Actual Capacity

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: 13,300mAh
    • Switch Charging: 10,900mAh

Actual capacities are estimates are based on capacity testing and calculation.


First Impression

The Solice 20000 Type-C comes across as the generic version of a power bank. It does what other 18W USB-C PD and Quick Charge power banks do. And at a significantly lower price. But the packaging is blank. The user manual has no useful information (specs, support, warranty). And the power bank itself is plain. Except for the charge indicator. It is four LEDs like more power banks. But they form a circle around the power button. As you use up 25% a quarter of the circle disappears. Solice did tell me they are working on a design for the box. And to be fair most of us toss the box and user manual after a few days. If you don’t like logos on your products then this one will make you happy. The built-in flashlight could be handy in some cases. You turn it on by pressing and holding the power button. The power bank is also oversized for its capacity, similar to RAVPower models.

Power Meter Readings

iPhone 8 power negotiation

iPhone 8 power negotiation

The iPhone 8 fast charges when using a USB-C to Lightning cable. We see the usual power negotiations. Connection starts at 5V, then moves up to 9V. Learn more about fast charging iPhones.

The Quick Charge port (orange USB-A) also supports Apple 2.4A. That is an older fast charging standard, but it still works with newer iPhones. It charges near the same rate as USB-C PD when the iPhone’s battery is 30% or more charged. It is 1-2W slower at lower levels, but still faster than normal charging.

If you connect to the regular USB-A port the draw is under 5W.

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 ~50% 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.

Switch power negotiation

Switch power negotiation

The Nintendo Switch charges at the expected rate with a 12V charger. Chargers which offer 12V but not 15V will under perform with the Switch. It under draws power, maxing out below the 18W a 9V or 15V charger provides. The issue is with the Switch, not the charger. Please note 12W is still more than enough to charge the Switch in handheld mode while you play. Learn more about charging the Switch.

The PD protocol negotiation with the Switch is typical. It connects at 5V and moved up to 12V after negotiations. Current steps up once the 12V connection is made.

Different Power Profiles for Different Connections

*Solice lists the USB-C output as being 5V/3A, 9V/2A, 12V/1.5A. But my Power Delivery sniffer identified it as 5V/2A, 9V/2A, 12V/1.5A. I’ve run into this before. The 5V/3A is supported for regular USB-C connections. But under Power Delivery connections it is only 5V/2A.

For most use cases of this power bank it isn’t a problem. USB PD phones will charge at 9V. Other Android phones will use Quick Charge. Or limit themselves to 5V/2A already over USB-C. The Nintendo Switch and larger devices will default to 12V. And regular USB-C devices still have access to 5V/3A. I’m not aware of any USB PD device which only charges at 5V.

Fast Charging Standards Over USB-C & USB-IF Specifications

Solice 20000 Type-C ports and flightlight

The Solice’s USB-C port supports both USB Power Delivery and Quick Charge 3.0. The presence of Quick Charge 3.0 on the USB-C connection is against USB-IF specifications.

USB-C includes communication lines, along with power and data lines. The comm lines allow power negotiation without disrupting data transfers. USB Power Delivery uses these comm lines. As does Quick Charge 4+. But fast charging standards which pre-date USB-C do not. Instead they manipulate the data lines to negotiate power. That go against USB-C specifications, as it disrupts data transfers. But one doesn’t use data transfers with a dedicated charger.

In 2016, some USB-C chargers started offering Quick Charge 3.0. A few USB-C focused engineers warned against this practice and cited USB-IF specifications. But the predicted consequences were vague. As it turned out, nothing bad happened. Since then many chargers have operated this way, against specs. But there have been no reports of real world issues.

I have also not run into any issues with these fast charging standards on this or any other charger. But you should be aware of all the information before buying.

If you’re a stickler for meeting USB-C specifications this isn’t a good charger for you. If you’re more pragmatic it works well and has no known issues.

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 Solice power bank supports pass through charging a couple of ways:

  • Input: USB-C, Output: USB-A
  • Input: micro-USB, Output: USB-C or USB-A

Under all conditions both input and output drops to 5V when using pass through charging. This means no fast charging standards will be available. To reset the power bank for fast charging you’ll need to disconnect both the power source and connected devices.

With USB-C as the input the Quick Charge port (orange USB-A) offered almost 2A to the Mogo G6. The regular USB port offered about half that.

With micro-USB as the input the USB-C port offered up to 1.6A to the Moto G6. Both USB-A ports had far less output, though the QC port offered more than the regular port.

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 Solice 20000 Type-C is a low cost power bank with a lot of capacity. It is ideal for fast charging most model phones, providing 3-4 recharges. But with the low cost come some compromises. It is large and heavy for its capacity, more so than its peers. Its output limits it to smaller devices. And Solice doesn’t have the same support structure of larger brands.

Its 18W USB-C PD will fast charge Power Delivery supporting phones and small tablets. The Nintendo Switch will charge while you play in handheld mode. Though not as fast as possible (13W vs 18W). The 2018 iPad Pro will charge as well as with its own charger, but it can charge faster with a 45W power bank.

Quick Charge 3.0 is available on both the USB-C port and one of the USB-A ports. Quick Charge over USB-C is against USB-C standards, but isn’t know to actually be a problem. Read the detailed section above for more. Over USB-C Samsung and QC supporting Android phones should fast charge. Over USB-A those same phones, plus Motorola models, will fast charge. Either way you’ll need to provide the cable.

You can use all three USB ports at once. But you can only fast charge with a single device connected. Connecting a second device resets the circuit. All connections drop to 5V with at most 2A current. The Moto G6 went from 16W to 10W. And the Nintendo Switch went from 13W to 7.5W. Those rates are fine for charging overnight. But if you need to fast charge keep it to one device at a time.

About Solice

Solice doesn’t have their own website. You can contact them through their Amazon portal. Or via email. They offer a 12 month warranty and 30 day return.

Bottom Line

The Solice 20000 Type-C is a low cost, high capacity power bank. It’ll fast charge most phones and keep them charged for days. And charges the Switch while you play. But it is bigger and heavier than necessary. And doesn’t have the refinements found on more expensive brands.
