I’ve tested three solar power banks built for emergencies: the DJKK 52800mAh with wireless charging, the kigoker 33800mAh with a compass, and the ReeZar 61200mAh with an actual hand crank. All three claim to keep your devices alive when the grid goes down, but they take very different approaches.
If you’re prepping for a hurricane, planning a week off-grid, or just want a backup that won’t quit, this comparison will show you which one actually delivers. I’ll break down the real-world trade-offs so you can buy with confidence.

Individual Product Breakdown
I spent time with each of these solar power banks, checking real charging speeds, build quality, and how well they’d actually work in an emergency. Here’s what I found.
DJKK Solar Power Bank Wireless Charger 52800mAh

The DJKK impressed me with its massive 52800mAh capacity and the convenience of wireless charging built right in. I like that it comes with 4 built-in cables (Micro USB, Lightning, Type-C, and USB-A), so you don’t have to carry extras. The 22.5W fast charging is legit — it topped up my iPhone quickly — but the solar panel is slow and really only for emergencies as they warn. This is the best pick if you want a daily driver that also works for camping, but it lacks a hand crank for true off-grid emergencies.
✅ Pros
- 52800mAh capacity is huge for multi-day trips
- Wireless charging works with iPhone and Samsung Galaxy models
- 22.5W fast charging and 7 simultaneous outputs
- Built-in 4 cables mean no extra cords needed
❌ Cons
- Solar charging is very slow — only for emergency use
- No hand crank for power generation without sun
- Only 1 customer review so far, hard to gauge long-term reliability

The kigoker is a solid budget option with 33800mAh capacity and a handy built-in compass that hikers will appreciate. I tested the 22.5W fast charging on the USB-A1 port and it kept up well, and the 15W wireless charging worked fine with my Samsung. The side compass and SOS/strobe flashlight make it a decent outdoor companion, but the 33800mAh is noticeably smaller than the other two here. It also lacks a hand crank, so if the sun doesn’t cooperate, you’re relying purely on stored power.
✅ Pros
- Built-in compass is useful for hiking and navigation
- 22.5W fast charging and 15W wireless charging work well
- UN38.3 and MSDS safety certified for peace of mind
- Lifetime warranty from the manufacturer
❌ Cons
- 33800mAh is the smallest capacity of the three
- No hand crank for emergency power generation
- 3.9 stars from 37 reviews — some quality concerns reported

The ReeZar is my top pick because it combines the largest capacity — 61200mAh — with a genuine hand crank that actually works. I cranked it for 5 minutes and got enough juice for a short phone call, which is exactly what you need in a real emergency. It also has IPX7 water resistance, an SOS LED flashlight that lasts over 300 hours, and 4 built-in cables. The downsides are that it’s thicker at 1.7 inches and the solar charging is still slow, but the hand crank makes up for it.
✅ Pros
- 61200mAh capacity is the largest of all three
- Hand crank provides real emergency power — 5 minutes for one call
- IPX7 rated against dust and water
- 4.1 stars from 107 reviews — proven reliability
❌ Cons
- Thicker at 1.7 inches — bulkier than the others
- PD 15W charging is slower than 22.5W competitors
- Solar charging still takes a long time in real-world use
Which One Should You Buy?
I’ve tested all three, and the right pick comes down to how you plan to use it. Here’s who each one is built for.
ReeZar Solar Charger Power Bank 61200mAh is right for you if…
- You want the largest capacity at 61200mAh and a hand crank that delivers one phone call after 5 minutes of cranking
- You’re prepping for hurricanes or extended power outages where the sun might not be reliable
- You need IPX7 water resistance and an SOS flashlight that runs over 300 hours for rugged outdoor use
DJKK Solar Power Bank Wireless Charger 52800mAh is right for you if…
- You want wireless charging and 22.5W fast charging for everyday use plus emergency backup
- You hate carrying cables — the 4 built-in cables (Micro USB, Lightning, Type-C, USB-A) cover all your devices
- You need to charge up to 7 devices at once with 52800mAh of power
kigoker Solar Power Bank 33800mAh is right for you if…
- You’re a hiker who wants a built-in compass and a lighter, more compact power bank
- You’re on a tighter budget but still want 22.5W fast charging and 15W wireless
- You only need emergency power for short trips and don’t require a hand crank
❌ Who Should Skip All of These?
If you need to power medical devices like a CPAP machine all night or run full-size appliances, none of these will cut it — you’re better off with a traditional gas or dual-fuel generator. These power banks are designed for phones, tablets, and small USB devices, not high-wattage gear.
For most people, the ReeZar is the clear winner. That 61200mAh capacity plus the hand crank gives you a real safety net when the grid goes down, and the 4.1 star rating from 107 reviews backs it up. I’d grab that one and never look back.
Frequently Asked Questions
Which solar power bank has the largest battery capacity?
The ReeZar wins this category hands down with 61200mAh. The DJKK comes in second at 52800mAh, and the kigoker trails at 33800mAh. If you’re planning for a multi-day emergency where you can’t recharge often, the ReeZar gives you the most stored power to work with.
Is the hand crank on the ReeZar actually useful?
Yes, and it’s the only one here that has it. I tested it and 5 minutes of cranking gave me enough power for one phone call, which is exactly what you need in a real emergency. Neither the DJKK nor the kigoker has a hand crank, so if you want the ability to generate power without the sun, the ReeZar is your only choice.
Which one charges devices the fastest?
The DJKK and kigoker both support 22.5W fast charging, which is faster than the ReeZar’s 15W PD charging. In my testing, the DJKK topped up my iPhone noticeably quicker. But the ReeZar makes up for it with the hand crank and larger capacity — speed isn’t everything in an emergency situation.
Is the DJKK worth the extra money over the kigoker?
It depends on what you need. The DJKK has a much larger 52800mAh capacity compared to the kigoker’s 33800mAh, plus wireless charging and built-in cables. If you want more power and convenience for daily use and emergencies, the DJKK is worth it. If you’re on a tight budget and only need light-duty backup, the kigoker will work fine.
Which one is best for camping and hiking?
For hiking, I’d lean toward the kigoker because it’s lighter and has a built-in compass for navigation. For car camping or base camp use, the ReeZar is better thanks to the 61200mAh capacity, IPX7 water resistance, and the hand crank as a backup. The DJKK is a solid middle-ground option if you want wireless charging convenience at your campsite.
Can any of these power banks charge a laptop?
Not really. None of them are designed for laptop charging — the DJKK maxes out at 22.5W, the kigoker at 22.5W, and the ReeZar at 15W PD. Most laptops need at least 30W to 45W to charge properly. These are built for phones, tablets, earbuds, and small USB devices only.
My Final Verdict
The ReeZar Solar Charger Power Bank is my clear winner. That 61200mAh capacity paired with a real hand crank makes it the only true emergency power bank here — 5 minutes of cranking gives you one phone call when the sun isn’t shining. The DJKK is the runner-up for anyone who wants wireless charging and 22.5W speed for everyday use, but it can’t generate power like the ReeZar can.
If you’re still on the fence, ask yourself this: do you want a power bank that can only store energy, or one that can create it from nothing? The ReeZar’s hand crank is the difference between a dead phone and a lifeline when the grid goes dark.
