My Anker Astro E5 15000mAh has given up the ghost. I came back from vacation to find the last LED light permanently on and refusing to turn off. Charging the device became a problem as it never went past the last LED light. So much for buying directly from the manufacturer. Maybe the battery discharged too much and something died within.
Anyway I decided to pick up another power bank and instead of buying from Amazon yet again, I decided to just buy one from SebufTech Ventures.
Mum and lil sis have been using their Romoss Sense 4 Power bank for months now without any issues so I decided I would have to get that one.
The Romoss Sense 4 comes with a capacity of 10400mAh of which I think close to 70% can be used for charging devices. I’ll talk about how I got to that conclusion soon. It has one input and 2 output outlets as well as 4 led lights and a power button.
See images below.

Operating this power bank is as easy as connecting your phone or tablet to the power bank using the supplied USB cable and then pushing the power button once to start the charging process.
Once charging is done, the device automatically shuts down on its own.
You know there’s need to recharge the device once the last LED light starts blinking. It’s highly recommended to stop using the power bank as soon as the last LED light starts blinking to avoid damaging the battery
Pros of The Romoss Sense 4 Power Bank
- It allows you to charge two devices at a time. One of the outlets supports up to 2.1A charging while the other supports 1A charging.
- You can recharge the Romoss Sense 4 using the USB port of your computer though that will be pretty slow.
- The Romoss Sense 4 can be recharged while it’s being used in charging other devices
Cons of The Romoss Sense 4 Power Bank
- Its input port only supports up to 1A so it takes 13 hours to recharge the Romoss Sense 4 completely.
- It doesn’t come with a carry case and neither does it come with a charging adapter which seems to be the norm with power banks these days. I ended up getting a 2.4A Belkin spare wall charger as I like having a charger for each gadget for situations whereby I have to charge all my gadgets at the same time.
- It only comes with a generic usb cable so you can’t charge other devices that don’t use the regular micro USB connector cable.
- No English Manual available in the pack.
With regards to actually battery capacity that’d available to the end user, I was able to get 70% which translated into charging my 4000mAh Lenovo P780 from zero once and my BlackBerry Z10 from zero once and up to 82% a second time.
I have to admit that the Romoss Sense 4 was quite slow in charging my Lenovo P780. It did so at a rate of 11% per hour but that probably has to do with the chemistry of the Lenovo P780 battery I guess. Charging my BlackBerry Z10 was fast though.
The Belkin 2.4amp works pretty well as it charges my Lenovo P780 in a little over 2 hours unlike the usual 4 hrs. Charging my Lenovo Yoga 8 tablet takes 3hrs 30 minutes instead of 5hrs 30 minutes using this charger.

I was looking for the English language manual and that was what brought me to your site.I got my Romoss sense 4 104000Mah yesterday. And coincidentally, I bought it from the exact same store on Konga you bought yours.
Nice review I must say.And thanks for the english language manual.
@Dre Lol. You’re welcome. I hope you enjoy your purchase 😆
I bought a romoss sense 4. I have been using this for about two weeks without a problem until today. It won’t charge my phone anymore. It shows that it’s charging but my phone battery will just keep draining. I’ve tried different cables. I charged my phone the usual way (plugged in to the socket) and it worked. What could possibly be wrong? :(
@Cher the powerbank is probably busted. Mine still works though it doesn’t charge as fast as its meant to. I’m planning on switching to Xiaomi’s powerbank soonest
UPDATE: I discovered there’s a fluke in the design of the ports. The port with 2 bolt signs is actually the 1A port while that with 1 bolt sign is the 2A port. So mine still works pretty good :D
Dear sir,
I have a Romoss 10400 bank battery it was working well but now for two days I’m trying to charge my mobile but it won’t work. I connect it as usual and press on the bank battery like always but it gives the orange light for some seconds and go off without charging. The bank battery is full.
Appreciating your feedback.
regards,
Wissam
@Wissam I haven’t experienced such on mine. Have you tried leaving it plugged into the wall adapter for a few hours then trying it out again to see if it charges?
Have you tried using another cable for charging?
mine says input is 2.1A max whereas yours is 1A only, though i’ve just bought mine last month.
@7600 there seems to be several models in the market. Maybe they’ve revised it and increased the input capacity. 2.1A should charge faster than 1A. I hope that’s your case
I have d romoss power bank of 10400mah and it only charge my bbz3 of 2500mah barely twice……can it be because am using a BlackBerry USB instead of d one that came with it?
@Dare do please note that charging capacity also depends on if you’re actively using the phone while charging it. The tests I ran were while charging the phone mostly in airplane mode
Chukwudi, I once had a power bank that packed 12000mAh. It could charge 2 devices at the same time too. It died in a short time. Personally, and I stand to be corrected, when a power bank’s rating comes in 5digits, it gets to be not so efficient.
I may be wrong on this too but the Romoss Sense 4 looks to be physically heavy. Not saying I haven’t seen power banks lighter than the Etisalat one. Just saying a power bank shouldn’t seem like one is lugging an extra cell phone.
@Nonye: lol. Some power banks are just serious on chance things. I always avoid high capacity power banks from unknown brands as they are mostly fake and the qualify of the batteries used within they power bank mighty be fishy.
Funny you should say the ROMOSS Sense 4 looks heavy as it’s actually lighter than my previous Anker Astro E5. Then again the higher the battery capacity the higher the weight of the power bank…. If I’m not wrong.
Wonder why I haven’t seen anyone with the Etisalat-branded power bank. Costs 5000naira. 5200mAh, and can only charge a device at a time. But it works very fine. Charges very fast too.
@Nonye: N5000 for 5200mah is quite expensive if you ask me oh
