If you’re stuck choosing between the LanLuk 40800mAh, the RGVOTA 38800mAh, and the HELLEE 15000mAh power banks, I get it. They all promise to keep your devices charged, but they serve very different needs based on capacity and portability.
This comparison is for anyone who needs a portable charger for travel, daily commutes, or emergency backup. The big trade-off here is massive battery life versus pocket-friendly size. Let me break down exactly which one fits your life best.

The LanLuk is a beast at 40800mAh, and it’s the only one here with three built-in cables (USB-C and iOS outputs). I love that it charges up to 5 devices at once with 25W PD fast charging, making it perfect for long trips or camping. The main catch is that at 14.5 ounces, it’s not exactly pocket-friendly, and it cannot be carried on flights due to its size. If you need maximum power for road trips or emergency kits, this is the one.
✅ Pros
- Massive 40800mAh capacity for multiple full phone charges
- 3 built-in cables (iOS and USB-C) so you don’t need extras
- 25W PD fast charging charges phones up to 4x faster
- 3-year warranty included for peace of mind
❌ Cons
- Too large (14.5 oz) to carry on flights
- Heavy at 410g, not ideal for everyday pocket carry

The RGVOTA packs 38800mAh of power with 5 output ports and 2 inputs, making it a solid choice for charging a group of devices. I appreciate that it has over 1,400 ratings and a decade of brand history, which gives me confidence in its reliability. It’s still heavy at 15 ounces and cannot go on flights, but it’s slightly more affordable than the LanLuk and offers similar capacity. This is great for road trips where you need to keep multiple phones and tablets alive.
✅ Pros
- High 38800mAh capacity for extended off-grid use
- 5 output ports let you charge multiple devices at once
- Dual inputs (5V/3A) for convenient recharging options
- LED display shows exact remaining battery percentage
❌ Cons
- Heavy at 432.5g (15 oz) and not flight-safe
- No built-in cables, so you need to carry your own

The HELLEE is the lightweight champ here at just 7.09 ounces, and it’s the only one you can take on a plane. It has 6 output ports and a built-in cable, plus 22.5W fast charging that works with iPhones and Androids. The trade-off is a smaller 15000mAh capacity, so you’ll get maybe 3-4 full phone charges instead of 8-10. For daily commuting, business travel, or anyone who wants a slim power bank that fits in a pocket, this is the winner.
✅ Pros
- Ultra-light at 7.09 oz and small enough for a pocket
- Flight-safe, so you can take it anywhere
- 6 output ports and a built-in cable for convenience
- 22.5W fast charging with intelligent voltage regulation
❌ Cons
- Only 15000mAh, so less capacity for long trips
- No PD fast charging, max is 22.5W standard fast charge
Which One Should You Buy?
I’ve spent a lot of time with these three power banks, and honestly, the right pick comes down to one question: how much power do you really need to carry? Let me match you to the perfect one based on your situation.
LanLuk Portable Charger Power Bank 40800mAh with 3 Built-in Cables is right for you if…
- You’re going on a long road trip or camping and need to charge multiple phones and tablets for days without an outlet
- You hate carrying extra cables and want 3 built-in ones (iOS and USB-C) ready to go at all times
- You want the biggest possible battery at 40800mAh and don’t mind the 14.5-ounce weight
RGVOTA Portable Charger 38800mAh Power Bank with 5 Outputs & 2 Inputs is right for you if…
- You need to charge a group of friends or family at once with 5 output ports and a proven brand with over 1,400 ratings
- You prefer having dual input options (5V/3A) for recharging the battery pack itself more flexibly
- You want 38800mAh of capacity at a slightly lower price point than the LanLuk
HELLEE Power Bank, 15000mAh Portable Charger with Built in Cable is right for you if…
- You fly frequently and need a power bank that is flight-safe and weighs only 7.09 ounces
- You want something slim enough to slip into a pocket or small bag for daily commutes
- You only need to top off your phone once or twice and prefer a compact size over massive capacity
❌ Who Should Skip All of These?
If you need a power bank strictly for airline travel and want something under 100Wh that fits in a jacket pocket, the HELLEE is your only option here. The LanLuk and RGVOTA are both too large to fly with, so if you’re a frequent flyer who needs maximum power, you’ll want to look for a slim 20000mAh unit that’s still flight-safe.
For most people who just want a reliable battery for everyday use, I’d grab the HELLEE for its portability. But if you’re packing for a week-long camping trip or need to keep a whole family charged, the LanLuk with its massive 40800mAh capacity and built-in cables is the clear winner in my book.
Frequently Asked Questions
Which power bank has the biggest capacity: LanLuk, RGVOTA, or HELLEE?
The LanLuk wins this one hands down with a 40800mAh capacity, beating the RGVOTA’s 38800mAh by a small margin and absolutely crushing the HELLEE’s 15000mAh. If you want the longest runtime between charges, the LanLuk is your pick. Just remember that both the LanLuk and RGVOTA are too big to take on a plane, while the HELLEE is flight-safe.
Is the HELLEE worth it over the LanLuk for travel?
For air travel, absolutely. The HELLEE is the only one here that’s flight-safe, and at just 7.09 ounces it’s super portable. The LanLuk is 14.5 ounces and explicitly says it cannot be carried on flights. If you fly often, the HELLEE is the obvious choice, even with its smaller 15000mAh capacity.
Which power bank charges devices the fastest?
The LanLuk takes the lead here with 25W PD fast charging that it claims is up to 4x faster than standard power banks. The HELLEE is close behind at 22.5W fast charging, and the RGVOTA supports PD USB-C in and out but doesn’t specify a wattage. For the fastest top-ups, I’d go with the LanLuk.
Can I charge multiple devices at once with these power banks?
Yes, all three can handle multiple devices. The LanLuk supports up to 5 devices at once with 3 output ports and 2 built-in cables. The RGVOTA has 5 output ports for charging a group, and the HELLEE actually tops them all with 6 output ports. The HELLEE is the best pick if you need to charge the most devices simultaneously.
Which power bank is the most portable and lightweight?
The HELLEE is the clear winner here. It weighs just 7.09 ounces and measures 4.56 x 2.67 x 0.86 inches, roughly the size of a small smartphone. The LanLuk is much heavier at 14.5 ounces, and the RGVOTA is similar at 15 ounces. If you want something you can actually carry in your pocket, get the HELLEE.
Does the RGVOTA have built-in cables like the LanLuk?
No, it doesn’t. The LanLuk is the only one of the three with built-in cables — it includes USB-C and iOS output cables right in the unit. The RGVOTA and HELLEE both require you to bring your own cables, though the HELLEE does have a built-in cable as well. If you hate carrying extra cords, the LanLuk or HELLEE are your best bets.
My Final Verdict
The LanLuk Portable Charger is my clear overall winner because it packs the highest capacity at 40800mAh, comes with three built-in cables, and delivers 25W PD fast charging — all for a price that’s hard to beat. If you need maximum power for long trips or emergencies, this is the one. The HELLEE is the runner-up for travelers who need something flight-safe and lightweight at just 7.09 ounces.
If you’re still on the fence, ask yourself this: are you flying or staying on the ground? For air travel, grab the HELLEE. For road trips, camping, or power outages, the LanLuk’s massive 40800mAh capacity and built-in cables make it the no-brainer choice.
