Review: One of the best portable chargers - Incredible battery, such a large storage capacity. The in-built cable is super handy, means i dont need to lug another cable around with me. It's not the smallest but that being said it's a good size for how large a capacity it is. Super quick to charge the charger, and also outputs well - can charge my iPhone super speedily. A great price for all of that. The display is also super handy so you can see exactly how much juice is left in it.
Review: A powerful and convenient charger that's become my everyday essential. - I've owned a lot of power banks over the years, but they all had the same problem: they were useless if I forgot to bring the right cable. This Anker 20,000mAh power bank completely solves that. The built-in USB-C cable is an absolute game-changer. It tucks away neatly into the side of the unit, and it means I can just grab the power bank and go, knowing I have everything I need to charge my phone. The capacity is massive. 20,000mAh is enough to charge my phone (a Samsung Galaxy) at least three to four times from empty, with some juice still left over. It's perfect for a long weekend away, a festival, or just for those busy days when I'm away from a wall socket for a long time. It also charges my tablet and headphones without any issues. Beyond the built-in cable, it's also got a standard USB-C port (which works as both an input to charge the power bank and an output) and a USB-A port, so you still have the flexibility to charge older devices or help out a friend who has a different type of phone. The charging speed from the built-in cable is great, supporting fast charging for my phone. In terms of design, it's about what you'd expect for a high-capacity bank – it's got some heft to it, but it's slim enough to slide into a backpack or a large coat pocket without being too obtrusive. There's also a handy little button on the side with a circular display that shows you the exact percentage of battery remaining, which is much better than the vague four-dot systems on older models. Verdict: This is pretty much the perfect power bank for anyone with a modern USB-C phone. The combination of huge capacity, multiple ports, and the sheer convenience of the integrated cable makes it a top-tier product. It’s reliable, well-built, and has replaced all my other portable chargers.

## Questions & Answers

**Q: Why is my power bank providing fewer charges than expected?**
A: The capacity reduction during charging is due to a 30% to 45% energy loss in the battery cells and conversion circuitry. Therefore, a fully charged Anker A1383 Power Bank (PowerCore 20K) offers an estimated 11,000mAh to14,000mAh to power devices.

**Q: How can I estimate the number of charges for my device?**
A: To estimate charging cycles, use this formula (Power Bank Capacity × 0.65) ÷ Device Battery Capacity ≈ Number of Charges. For instance, charging a 3,000mAh device using a 20,000mAh power bank would offer approximately 4.33 charges.

**Q: How long does it take for the power bank to recharge?**
A: It depends on the charger's power and the ambient temperature. The A1383 model, when using a 30W PD charger at 77°F (25°C), takes about 4.5 hours to recharge.

### ⭐⭐⭐⭐⭐ Amazing powerbank for the SteamDeck!
*by M***Y on 3 February 2025*

Ok so I desperately needed a powerbank for my SteamDeck as I have the LCD model and the battery life is really bad especially when I'm playing demanding games on the go. After testing for a few weeks here are the results: 4 hours 10 mins - Playing SF6 offline uses 15-17w (SteamDeck fully charged at 100%) Charging times using 67w charger: 1 hour 52 mins - 0% - 100% 1 hour 39 mins - 8% - 100% Powerbank at 100% charging SteamDeck from 2% - 99% 2 hours 32 mins - (SF6 running in the background) The SteamDeck got to around 90% in just over 2 hours but from 90-99% it was charging really slowly. This left the powerbank with 32% remaining Powerbank 32% remaining - 1 hour 14mins - charging SteamDeck from 0% - 56% All in all I'm very happy with the powerbank as it gives me an additional 3-4 hours of play time depending on how high I want the settings to be. Usually I'd sacrifice high graphics for battery life as I'm usually gaming on the go. The specs state that it fully charges in 90mins but that isn't true. It is a little heavy so I definitely wouldn't use this in handheld mode whilst attached to the back so I normally place it on the table and connect a PS4 controller and play it in table top mode. The built in cable is really useful but because I have to plug it on top of the SteamDeck it means the cable is slightly twisted. Using the built in cable as well as the USB C port and a 5A cable, it does charge my Samsung Galaxy Note 10+ 5G in Super Fast Charging 2.0. I picked this up during the sale period and for £36 it's a steal! UPDATED REVIEW!!! After using a different 65W USB Type C charger, it does actually fully charge from 0% - 100% in 1 hour 35 minutes so I guess the charging times listed is pretty accurate!
