LiitoKala have emerged as a major producer of battery chargers. Their products are humble in appearance and humble in price, but there's nothing humble about their electronics or charging algorithms which ensure you get the best return on your investment in lithium ion batteries. They also offer amazing versatility, charging all standard sizes of Li-Ion and NiMh (e.g. rechargeable AA and AAA) batteries and working as powerbanks so you can draw energy from a Li-Ion to charge your cellphone or other device when you're in the bundu!
