Store Pickup: Same Day (During Working Hours)
The Baseus Adaman 20000mAh power bank is the one to buy if you want a big battery that will survive being carried around every day. Where most power banks at this price are plastic, the Adaman is built from aluminium alloy – it feels solid, it does not flex, and it does not scuff the way a plastic shell does after a few months in a bag. We stock it at My Memory Store with islandwide delivery across Sri Lanka.
A metal body that lasts
This is the main reason to choose the Baseus Adaman 20000mAh power bank over a cheaper plastic one. The aluminium alloy shell handles being dropped into a backpack with keys and a laptop charger every day. Metal also helps it run cooler under load, which matters when you are pulling 22.5W out of it, and heat is what shortens a battery’s life more than anything else.
22.5W fast charging for almost any phone
The Adaman supports a wide list of fast charge standards – Huawei SCP and FCP, PD3.0, QC4+, QC3.0, PPS and Samsung AFC – so it fast charges Samsung, Xiaomi, Redmi, Huawei, Oppo, Vivo, Realme and iPhone without you needing to check compatibility first. On an iPhone that supports 20W PD, you can expect roughly 60% in about half an hour.
Charge three devices at once
There are two USB-A ports and one USB-C port for output, so your phone, your partner’s phone and a pair of earbuds can all charge together. The USB-C port works both ways – it charges your devices and recharges the power bank. There are three input options in total (USB-C, Micro USB and USB-A), so whatever cable you already own will work.
A digital display that tells you the truth
Instead of four small LED dots that leave you guessing, the Adaman has an LED screen showing the exact remaining percentage along with live voltage and current readings. You know whether you have 62% or 12% left before you leave the house, and you can see at a glance whether a device is actually drawing fast-charge current or trickling.
What 20000mAh actually gives you
This is worth understanding before you buy, because it applies to every power bank on the market, not just this one. The 20000mAh figure is measured at the battery’s own 3.7V. Your phone charges at 5V, and converting between the two loses energy as heat, so the usable output is the rated capacity of 12000mAh printed on the case. In practice that is roughly three to four full charges for a typical 4000-5000mAh phone. Any 20000mAh power bank from any brand behaves the same way – a seller promising five or six full charges is not being straight with you.
Safe to take on a plane
At 74Wh the Adaman sits comfortably under the 100Wh limit airlines set for power banks in hand luggage, so you can take it with you when you travel. As with all power banks, it must go in your carry-on and never in checked baggage.
Adaman or Star-Lord? A quick guide
We stock both at almost the same price, and the difference is simple. The Baseus Star-Lord 20000mAh 22.5W has the same capacity and the same charging speed in a lighter plastic body, and it costs a little less – a good choice if it mostly lives on your desk or bedside table. The Baseus Adaman 20000mAh power bank costs slightly more for the metal shell and the extra input options, and it is the better buy if it goes into a bag with you every day.

Frequently asked questions
How many times will it charge my phone?
The Baseus Adaman 20000mAh power bank gives roughly three to four full charges for a typical 4000-5000mAh phone. The usable figure is the 12000mAh rated capacity, not the 20000mAh cell rating – this is true of every power bank, not just this one.
Can I take it on a plane?
Yes. At 74Wh it is under the 100Wh airline limit. It must travel in your hand luggage, never in checked baggage.
Will it fast charge my phone?
Almost certainly. It supports SCP, FCP, PD3.0, QC4+, QC3.0, PPS and Samsung AFC, which covers Samsung, Xiaomi, Redmi, Huawei, Oppo, Vivo, Realme and iPhone.
How long does it take to recharge?
About 4 to 5.5 hours using an 18W PD adapter through the USB-C port.
