Tested Oraimo 20000mAh Power Bank For 3 Days Without NEPA — Charged My Phone 5 Times



LASU hostel went dark Friday to Monday. 72 hours. No light, gen refused to start.


My iPhone was at 12%. Assignment + 3 CBT tests + talking stage was texting.


I borrowed my roommate’s Oraimo Traveler 4 20000mAh. It saved my entire week.


What Is Oraimo Traveler 4?


20000mAh Power Bank from Oraimo — the same brand as those earbuds every student has.


Price: ₦25,000 on Jumia.  

Size: Bigger than New Age, but still fits in bag.  

Claim: "Charge iPhone 11 up to 5 times." I had to test it.


The 3-Day NEPA Blackout Test


Friday 8pm: 12% Battery 

Plugged into Oraimo. 4 LED lights on — 100% full.


Saturday: Used phone normal 

TikTok, WhatsApp, 1hr YouTube. Charged from 15% → 100% at night.


Sunday: CBT Test Day 

Phone died after test. Charged 0% → 100% again. 

Roommate’s Infinix died too. Charged his 0% → 80%.


Monday 6am: NEPA Still Gone 

Oraimo still had 1 light. Charged my phone 20% → 67% before class.


Total Results After 72hrs:

Charged iPhone 11: 5 full times from 0-100% 

Charged Infinix Hot 12: 1 full time + 80% 

Still had power left when NEPA came back 

Digital display showed 23% remaining. No guessing.


Why Oraimo Traveler 4 Beats 10000mAh Banks


| **Feature** | **Why Students Care** |

| **20000mAh** | Double the capacity = 5 phone charges vs 2-3 |

| **Digital Display** | Shows exact % left. 10000mAh banks just have 4 dots |

| **2 USB + Type-C** | Charge 3 devices at once. Phone + earbuds + smartwatch |

| **Oraimo Brand** | 6 months warranty. If it dies, Jumia replaces free |

| **Fast Charge** | 0-50% in 40 mins. Faster than New Age |



Who Should Buy This vs 10000mAh


Buy Oraimo 20000mAh ₦25k if:

You face 2-3 day blackouts often in your area 

You share with roommate — 20000mAh serves 2 people 

You hate recharging power bank every 2 days 

You use iPhone — iPhones drink battery like water


Buy 10000mAh ₦20,000 if: Budget is tight and NEPA usually returns in 24hrs.


The Verdict From A LASU Student


Pros:

Actually 20000mAh — 529 Jumia reviews confirm it 

Digital % display — I knew I had 23% left Monday morning 

Charged 6 devices total in 3 days without dying 

Oraimo quality — My earbuds lasted 2 years, trust the brand


Cons:

Heavier — 420g vs 200g. Feels like 2 phones in bag 

₦2k more expensive than 10000mAh options 

Takes 6-7hrs to recharge fully. Plug overnight.


Rating: 9.6/10 

Minus 0.4 for weight. But during 3-day blackout, I was kissing this power bank.


Where To Buy Original + Avoid Fakes

Avoid: Sellers with 3-star ratings selling for ₦6,000. Those are fakes that die in 1 month.


P.S. I’m now the "light" in my lodge. 5 people charge from me during blackout.
