Qubii Power vs Qubii Duo: Which One Is Right for You? (2026 Comparison)
Qubii Power ($89.99) and Qubii Duo (from $54.99) are both automatic phone backup devices made by Maktar that save your photos, videos, and contacts to a microSD card while you charge. The key difference: Qubii Power is a standalone USB-C GaN fast charger (50% battery in 30 minutes) with Infineon encryption and a 10-year warranty, while Qubii Duo is a smaller backup cube that plugs between your existing charger and cable, available in USB-A or USB-C, starting at a lower price point.
If you're trying to decide which one to get, this side-by-side comparison covers every difference that matters — price, charging speed, size, encryption, warranty, and real-world use cases. Both devices are excellent. The right choice depends on what you already own and what you value most.

The table shows the key trade-off clearly: Qubii Power costs more but includes everything (charger, encryption, 10-year warranty). Qubii Duo costs less but relies on your existing charger and lacks hardware encryption.
Charging Speed: 30W GaN vs Your Existing Charger
This is the single biggest difference between the two devices.
Qubii Power has a built-in 30W GaN (gallium nitride) fast charger. GaN technology allows for a more compact design while producing less heat than traditional silicon chargers. In practice, this means:
- 0% to 50% battery in approximately 30 minutes
- 0% to 100% battery in approximately 90 minutes (varies by phone model)
- Supports 100-240V — works in any country
Qubii Duo does not have a charger. It sits between your charger and your cable, passing through whatever power your charger delivers. If you already own a 30W+ USB-C charger, your charging speed through Qubii Duo will be similar to Qubii Power. If you're using the 5W charger that came with an older iPhone, charging will be slow regardless.
Bottom line: If you don't already own a fast charger, Qubii Power eliminates the guesswork. If you already have a good fast charger, Qubii Duo lets you keep using it.
Design and Portability
Qubii Duo is the smaller device. At approximately 17 grams, it's roughly the size of a sugar cube and fits easily in a pocket, purse, or laptop bag. Because it doesn't include a charger, it's lighter and more portable. Many users keep one at home and one in a travel bag.
Qubii Power weighs approximately 68 grams — about four times heavier, but still compact for a 30W GaN charger. It replaces your charger entirely, so you carry one device instead of two. For travel, Qubii Power is actually the more streamlined option because it's charger plus backup in a single unit with fold-out prongs.
If your priority is absolute minimum size and weight, Qubii Duo wins. If you want to reduce the total number of items in your bag, Qubii Power wins.
Compatibility: Both Work with iPhone and Android
Both Qubii Power and Qubii Duo are compatible with iPhones and Android phones. They back up photos, videos, and contacts automatically through the free Qubii app, available on the App Store and Google Play. Both support microSD cards up to 2TB — enough for hundreds of thousands of photos.
Cable compatibility:
- iPhone 15 and newer (USB-C): Works directly with Qubii Power and Qubii Duo USB-C using a USB-C cable
- iPhone 14 and older (Lightning): Use a Lightning-to-USB-C cable with Qubii Power or Qubii Duo USB-C, or a Lightning-to-USB-A cable with Qubii Duo USB-A
- Android phones (USB-C): Works with Qubii Power and Qubii Duo USB-C directly; use a USB-C to USB-A adapter for Qubii Duo USB-A
If your household has a mix of old and new devices, Qubii Duo USB-A offers the widest cable compatibility with no adapters. For a modern all-USB-C setup, Qubii Power or Qubii Duo USB-C is the cleaner choice.
When Qubii Duo Is the Better Choice
Scenario 1: You already own a fast charger. If you have a 20W or 30W USB-C charger from Apple, Anker, or another brand, adding a Qubii Duo USB-C between your charger and cable gives you automatic backup without replacing any of your existing gear. Total investment: $59.99.
Scenario 2: Budget is your top priority. At $54.99 for the USB-A version, Qubii Duo is the most affordable way to get automatic phone backup. You save $35 compared to Qubii Power and still get the same backup features — photos, videos, and contacts saved to a microSD card every time you charge.
Scenario 3: You need USB-A compatibility. Some older chargers, car chargers, and laptop ports are USB-A only. Qubii Duo USB-A plugs into any USB-A port, making it the most versatile option for setups where USB-C is not available everywhere.
When Qubii Power Is the Better Choice
Scenario 1: You want the simplest possible setup. Qubii Power is an all-in-one device — charger plus backup in a single unit. Plug it into the wall, connect your phone, done. No stacking adapters, no compatibility questions. For a step-by-step walkthrough, see our Qubii Power Complete Setup Guide.
Scenario 2: You care about data encryption. Qubii Power includes an Infineon hardware encryption chip that encrypts your backed-up data directly on the microSD card. This means if someone takes your microSD card, they cannot access your files without the Qubii Power unit that encrypted them. Qubii Duo does not have hardware encryption — though you can still set a PIN lock in the Qubii app for software-level protection.
Scenario 3: You want long-term reliability. Qubii Power comes with a 10-year warranty — five times longer than Qubii Duo's 2-year warranty. If you plan to use your backup device for many years (and most people do), Qubii Power's extended coverage provides additional peace of mind. The warranty covers manufacturing defects and hardware failure.
Also Consider: Piconizer 4
If neither Qubii model fits your needs perfectly, the Piconizer 4 (from $76.49) offers a different approach. Piconizer 4 is a portable USB-C flash drive that plugs directly into your iPhone or Android phone — no charger needed at all. It's ideal for quick file transfers, freeing up phone storage on the go, or backing up before travel when you don't have access to a wall outlet.
The trade-off: Piconizer 4 requires you to manually connect it when you want to back up, whereas both Qubii Power and Qubii Duo back up automatically every time you charge. For most people, the "set it and forget it" convenience of a Qubii makes it the better daily backup solution. Piconizer 4 shines as a complementary travel companion.

Frequently Asked Questions
What is the difference between Qubii Power and Qubii Duo?
Qubii Power ($89.99) is a standalone 30W GaN fast charger with a built-in microSD card slot, Infineon hardware encryption, and a 10-year warranty. It plugs directly into a wall outlet and replaces your existing charger. Qubii Duo (from $54.99) is a smaller backup cube that plugs between your existing charger and cable — it does not charge on its own. Qubii Duo is available in USB-A and USB-C versions. Both devices automatically back up photos, videos, and contacts to a microSD card while you charge.
Which Qubii should I buy?
Choose Qubii Power if you want fast charging built in (50% battery in 30 minutes), hardware encryption, and a 10-year warranty. Choose Qubii Duo if you already have a charger you like, want the most affordable option (from $54.99), or need a USB-A connection. Both work with iPhone and Android and support microSD cards up to 2TB.
Does Qubii Power charge faster than Qubii Duo?
Qubii Power has a built-in 30W GaN charger that delivers 50% battery in approximately 30 minutes. Qubii Duo does not have a built-in charger — your charging speed depends on the charger you plug it into. If you pair Qubii Duo with a 30W or higher charger, the charging speed will be comparable. Qubii Power is the simpler option because fast charging is guaranteed out of the box.
Do Qubii Power and Qubii Duo work with both iPhone and Android?
Yes. Both Qubii Power and Qubii Duo work with iPhones and Android phones. They support microSD cards up to 2TB and back up photos, videos, and contacts automatically through the free Qubii app (available on App Store and Google Play). For iPhones with Lightning connectors, use a Lightning-to-USB-C cable with Qubii Power or Qubii Duo USB-C, or a Lightning-to-USB-A cable with Qubii Duo USB-A.
Can I use the same microSD card in both Qubii Power and Qubii Duo?
Yes. Both Qubii Power and Qubii Duo use standard microSD cards (up to 2TB). You can move a microSD card between devices. However, if you enabled Infineon hardware encryption on Qubii Power, encrypted files can only be read by that specific Qubii Power unit. Non-encrypted files are accessible from any Qubii device.
Summary: Qubii Power ($89.99) is the all-in-one choice — fast charger, automatic backup, hardware encryption, and a 10-year warranty in one device. Qubii Duo (from $54.99) is the flexible, budget-friendly choice — it works with any charger you already own and is available in USB-A and USB-C. Both protect your photos without cloud subscriptions, without internet, and without monthly fees. You can't go wrong with either one.
