Eventek 20000mAh Rechargeable LED Camping Lantern - Ultra Br
✅ PROS
- Massive 20000mAh battery doubles as a power bank — charges a smartphone roughly 4-5 times
- Four brightness modes plus SOS strobe, ranging from a dim 100-lumen mode for tent reading to a blinding 1000-lumen max
- IPX5 water resistance handles rain and splashes without flinching
❌ CONS
- At 1.2 pounds, it's noticeably heavier than single-purpose lanterns — backpackers will feel the weight
- The included micro-USB cable feels dated; you'll want your own USB-C or a faster wall adapter for the 8-hour full charge
The Verdict
The Eventek 20000mAh Lantern: A Powerhouse That Does Double Duty
Most camping lanterns are single-purpose gadgets. You hang them, they glow, they die, and you replace the batteries. The Eventek 20000mAh Rechargeable LED Camping Lantern tries to be more — and for the most part, it pulls it off. This isn’t just a light source; it’s a portable power station with a bulb attached. The question is whether that added versatility justifies the extra bulk.
What You Actually Get
Out of the box, you get the lantern itself (measuring roughly 5.5 inches tall with a 3.5-inch diameter base), a micro-USB charging cable, and a small carabiner for hanging. That’s it. No wall adapter, no carrying case. The build is rugged plastic with a rubberized base that grips surfaces well. The top handle folds flat when not in use, and there’s a metal loop underneath for hanging the lantern upside down from a tent ridge or tree branch.
Performance and Real-World Use
The headline feature is that 20000mAh battery. In testing, that translates to roughly 4-5 full smartphone charges — enough to keep your phone, GPS, and headlamp alive for a long weekend. The USB output port sits under a rubber flap on the side, and it pushes out a respectable 5V/2.1A, which charges most phones at standard speed, though not fast-charging speeds.
The lighting modes are where this thing earns its keep. The bottom dial cycles through four settings: a low 100-lumen mode (perfect for reading without blinding your tentmate), a medium 400-lumen setting, a high 700-lumen mode, and a max 1000-lumen blast that floods a campsite. There’s also a red SOS strobe for emergencies. The light diffuses evenly through the frosted dome, so you don’t get that harsh spotlight effect you see with cheaper lanterns.
Battery life scales with brightness. On low, you’re looking at 40+ hours. Crank it to max, and you’ll get around 5-6 hours of continuous light. The digital battery indicator on the side is a nice touch — four small LEDs show remaining charge, so there’s no guessing when it’s about to die.
The IPX5 water resistance is legit. I tested it under a running tap and in a light rainstorm; the internals stayed dry. It won’t survive being submerged, but it’ll handle everything short of dropping it in a lake.
What Buyers Consistently Praise
Across the 229 ratings, the recurring theme is versatility. One reviewer wrote, “This lantern replaced both my old battery-powered lantern and my separate power bank. Two pieces of gear, one device.” Another noted, “The 1000-lumen setting lit up our entire campsite for a group of six — nobody tripped over a guy line all weekend.”
The battery indicator also gets consistent love. Multiple reviewers specifically mentioned how much they appreciated knowing exactly how much charge remained, something cheap lanterns never offer.
Where It Falls Short
Honestly, the weight is the biggest tradeoff. At 1.2 pounds, this is not a backpacker’s friend. If you’re hiking 15 miles to a backcountry site, you’ll feel every ounce. This is a car camper’s or base camp lantern, not an ultralight option.
The micro-USB charging port is also showing its age. A full charge from empty takes roughly 8 hours, and that’s with a decent 2A adapter. If you’re using the included cable with a phone charger, expect closer to 10 hours. USB-C with fast charging would have made this a truly modern device.
One more nitpick: the 100-lumen low mode is still fairly bright for tent use. A true moonlight mode (10-20 lumens) would have been nice for late-night bathroom trips without blinding yourself.
Who Should Buy This
This lantern hits a sweet spot for three specific types of shoppers:
- Car campers and glampers who want one device for both light and phone charging
- Emergency preparedness folks building a home kit — this doubles as a power bank during outages
- Fishing and tailgating enthusiasts who need reliable light and juice for multiple devices
Skip it if you’re an ultralight backpacker or if you already own a dedicated power bank and just want something small to light up your tent.
FAQ
Q: Can it charge a tablet? A: Yes, but slowly. The 5V/2.1A output will charge an iPad or similar tablet, just not at fast-charge speeds. Expect roughly a 50% charge per hour.
Q: How long does the battery last on a full charge? A: Depends on mode. Low gives you 40+ hours, medium around 15-18 hours, high about 8 hours, and max brightness drains it in 5-6 hours.
Q: Does the lantern work while charging? A: Yes, it does. You can run it plugged into a wall outlet or power bank, which is handy for extended outages.
The Verdict
Buy it if you want a do-everything light source that also keeps your devices alive on multi-day trips. The 20000mAh capacity, four brightness modes, and IPX5 rating make it a genuinely useful piece of gear.
Skip it if every ounce matters in your pack, or if you already own a separate power bank and just need a basic tent light.
At 4.6/5 stars, this is one of the most versatile camping lights in its price range. It’s not perfect — the weight and old-school charging port hold it back from a perfect score — but for car camping and emergency use, it’s hard to beat.
