A lantern that doubles as a power station

The Streamlight Super Siege answers a question the rest of the Siege family doesn't ask: what if your lantern also kept your phone alive through a three-day outage? Built around a large 8,800 mAh rechargeable lithium-ion battery, the Super Siege pushes 1,100 lumens on high — more than double the standard Siege — and hands you a USB port that charges phones, tablets, and other Streamlight USB devices. It's the flagship of the Siege line: the biggest, brightest, and most capable, with the weight and size to match.

1,100 lumens and a real battery bank

The white C4 LEDs run high at 1,100 lumens for about 5.75 hours, medium at 550 for 11.5, and low at 125 for 36.25 hours — honest ANSI-rated figures. Four red LEDs preserve night vision: red high at 2.7 lumens for 140 hours, red low at 1 lumen for 348 hours, and a flashing SOS mode for 320 hours. But the headline is the 8,800 mAh battery behind it all. The USB output charges most smartphones several times over (Streamlight rates it at four or more full smartphone charges and a couple of tablet charges), making this as much a power bank as a light. Recharging takes about 7 hours with the included AC charger.

Same Siege toughness, plus a dry box

Everything that makes a Siege a Siege is here: IPX7 waterproof to one meter, a buoyant body that floats, 2-meter impact resistance, and an unbreakable polycarbonate lens. New for the flagship: a watertight storage compartment in the base for keys, matches, or a phone, and the removable Glare Guard for close-up task lighting. The removable polycarbonate cover gives full 360-degree area light; pop it off and the Glare Guard turns it into a work light. D-rings top and bottom, a locking ergonomic handle with an incorporated hook, rubber-molded base for grip on wet surfaces, and the familiar battery-level indicator (green to yellow to red to flashing red) round out the package.

The rechargeable trade-off

At 1 lb 14 oz, the Super Siege is the heaviest lantern in our lineup and far too bulky for a bug-out bag — this is a base-camp, truck-bed, and home-outage lantern. And unlike its alkaline siblings, it needs a maintenance charge every few months to keep the lithium cell healthy; an alkaline Siege can sit in a closet for years on its D cells. What you get in return is freedom from disposable batteries entirely, plus real device charging. For households that want one lantern to cover a long outage — light the room and keep two phones alive — the trade is worth it.

Pros

• 1,100-lumen high mode — the brightest lantern we review
• 8,800 mAh battery doubles as a USB power bank (multiple phone charges)
• Long runtimes at every level, including 36+ hours on low
• Red night-vision modes with 140–348 hour runtimes
• IPX7 waterproof, floats, 2-meter impact resistance
• Watertight base compartment for small essentials
• Removable Glare Guard for task lighting; battery-level indicator

Cons

• Heavy at nearly 2 lbs — not a packing lantern
• Rechargeable cell needs periodic top-ups in storage
• 7-hour recharge time with the AC charger
• 5.75 hours on high means heavy use needs the low/medium modes
• Premium size and weight for a single-purpose light

Specs

Frequently asked questions

Can it really charge my phone? Yes — the 8,800 mAh battery feeds a USB output that charges most smartphones several times and tablets roughly twice, per Streamlight's own ratings. Think of it as a lantern with a serious power bank inside.

How long does it take to recharge? About 7 hours with the included AC charger.

How does it differ from the standard Streamlight Siege? The standard Siege runs on disposable D cells and tops out at 540 lumens. The Super Siege is rechargeable, hits 1,100 lumens, and adds USB device charging plus a watertight storage compartment. It's bigger, heavier, and more capable.

Will the battery go bad sitting in a closet? Lithium batteries self-discharge slowly, so give it a top-up every few months if it's stored for emergencies. That's the one maintenance cost versus the alkaline models.

Verdict

The Super Siege is for the household that wants one lantern to rule a long outage: 1,100 lumens to light the house, weeks of runtime on the low modes, and enough battery to keep the family's phones breathing. It's heavy and it demands the occasional recharge in storage, but no other lantern here does more in a single package. If your emergency plan is "ride it out at home," this earns its shelf space.
