All power banks list their capacity (mAh) based on the nominal voltage of the battery cells. It does not accurately represent how many recharges you’ll get with the power bank. Actual capacity shows how much power you’ll actually get from a power bank.
You can divide the actual capacity below by your device’s battery capacity. That will give you a realistic estimate on the number of charges it will provide.
- Listed Capacity: 20,000mAh
- Actual Capacity:
- Phone Charging: 13,200mAh
- Switch Charging: 12,500mAh
- Laptop Charging: 9,300mAh
Actual capacities are estimates are based on capacity testing and calculation.
The Omars PowerSurge 20000 45W USB-C PD has a metal exterior, except for the sides and LCD display. That’s always nice to see for durability and heat dispersion. But it also makes the power bank heavier. And this one is heavy enough, having nearly the same size and weight of an Anker PowerCore+ 26800 PD. But 25% less power capacity. The display shows the remaining charge of the power bank, from 0-100. Much better than 4 LED lights, but treat it as more of an estimate. The USB-C and Quick Charge ports are on opposite sides, making it easy to deal with two cables at once.
Power Meter Readings
If you connect to the USB-A port it’ll charge ~30% slower.
The Moto G6 fast charges using the Quick Charge port (orange USB-A). This will be the same for Samsung and Quick Charge enabled Android phones. If connected to the USB-C port it’ll charge ~40% slower. The Google Pixel and Android phones that support USB Power Delivery will fast charge on the USB-C port. Learn more about fast charging various Android phones.
The Nintendo Switch charges at its max rate, charging while you play. Its charge rate while sleeping is also normal. This charger can also power the Switch’s dock. Learn more about charging the Switch.
The PD protocol negotiation with the Switch is typical. It connects at 5V and moved up to 15V after negotiations. Current steps up once the 15V connection is made.
MacBook Pro, 13-inch
As a 45W charger it can support 12-inch laptops. As well as 13-inch models running office, Internet, and entertainment apps. If playing video games or using CPU intense apps it may only extend battery life. But either way you get a lot more uptime. Learn more about charging USB-C laptops.

Using the Included USB-C to micro-USB Adapter
As a general rule it is safe to use a USB-C to micro-USB adapter. Such as the one Omars included. It is an adapter that connects to a micro-USB cable, giving it a USB-C end. It is not safe to use the opposite, turning a USB-C connection into any kind of other connection. That would allow for connections against USB standards, and dangerous to devices. Again, the adapter Omars included is the good kind.
My USB tester showed the micro-USB cable with USB-C adapter has a 56k Ohm resistor. That resistor is required under USB-IF rules for all USB-C to USB-A connecting cables.
The cable fast charged my Moto G6 at the same rate as a regular USB-C to USB-A cable. Both allowed the Moto G6 to draw 16W from the USB-A Quick Charge port.
Pass Through Charging
Pass through charging allows a power bank to both recharge and charge a connected device. Some of the energy flows from the wall output, through the power bank, to the device. The remaining energy recharges the power bank itself.
The Omars PowerSurge 20000 supports pass through charging:
- Input: USB-C, Output: USB-A
You can use either USB-A port to charge while the power bank re-charges. The Quick Charge port continued to offer high output during pass through.
Pass through charging is useful for overnight stays with limited wall chargers. It is not recommended to do so on a regular basis. It puts more heat and stress on the power bank, which can affect its lifespan. Doing it when traveling is fine. But don’t set this up next to your bed at home every night.
The Omars PowerSurge 20000 45W USB-C PD is a high output and high input power bank. Great for larger USB-C devices up to a 13-inch laptop. Its LCD shows the remaining charge percentage. That is way more informative than 4 LED lights. But it has the same inaccuracies more power banks do, especially below 50%. During a capacity test it dropped faster than before below 50% and again below 20%. Be aware it is more of an estimate.
Its 45W USB-C output works well for small to medium sized USB-C devices. Especially phones and tablets that support USB Power Delivery, the Nintendo Switch, and up to 13-inch laptops. The Quick Charge port fast charges Samsung, Motorola, and QC supporting Android phones.
Unlike some of its peers, it also supports 45W input via USB-C. This is rarer than it should be, given 45W output power banks have larger capacities. By offering 45W input (and assuming you use a 45W USB-C PD wall charger) this power bank will recharge up to 33% faster.
The 20,000mAh capacity doesn’t do much for the size and weight. It is as wide as some 26,800mAh power banks, and almost as heavy. With less up time for your devices. It is enough to double the run time of most small laptops. But after that you’ll need to find a wall outlet.
Omars has U.S. based support (web, email) and a 12 month warranty on both Omars and Novoo branded products.
The Omars PowerSurge 20000 45W USB-C PD provides high output, and re-charges fast with high input. Good for keeping your small to mid-sized laptop running for a few more hours on the go. While also fast charging most phones. But bigger and heavier than it needs to be.Buy on Amazon
