Three slim rectangular power banks in red blue and black lying side by side

Corn Electronics

Corn Electronics 3-Pack 10000mAh Power Bank (Red, Blue, Black)

SKU CH-GSFZ-QBQGD

Three 10000mAh power banks with dual USB outputs up to 5V 2.1A and USB-C plus Micro-USB inputs recharging in 5 hours

  • Three packs give backup power anywhere without a wall socket
  • Each 10000mAh unit delivers up to 2.4 full charges for iPhone X
  • Dual USB outputs share 5V 2.1A for two devices at once
  • Li-polymer cells keep weight to 218g and thickness to 14mm
  • Recharges via USB-C or Micro USB in 5 hours at 5V 2.0A

Three-pack daily carry

Three 10000mAh power banks ship in red, blue and black so each user or bag gets its own unit. Each pack stores 37Wh and weighs 218g at 14mm thick, making it easy to pocket or stow in a laptop sleeve. Dual USB-A outputs deliver up to 5V 2.1A per port while USB-C and Micro-USB inputs recharge the bank in five hours at 5V 2.0A. The lithium-polymer cells meet CE, FC and RoSH certifications.

Phone users who want cable-free days

Commuters, students and travellers who need multiple full phone charges between wall outlets will appreciate the 2.4× iPhone X or 3.6× iPhone 8 capacity per unit. Households sharing one colour per person avoid cable mix-ups. Buyers who need laptop-grade Power Delivery, wireless charging or a single higher-capacity block should look at something else. The 5V 2.1A ceiling also limits fast-charge protocols on newer flagships.

Fits in any small bag or desk drawer

Each brick measures 5.5 by 2.6 by .6 inches, so three sit side-by-side in a shallow organizer tray. USB-A cables you already own plug straight in; the USB-C input lets you top up the bank from the same charger that powers a modern phone. No AC adapter is included, so a 5V 2.0A wall wart is required to hit the five-hour recharge spec.

Questions about this item

What devices do I need to recharge each power bank using its Micro-USB or USB-C input?

A wall charger or other USB power source that can deliver 5 V at 2.0 A through a Micro-USB or USB-C cable will refill the 10000 mAh cell in about 5 hours.

Can I still charge an older phone that only draws 1 A from the two USB-A outputs?

Yes, each USB-A port supplies up to 5 V 2.1 A and automatically provides only the current the connected device requests.

How can I confirm a pack is delivering its rated 5 V 2.1 A output after I plug in my phone?

Use a USB power meter on the cable; it should show 5 V and up to 2.1 A while the phone is drawing maximum current.
