USB-C Port 1 — 140W max output
[PORT 01]
USB-C · 140W Max

A single port pushing 140W runs a MacBook Pro at full speed — no throttle, no trickle. Power a MacBook Pro (M4 Pro) to 50% in 27 minutes.

USB-C Port 2 — simultaneous charging
[PORT 02]
USB-C · Simultaneous

Two laptops running in parallel. The Apex distributes power intelligently across both USB-C ports — 300W total never gets divided unfairly.

USB-A Port — legacy device charging
[PORT 03]
USB-A · Legacy Ready

Every cable you already own still works here. Older devices, accessories, earbuds — plug them in without an adapter. No one gets left behind.

In and Out at the Same Time

Most power banks do one thing at a time: charge a device, or get charged themselves. The Apex does both simultaneously. The 250W dual-port input is the fastest in its class — recharging the bank to 40% in just 10 minutes while it's still delivering power to your laptop. At a layover, that matters. In a morning rush, that matters. The bank goes back in your bag full, not half-empty, because it was charging itself the whole time you were charging your devices.

The Display Tells You Everything

LumenCore Apex smart display and app control interface
[MONITOR]

The built-in display shows live wattage per port — not just a battery percentage bar. See exactly how fast each device is charging and whether a cable is limiting throughput.

[CONTROL]

The companion app lets you adjust output power manually, set charging limits for device longevity, and push firmware updates over Bluetooth.

[OPTIMIZE]

Per-device power allocation means nothing gets starved. When three devices are connected, the Apex distributes the available 300W based on what each device actually needs.

Packed it for a 9-hour flight and kept my laptop and phone running the entire way. The display showing live wattage is genuinely useful — I could see the moment a worn cable was choking the output. Swapped cables, jumped from 18W to 87W instantly. That feedback alone is worth it for anyone who travels with serious gear.

Retired IT, so I've owned more power banks than I can count. This one's different. It charges fast, it recharges fast, and the display finally tells me what's actually happening instead of making me guess. Only gripe: the weight catches you off guard the first time you pick it up. But that's the trade for 26,250mAh, and I'll take it.

Bought this for my partner — they shoot video on location and can't afford a dead laptop mid-session. Two months later, they've stopped carrying a wall adapter entirely. The bank covers the whole shoot day.

Engineering student here — the dual USB-C input at 250W is the spec that sold me. I can top it off between classes in about 13 minutes and leave with a full charge. Nothing else in this price range does that.

Set it on the charging base at my desk. Grab it when I leave. Come back, set it down. It's never empty when I need it. That's the whole workflow — simple, frictionless, always ready.

First high-wattage bank I've owned — previously relied on a budget 10,000mAh that could barely push my phone. The difference is stark. Charged my phone, my laptop, and my partner's tablet on a 6-hour drive without running below 30% capacity. The app is a nice bonus; not essential, but satisfying.

Questions

Why does it charge fewer times than the spec suggests?
Rated capacity (26,250mAh at 3.7V) converts to a lower effective output capacity when stepped up to 5V for device charging. Conversion losses and device-side charging circuits also affect total cycles. The display's live wattage readout helps you track exactly what's going into each device in real time.
Can it charge a device and recharge itself at the same time?
Yes — this is one of its key advantages. The dual USB-C input accepts up to 250W while simultaneously delivering output power to connected devices. This is called pass-through charging and it works both on and off the dock.
Why does output power decrease while the bank is recharging?
This is thermal management — a feature, not a bug. As the battery warms during fast recharging, the controller reduces charging current to protect cell longevity. You'll see the wattage numbers shift on the display as this happens. The bank includes multi-layer temperature monitoring for this reason.
Is it normal for it to feel warm during charging?
Yes. At 300W output or 250W input, some heat generation is expected and normal. The unit is built with safe temperature control technology that keeps operating temps within safe limits. If it ever becomes uncomfortably hot to the touch, stop use and contact support.
Is it actually TSA approved?
Yes. At 99.75Wh, it falls just below the TSA's 100Wh carry-on limit without requiring airline approval. It can go in your carry-on or personal item — no gate check needed. Checked bags are not permitted for lithium batteries regardless of size.
What's the best way to store it long-term?
Store at around 50% charge in a cool, dry location. Avoid leaving it fully charged for weeks at a time if not in use — this can degrade cell capacity over time. The included travel pouch keeps the ports protected during storage and transport.
