6-Bay 18650 Battery Holder – 10W Fast Charging – Digital Display – Dual USB + Type-C – Wireless Charging Power Case – DIY No-Solder Assembly

You've got a pile of 18650 batteries lying around—from old laptop packs, flashlights, or other devices. They're still good, but you don't have a way to actually use them as a portable power bank.

This housing turns those batteries into a functional power bank. No soldering, no complicated wiring—just load your cells, screw it closed, and you're ready to go.

No-solder DIY design – easy assembly

No soldering iron required. The housing uses screw terminals that make contact with the battery ends. Just drop your 18650 cells in, align the positive and negative ends correctly, and close the case. Swap batteries out anytime without damaging the shell.

Six-cell capacity – plenty of power on hand

Holds up to six standard 18650 batteries. The more cells you load, the more capacity you get. Use new or lightly used ternary lithium cells for the best performance. Avoid worn-out or low-quality batteries—they won't deliver stable output.

Digital display – battery level at a glance

A built-in screen shows remaining power, so you always know how much juice is left. No guessing, no unexpected shutdowns.

Three output ports – charge multiple devices

Two USB-A ports and one Type-C port. Each port works independently, so you can charge multiple phones at the same time. Keep in mind—this is for phones and small devices, not tablets or laptops.

10W fast charging – solid for daily use

Supports up to 10W output. Not the fastest charger on the market, but more than enough for topping off phones during the day.

Built-in flashlight – useful for camping or bedside

The housing includes a bright lamp. Switch it on for outdoor camping light, or dim it down as a soft bedside night light. Practical for everyday use and outdoor trips.

Versatile use – fits into daily life

• Home standby – keep it charged and ready

• Short trips – toss it in your bag for extra power

• Camping – power your phone and light up your tent

• Outdoor sports – reliable backup when you're away from outlets

A couple of things to keep in mind

Batteries are not included. You supply your own 18650 cells.

Always check polarity when installing batteries. Reversing the connection can damage the board or the batteries themselves.

Use quality cells. Old or damaged batteries won't hold a charge and may not deliver consistent output.
