Review – Tronsmart PB20 20,000mAh power bank
Power banks. It used to be an essential accessory for everyone. Today, power banks are still useful for many use cases – especially these power banks can output high power. This Tronsmart PB20 is a 20,000mAh power bank that comes with an interesting twist.
I dub the Tronsmart PB20 the best power bank for this transitional period – and here’s why.
Unboxing
It’s a pretty simple packaging. There are a few feature highlights at the front and that’s it.
At the back, we can see more details regarding its selection of ports and its respective voltage/current for each port.
Opening up the box reveals the basic accessories that come with power banks. We have a pretty short, flat micro USB cable.
Design
Remember when we posted this? We raged on the multiple different USB cables that we need to have so that we can charge our gadgets.
But then comes the Tronsmart PB20. This power bank comes with a total of 3 ports, and here are its functions:
- USB-A: For output only, 5V/3A max
- Micro USB: For input only, 5V/2A max
- USB-C: For both input and output. 5V/3A max
And that USB-C port is the most important here. This power bank covers both generations of devices – older devices that are using micro USB and also newer devices that use USB-C. This is going to be the most inclusive power bank that I’ve used – ever.
One thing to take note is that the USB-C port is at the side. Honestly, I don’t like where it is located. So, I need to buy a right-angled USB-C to USB-C cable so the cable doesn’t protrude at an awkward angle.
The power bank itself is not exactly the smallest since it is packing up 20,000mAh capacity anyway. There is also a display to show the battery capacity in percentage. For me personally, I prefer some LEDs to indicate the battery instead of this 7-segment display. There’s also a button on the side to check the battery level.
The textures on the Tronsmart PB20 is a rather weird one. On the top, it’s made out of this soft-touch material, but at the bottom, it has a texture that feels like a piece of fabric with low thread count. Not a big deal though.
Charging performance
Alright, let’s get down to the charging speed. The Tronsmart PB20 can output a maximum of 5V 3A, which tops off at 15W. However, this is not compliant with Qualcomm’s QuickCharge 3.0 or later.
So, in our test, we used the Xiaomi Mi 9 (review) and a total of 3 different chargers – the Tronsmart PB20, the Qualcomm QuickCharge 3.0 stock charger, and also a standard 5V 2A charger that we use for all charger tests that we use.
The result is quite unexpected. This is where we can tangibly proof that there are multiple ways to achieve the same wattage. Balancing between voltage and current important – and higher wattage doesn’t necessarily mean it’s the fastest. Still, it is faster than the standard 5V 2A.
For those who want to charge the Nintendo Switch (like me), then the Tronsmart PB20 is suitable as well. With 5V 3A, the Switch can be charged slowly while playing – which is good enough.
Wrapping up the Tronsmart PB20
Overall, I think the Tronsmart PB20 is still a great power bank. Packed with 20,000mAh in capacity and can output 5V 3A but it doesn’t provide the fastest charging speed since it is not in compliant with Qualcomm’s QuickCharge standards. However, you can charge the Nintendo Switch pretty well in handheld mode.
Also, I still say that the Tronsmart PB20 is the best power bank for this transitional period to go full USB-C. It can be charged with both USB-C and micro USB, so yeah – it’s perfect.
The price though, it’s RM159. It’s quite good for the capacity and the capacity of it – and most importantly, the selection of ports.

The Three Best USB Power Banks You Can Buy
You use your phone a lot. It runs out of battery. You cry. Solve that.
I’ve spent a lot of time testing a lot of USB power banks, USB batteries, portable USB chargers or whatever you want to call them. I use a lot of gadgets, and I use a lot of power, and I have an obsessive need to keep everything topped up to a 100 per cent charge. Over my years of testing, these are my absolute favourite portable USB power banks.
I know it’s a weird thing to have a favourite of, but it’s like a good pair of shoes. A good power bank is reliable, does exactly what you need, and doesn’t get in the way. And that means no funky shapes, no flimsy designs — just a box full of batteries that works every time you need it to.
I don’t mean for this to be the be all and end all of USB battery hot takes, though. I’m pretty confident of my top picks, but do you disagree? Is there a better one out there that you’ve used? If you’ve got any other suggestions, feel free to drop them into the Комментарии и мнения владельцев!
Cygnett ChargeUp (10,000mAh)
The 99.95 Cygnett ChargeUp is a rubberised power bank with a strong plastic shell and a tiny LED display near its power button. It has two USB-A ports for charging at a total power output of 4.2 amps (2 ports at 10.5 Watts, 5V 2.1A) so you’ll be able to top up two power-hungry devices at a reasonable pace simultaneously. Recharging happens over its microUSB port.
It’s the smallest and slimmest of the three here, and has curved edges that mean it won’t scratch your phone screen if you’re keeping the two in the same while it charges. Its coup de grace, though, is that small screen that shows you the percentage of its state of charge: the best possible way to find out how many more boosts you have in store for your phone.
Cygnett sells the ChargeUp in 10,000mAh, 6000mAh and 4000mAh capacities with that very useful state-of-charge display, and as a Sport version that’s a little chunkier and more rugged but without any status read-out on how full or empty it is. And there’s also a small version that has a built-in microUSB cable.
Tronsmart Presto (10,400mAh)
The circa-50 Tronsmart Presto is the cheapest of this set of three, but it’s not the least technologically advanced. If you’re blasting through charges for multiple devices over and over, you’ll really like the fact that the Presto is Quick Charge 3.0 (15 Watts, 5V 3A) compliant through USB-C — so it’ll charge itself very quickly from any half-decent wall charger, and then deliver that charge just as fast to your phone.
I use the Tronsmart Presto with my sexy sexy Belkin DuraTek USB-C cable and it is phenomenally good at quickly charging two things: my Telstra Nighthawk M1 hotspot and my Samsung Galaxy S8 Plus. Both have pretty good battery life on their own, but I am the definition of heavy user, and the USB-C charging means they both get topped up very quickly.
Only one caveat: the Presto is quite large, a little bit ugly, and it’s only available in a 10,400mAh capacity. [Tronsmart Presto]
Belkin Mixit (10,000mAh)
The 119.95 Belkin Mixit is a sturdy piece of kit. It’s wrapped in a metal shell, has two USB-A power output ports and microUSB recharging, and supports 4.8 amps’ (2 ports at 12 Watts, 5V 2.4A) total output — which means you can charge two devices simultaneously at the full potential of the (regular, non-Quick Charge, non-proprietary) USB standard.
The bets feature of the Mixit is that if you’re charging a microUSB phone, you can keep that cable hidden away and charge your phone when you need it, then charge the power bank itself from any wall outlet. Plus, you can buy one in gold. Why would you not want one in gold?
You can buy the Mixit in a USB-C version too, although only in a 6600mAh battery size. Without the integrated charging cable, you can also find the Mixit in 10,000mAh, 6600mAh and 4000mAh capacities. [Belkin Mixit]

Tronsmart Presto Portable Charger: A battery bank with Quick Charge 3.0 built-in
Portable chargers and battery banks are in kind of a weird place right now. Battery life on phones is getting much better, but there’s still a market for these guys because it’s not good enough yet. A dead phone is no fun so, why not protect yourself with a battery? At least, that’s what Tronsmart thinks. That’s why it recently released the Presto Portable Charger. What makes the Presto stand out is the inclusion of Quick Charge 3.0, the fastest charging standard on the market today.
Tronsmart thinks the combination of that Quick Charge 3.0 charging speed and the 10,000mAh capacity will help it stand out in the crowded marketplace of portable chargers. We’ve been testing out the charger for a few weeks now and have come away impressed with the quality of it. While it isn’t a product that you need to run out and purchase this second, we definitely think that if you’re in the market, you should give it a look.
Charging
As we said, the standout feature is that Quick Charge 3.0 charging speed. We used the Presto charger, a Choetech USB A to USB C cable, a Kurrent Voltage Meter, and an LG G6 to conduct our charging test. Over three separate tests, our speed bottomed out at 1.12A, topped out at 1.8A and normally remained in a zone 1.42A – 1.57A. We tested this while the phone was between 20 and 70 percent battery so there were no limiting factors.
Overall, we’re pleased with the charging speed. It does trigger the “fast charging” notification on both the LG G6 and Samsung Galaxy S8 Plus and charges the phones up quickly. We replaced our wall charger at night with the Presto charger for eight nights and always woke up with a full battery and no problems.
Our charging capacity test was less than impressive. While the Presto charger is rated at 10,000mAh capacity, we only got about two full charges on our Samsung Galaxy S8 Plus (3500mAh battery capacity) and just over that on our LG G6 (3300mAh). While you do have to factor in some loss due to heat loss and some loss due to the cable, that was more than we thought was acceptable. Tronsmart claims on its Amazon listing for this charger that it achieved a 90% conversion rate, but we saw nowhere close to that.
Construction
On the other hand, the Presto is very well built. The soft plastic outside feels sturdy with no flex at all when pressure was applied to it. I have zero doubt that the charger will hold up well if it’s thrown into a bag or tossed around and suffers some bumps. It might get a little marked or stained up as ours did in the couple of weeks we had it, but it should still function flawlessly.
The right side of the device houses a power button that lights up the battery indicator on the face of the device. There are four little LEDs that light up to tell you how much juice is left in the bank, a very simple yet effective design. The bottom of the battery bank houses three ports, a green USB port that can charge devices up to Quick Charge 3.0 speeds, a regular USB port that charges at sub-Quick Charge speeds (save this one for your friends with Apple devices) and a micro USB port that sits in between them to charge the battery bank back up.
Ugh
Here is my biggest complaint with the Tronsmart Presto charger. Micro USB. It’s 2017 guys. I get that micro USB is legacy and there are a ton of cables out there, but UBS type-C is the name of the game right now. If you replaced the micro-USB port and the USB 3.0 port with one USB type-C port, you could have kept all the functionality and lost an unneeded port. USB type-C is the future and the reason I know that is that almost every phone sold today has a USB type-C port on it. Please, get with the times.
Conclusion
It does have that durability going for it though. And to be honest, it looks pretty nice too. I’m not too obsessed with how my battery banks look, but if I can get one that looks better, then I will. No need for obnoxious colors or designs.
The Tronsmart Presto Portable Charger is a solid option and well worth the 20 or so it’ll run you on Amazon.
