Romoss 60000mAh (222Wh) Basically charges your phone and cam for a few weeks. It is a brick though.

    Romoss is the brand to go for. My 30000Mah has been going since 2020. It still works and does duty at home during loadshedding.

    I then bought a 60000Mah that i take with me everywhere and that is still as good as new. Can get around 12 full charges out of it. But its a bit to big to carry around with you especially if you don't have a backpack or laptop bag to put it in.

    You get the fast charging versions of both and a good cable is equally as important.

    Id go for the 30000Mah again if the 60000Mah dies someday.

    The 60000Mah also takes about 18 hours to fully charge on a fast charger

    My wife borrowed my Romoss 30000 on a trip to america and always got stopped at security. Her phone never went flat though but she compained it weighed a lot in her handbag, alrhough I'd like to argue there is a lot of unnecessry stuff weighing a lot more in a womans handbag. But I believe in those. Charge them once, use them long time. Just be warned flying with the 30000 might be a slight hassle.

    Had mine taken away while traveling through Beijings Airport. I had a smallish 10 000 mAh power bank, which at absolute most , if its a 5 volt pack (most are 3,7v), equates to 50 watt hours.
    The limit according to IATA's table 2,3A (see pic) is 160WH.

    The reason it was taken away? It's only specified in mAh's not WH's.

    It's a simple conversion. Wh = mAh x V / 1000

    No amount of attempted reasoning worked. Even with the stripes on the shoulders.
    The pile of confiscated power banks was ever growing.
    I would have to buy another.
    Where are most power banks made? China.

    So if you want to travel with a power bank (in China at least), make sure its specified in WH. If not, leave it at home or print a sticker after doing the the conversion. Oh and Don't put it in your checked-in luggage. Trust me, you can't afford it if they make you pay for the cost of a diversion should it catch fire in the hold.
    Oh, And you also don't really want to be on board an aeroplane with a lithium fire burning.

    I use Romoss, Anker and Red-E, never had a problem.

    Size will depend on your intended use.

    As mentioned, the cable makes a big difference. a Good but short cable gives the best transfer.

    Also keep in mind that it will not output the full capacity, only about 70 - 90% depending on the quality of the power bank.

    I've purchased 3 x Red-E's in my life .... 2 x 20 000 and 1 x 10 000 - the 2 bigger one's ballooned after roughly 2 years of use, the smaller one still works fine, granted it is used maybe once a month, if that much.
